Roundup of Global Volcanic Activity – New Activity for the Week 23 December 2020 – 29 December 2020
Kilauea – Hawaiian Islands (USA) : HVO reported that the eruption from N and W fissure vents on the inner walls of Kilauea’s Halema`uma`u Crater continued to feed a growing lava lake during 23-29 December. Lava erupted from the N and W vents during 23-26 December with lava fountains that were sometimes 10 m high. The lake level rose above the N vent by 0300 on 26 December; later that day, volcanologists noted that the lake was slowly draining at that location. The W vent continued to feed the lake during 27-29 December. An island of cooler, solidified lava (250 m by 135 m in dimension on 28 December) slowly floated around on the lava lake’s surface. The island’s surface was about 6 m above the surface of the lava lake and was covered in tephra, possibly remnants of explosive activity generated when lava first reached the water lake. The depth of the lava lake increased from 155 m to 169 m during 23-24 December. It continued to rise and was 176 m deep by 1400 on 25 December, though a new, narrow, black rim along the N edge suggested that the lake had briefly been 1-2 m deeper, and then drained back. The lake remained 176-177 m deep through 28 December, but by 29 December had deepened to 180 m. The lake volume was an estimated 22 million cubic meters, and was 770 by 490 m in dimension by 29 December. Sulfur dioxide emissions decreased over the week, from around 30,000-40,000 tonnes/day on 23 December, to 20,000 tonnes/day on 25 December, 5,000-5,500 tonnes/day during 26-27, and finally dropping to 3,000 tonnes/day during 28-29 December. The emission plume carried Pele’s Hair and Pele’s Tears SW, depositing the tephra in areas downwind, including on HVO monitoring equipment and solar panels.
Kirishimayama – Kyushu (Japan) : JMA reported that the number of volcanic earthquakes at Shinmoedake (Shinmoe peak, a stratovolcano of the Kirishimayama volcano group) began to increase on 18 December and remained elevated. A total of 300 earthquakes were located beneath the summit crater during 16-25 December. No changes were detected in deformation and emission data. The Alert Level was raised to 2 (on a scale of 1-5) on 25 December, and the public was warned to exercise caution within a 2-km radius of the crater.
Ruapehu – North Island (New Zealand) : On 28 December GeoNet reported that during the previous week the temperature of Ruapehu’s crater lake water slightly decreased from 43 to 41 degrees Celsius. Moderate-to-strong levels of volcanic tremor were recorded along with a small number of shallow volcanic earthquakes. The largest volcanic earthquake was an M 2.2 (on 26 December) which was uncommonly large, and combined with elevated tremor indicated ongoing unrest. The Volcanic Alert Level remained at 2 and the Aviation colour Code remained at Yellow.
Soufriere St. Vincent – St. Vincent : A new effusive eruption had built a lava dome in the summit crater of Soufrière St. Vincent when observed on 29 December by personnel from the National Emergency Management Organisation (NEMO), St. Vincent and the Grenadines, and the Alert Level was raised to Orange (the second highest level on a four-colour scale). The observers noted that the small black-coloured dome had grown on the WSW edge of the 1979 lava dome. The University of the West Indies Seismic Research Centre (UWI-SRC) stated in a press briefing that seismicity at the volcano began to increase in early November and changes in the water lake and fumarolic area were noted on 16 December. A persistent thermal anomaly had been identified in satellite data over the previous couple of days, which is what prompted the NEMO field visit.
Suwanosejima – Ryukyu Islands (Japan) : JMA reported that eruptive activity at Suwanosejima’s Ontake Crater increased on 21 December with more frequent explosions; a total of 423 explosions were recorded during 21-28 December. At 0248 on 28 December a large eruptive event ejected large bombs 1.3 km SE of the crater and produced a plume that rose 200 m above the crater rim and entered weather clouds. The Alert Level was raised to 3 (on a 5-level scale).
Tengger Caldera – Eastern Java (Indonesia) : PVMBG reported that during 26-27 December white-and-gray plumes rose 50-700 m above the summit of Tengger Caldera’s Bromo cone. At 0550 on 28 December a gas-and-ash emission rose at least 500 m above the summit according to an observer. Ashfall was reported in the Ngadirejo area, about 5 km NE. The Alert Level remained at 2 (on a scale of 1-4), and visitors were warned to stay outside of a 1-km radius of the crater.

Britain and France – Hurricane-force winds reaching up to 170 kph and heavy rainstorms have battered parts of Britain and France, disrupting train services and stranding drivers in floodwaters. The Isle of Wight saw Storm Bella’s strongest gusts hit 170 kph, while parts of the south coast of England and north Wales also saw gusts of around 129 kph. Flooding on the tracks caused train cancellations and delays in southern England, and a main train line into London was blocked by a fallen tree. In Wales, Western Power said the storm caused power cuts for 21,000 homes. Most of the services were restored Sunday but 1,700 homes still had no power supply. Across the Channel, nearly all of France was under storm warning on Sunday, with winds up to 145 kph registered at the top of the Eiffel Tower in Paris and heavy rains and gusts lashing the Atlantic coast, according to the national weather service and utility services. Thousands of homes in north-western France were deprived of electricity on Sunday due to storm Bella sweeping through the area, with wind guts of up to 120 km/h on the coast.

UK – More than 1,300 households have been urged by police to evacuate their homes due to a risk of flooding in parts of Bedfordshire as large swaths of the UK brace themselves for Storm Bella. Torrential rain has brought widespread flooding to the country, with people having to be rescued from vehicles and others evacuated from their homes. The arrival of Storm Bella on Boxing Day will bring further downpours and winds of up to 70mph in exposed coastal locations, according to the Met Office.
Recalculated Heat
The world may have less time than expected to curb carbon emissions and avert a life-threatening climate catastrophe after it was discovered that manmade greenhouse gases may have already warmed the planet by 18% more than predicted.
“Climate change hasn’t suddenly got worse. It’s just our estimate of how much warming has taken place has improved,” says Tim Osborn of Britain’s University of East Anglia.
The findings come as 2020 appears to be vying with 2019 as the second-warmest year on record.
The British Met Office predicts 2021 is still likely to at least be among the six warmest years on record, chilled a bit by the ongoing moderate La Niña ocean-cooling in the Pacific.

Bird Blackout
A New Zealand South Island village has switched off all of its streetlights in an attempt to stop young birds from crash-landing on roadways.
Wildlife experts say the Westland petrel fledglings are possibly mistaking the streetlights of Punakaiki for the bioluminescent fish they typically eat. The town hosts about 6,000 breeding pairs of the rare birds each March, which is celebrated with a festival.
But the introduction of blue-white LED lights last year has some local bird watchers believing that it’s confusing the seabirds even more than usual, causing them to crash onto roads and sometimes be struck by cars.
Trump’s Border Wall Affects Wildlife
The accelerated construction of the U.S.-Mexico border wall over the past year has disrupted animal movements, caused mountains to be dynamited and toppled century-old saguaro cactus.
“Interconnected landscapes that stretch across two countries are being converted into industrial wastelands,” Randy Serraglio of the Center for Biological Diversity in Tucson told The Associated Press.
Field cameras at southeastern Arizona’s San Bernardino National Wildlife Refuge have recently captured 90% fewer movements of animals like mountain lions, bobcats and javelinas.
“This wall is the largest impediment to wildlife movement we’ve ever seen in this part of the world,” said Myles Traphagen of the Wildlands Network.
Global Temperature Extremes
The week’s hottest temperature was 110 degrees Fahrenheit (43.3 degrees Celsius) in Nullagine, Western Australia.
The week’s coldest temperature was minus 63.0 degrees Fahrenheit (minus 52.8 degrees Celsius) in Verkhoyansk, Siberia.
Temperatures were tabulated from the more than 10,000 worldwide synoptic weather stations. The United Nations World Meteorological Organization sets the standards for weather observations, and provides a global telecommunications circuit for data distribution.

Roundup of Global Volcanic Activity – Ongoing Activity for the Week 16 December 2020 – 22 December 2020
Aira – Kyushu (Japan) : JMA reported nightly incandescence from Minamidake Crater (at Aira Caldera’s Sakurajima volcano) during 14-21 December and that the sulfur dioxide emission rate remained high. Four explosions were recorded during 16-18 December. One of the explosions, at 1959 on 17 December, generated a plume that rose 3 km above the crater rim and ejected bombs 1.3-1.7 km away from the crater. Another explosion, at 0439 on 18 December, produced a plume that rose 1.8 km and ejected bombs 1-1.3 km away from the crater. The Alert Level remained at 3 (on a 5-level scale).
Dukono – Halmahera (Indonesia) : Based on satellite and wind model data, the Darwin VAAC reported that during 18-19 December ash plumes from Dukono rose to 2.1 km (7,000 ft) a.s.l. and drifted SE and E. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km exclusion zone.
Ebeko – Paramushir Island (Russia) : Volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, observed explosions during 11-12 and 15-17 December that sent ash plumes up to 3 km (10,000 ft) a.s.l. and drifted NE, SE, and S. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).
Etna – Sicily (Italy) : INGV reported that strong activity at Etna’s Southeast Crater (SEC) included fountaining and lava flows on 21 December. Tremor amplitude had gradually increased on 20 December but weather conditions prevented visual observations. During the morning of the 21st Strombolian activity occurred at three vents. By 0800 tremor amplitude suddenly increased, and by 1000 lava fountaining from at least two vents was observed in thermal camera images, along with an eruption plume to 3 km (10,000 ft) a.s.l. A lava flow emerged from the SW part of the cone, which had collapsed on 13 December, and traveled SW before branching W and E. A second flow from the NE side of the cone traveled E into the Valle del Bove. Lava fountaining ended around noon, with a simultaneous decrease in tremor amplitude. During the morning of 22 December a few small phreatic explosions were visible in webcam images, likely generated from the interaction of snow and lava. The front of the active SW flow reached 2,500 m elevation. By 1741 both flows were cooling down and no longer advancing.
Ibu – Halmahera (Indonesia) : PVMBG reported that at 1826 on 19 December an ash plume from Ibu rose 400 m above the summit and drifted N. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to stay at least 2 km away from the active crater, and 3.5 km away on the N side.
Karymsky – Eastern Kamchatka (Russia) : KVERT reported that a thermal anomaly over Karymsky was visible during 11-12 and 17 December. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).
Klyuchevskoy – Central Kamchatka (Russia) : KVERT reported that Strombolian and sometimes Vulcanian activity at Klyuchevskoy continued during 11-18 December and lava advanced down the Kozyrevsky drainage on the S flank. A large bright thermal anomaly was identified daily in satellite images. A steam-and-gas plume with some ash rose to 6 km (19,700 ft) a.s.l. and drifted 120 km NE on 13 December. The Aviation colour Code remined at Orange (the second highest level on a four-colour scale).
Nishinoshima – Japan : JMA reduced the exclusion zone for Nishinoshima from a radius of 2.5 to 1.5 km around the summit crater on 18 December; eruptive activity ended in August. Fumarolic and high-temperature areas remained visible.
Popocatepetl – Mexico : CENAPRED reported that each day during 16-22 December there were 112-231 steam-and-gas emissions from Popocatépetl, some of which contained minor amounts of ash. A gas, steam, and ash plume drifted SE on 22 December. The Alert Level remained at Yellow, Phase Two (middle level on a three-colour scale).
Reventador – Ecuador : IG reported that a high level of activity continued to be recorded at Reventador during 16-22 December; adverse weather conditions sometimes prevented visual conformation. Seismicity was characterized by 40-109 daily explosions, volcano-tectonic and harmonic tremor events, and long-period earthquakes as well as signals indicating emissions. Gas, steam, and ash plumes, observed sometimes multiple times a day with the webcam or reported by the Washington VAAC, rose as high as 1 km above the summit crater and drifted mainly NW and W. Crater incandescence and incandescent blocks rolling 600 m down the NE and S flanks were observed nightly. The 450-m-long lava flow on the NE flank remained active but did not advance.
Sangay – Ecuador : IG reported a high level of activity at Sangay during 16-22 December. Seismicity was characterized by 20-127 daily explosions, occasional harmonic tremor, long-period earthquakes, and signals indicating emissions. Weather clouds often prevented visual observations of the volcano, but the Washington VAAC and IG webcams recorded daily ash plumes that rose as high as 2.4 km above the summit and drifted mainly NW, W, and SW. Seismic signals signifying lahars were recorded during 16-18 December.
Sheveluch – Central Kamchatka (Russia) : KVERT reported that a thermal anomaly over Sheveluch was identified in satellite images during 11-18 December. On 22 December residents of Ust-Kamchatsk Village, 85 km SE, observed ash plumes rising to 8 km (26,200 ft) a.s.l. and drifting 42 km NE. The Aviation colour Code was raised to Red (the highest level on a four-colour scale). Just over an hour later ash plumes rose 6.5-7.5 km (21,300-24,600 ft) a.s.l. and drifted 130 km E; the Aviation colour Code was lowered to Orange.
Suwanosejima – Ryukyu Islands (Japan) : JMA reported nighttime incandescence and intermittent eruptive activity at Suwanosejima’s Ontake Crater during 11-18 December. A total of five explosions were recorded, ejecting bombs up to 500 m away from the crater and producing gray-and-white plumes that rose 1.6 km above the crater rim. Ashfall was reported in Toshima village (4 km SSW). The Alert Level remained at 2 (on a 5-level scale).
Villarrica – Chile : POVI reported that four ash emissions at Villarrica were visible in webcam images on 16 December. SERNAGEOMIN stated that two ash pulses were associated with long-period (LP) events at 1146 and 1156 that same day; the first ash emission rose 160 m above the crater rim and drifted NW while the second rose 280 m and drifted 500 m NE. At 1716 on 17 December an ash emission associated with an LP event rose 720 m and drifted ESE. The Alert Level remained at Yellow, the second lowest level on a four-colour scale. ONEMI maintained an Alert Level Yellow (the middle level on a three-colour scale) for the municipalities of Villarrica, Pucón (16 km N), Curarrehue, and the commune of Panguipulli, and the exclusion zone for the public of 500 m around the crater.

Roundup of Global Volcanic Activity – New Activity for the Week 16 December 2020 – 22 December 2020
Cerro Hudson – Chile : SERNAGEOMIN reported that a notable change in seismicity at Cerro Hudson was characterized by an increase in the frequency and magnitude of volcano-tectonic (VT), hybrid (HB), and long-period (LP) signals during 1-15 December. Two swarms of VT earthquakes were recorded during 10-11 December, with the largest event, a local M 2.9, located 4.7 km ESE of the caldera’s center at a depth of 4.6 km. The largest of five HB signals was a local M 3.1, located 4 km ESE at a depth of 4.3 km. The earthquake locations suggested a relatively shallow source SE of the caldera. No deformation or surficial changes were observed. The Alert Level was raised to Yellow (second highest level on a four-colour scale) on 22 December, based on the increased seismicity. ONEMI warned the communities of Aysén and RÃo Ibáñez, declaring a status of “Preventive Early Warning”, a level in between Green and Yellow.
Kilauea – Hawaiian Islands (USA) : HVO reported that a new eruption at Kilauea began on 20 December, after almost a month of pre-eruptive activity that included a dike intrusion. An earthquake swarm on 30 November centered in the middle of the caldera was recorded followed by periods of increased seismicity in the upper East Rift Zone. Spikes in seismicity began on 2 December; at 1745 earthquakes intensified beneath the S part of the caldera; tiltmeters simultaneously recorded accelerated deformation, resulting in about 8 cm of caldera floor uplift. The data suggested that a small intrusion had a volume equivalent to the amount of lava erupted in just 1-2 hours from Fissure 8 during the 2018 eruption. On 3 December seismcity and deformation decreased to pre-intrusion levels.
Lewotolo – Lomblen Island (Indonesia) : PVMBG reported that the eruption at Lewotolo continued during 16-22 December. Gray-and-white ash plumes were visible daily, rising as high as 800 m above the summit. Strombolian explosions were visible most nights ejecting material 100-200 m above the summit crater. Rumbling was heard most days. The Alert Level was remained at 3 (on a scale of 1-4) and the public was warned to stay 4 km away from the summer crater.
Merapi – Central Java (Indonesia) : BPPTKG reported that during 12-17 December white emissions from Merapi rose as high as 150 m above the summit. Rock avalanches traveled as far as 1.5 km down the Senowo drainage on the NW flank on 14 December. A comparison of photos taken on 11 and 15 December showed minor morphological changes in the summit area; drone video from 14 December revealed no new lava dome material in the summit crater. Seismic activity was less intense than the previous week. Electronic Distance Measurement (EDM) data continued to measure a distance shortening between points in the NW at a rate of 9 cm per day. The Alert Level remained at 3 (on a scale of 1-4).
Ruapehu – North Island (New Zealand) : GeoNet reported a warming trend of the crater lake water at Ruapehu, with a high temperature of 43 degrees Celsius. During an overflight to measure gas emissions the previous week, scientists observed that the lake was a uniform gray colour (suggesting it is well mixed) and some water overflow at the lake’s outlet. Gas output had increased in response to the heating cycle; the amounts of carbon dioxide (CO2) and sulfur gases (SO2 and H2S) in the plume were the largest measured in the past two decades. Short-lived pulses of volcanic tremor were coincident with gas emissions. The Volcanic Alert Level was raised to 2 and the Aviation colour Code was raised to Yellow on 21 December.

Arctic Report Card 2020
The average annual land-surface air temperature in the Arctic measured between October 2019 and September 2020 was the second-warmest since record-keeping began in 1900, and was responsible for driving a cascade of impacts across Arctic ecosystems during the year.
Extremely high temperatures across Siberia during spring 2020 resulted in the lowest June snow extent across the Eurasian Arctic observed in the past 54 years.
The 2020 Arctic minimum sea ice extent reached in September was the second-lowest in the satellite record. Overall thickness of the sea ice cover is also decreasing as Arctic ice has transformed from an older, thicker, and stronger ice mass to a younger, thinner more fragile ice mass in the past decade.
Extreme wildfires in the Sakha Republic of northern Russia during 2020 coincided with unparalleled warm air temperatures and record snow loss in the region.
Pacific Arctic bowhead whales have rebounded in the past 30 years, due to increases in both local plankton blooms and transport of increased krill and other food sources northward through the Bering Strait, a signal of long-term warming in the Arctic Ocean.

Philippines – At least two people were killed and hundreds forced to flee their inundated homes in the Philippines as torrential rain triggered flooding and landslides in the storm-battered archipelago on Saturday. Huge waves smashed into a coastal village on Lapu-Lapu island in the central province of Cebu on Friday night, wiping out dozens of houses and leaving around 290 people homeless.
Deadly Skin Disease Affects Dolphins
In collaboration with Australian researchers, The Marine Mammal Center has found that the increasing frequency and severity of storm systems drastically decrease the salinity of coastal waters, causing fatal skin disease in dolphins worldwide.
Scientists at The Marine Mammal Center in Sausalito, CA — the largest marine mammal hospital in the world — and international colleagues have identified a novel skin disease in dolphins that is linked to climate change. The study is a groundbreaking discovery, as it is the first time since the disease first appeared in 2005 that scientists have been able to link a cause to the condition that affects coastal dolphin communities worldwide. Due to the decreased water salinity brought upon by climate change, the dolphins develop patchy and raised skin lesions across their bodies — sometimes covering upwards of 70 percent of their skin.

La Niña Persists – U.S. forecasters predict there is a 95% chance the current moderate La Niña episode will prevail until at least March, triggering a unique set of global weather shifts. They add there is a chance it will peak in the strong range during January. While El Niños typically last just one year, La Niñas often fade, then redevelop the following year. Australian meteorologists say the ocean-cooling across the tropical Pacific can probably be linked to a cyclone-like storm that was lashing the coast of Queensland in mid-December. The deepening climate crisis is also said to be a factor in that storm and accompanying floods.
Fiji – Cyclone Yasa slammed into Fiji’s second-largest island Thursday, tearing roofs off buildings as it triggered flash floods and landslides in the Pacific island nation. Yasa, which is expected to move out to sea early Friday, landed in the sparsely populated Bau province. There were no immediate reports of damage or casualties but social media posts showed flooded villages and corrugated sheeting blown off homes.
Brazil – At least 10 people died Thursday in floods and landslides sparked by heavy rains in Presidente Getulio, a town in southern Brazil’s Santa Catarina state, bordering Argentina, state officials said. Civil defense rescue teams were also searching for 12 missing persons in affected neighborhoods.
Pine Trees Under Siege
Rome’s iconic umbrella pine trees are under siege from a tiny insect known as the pine tortoise scale. Originally from North America, the invasive Toumeyella parvicornis has an oval shell that makes it look like a tortoise. It first appeared in Naples to the south five years ago, ravaging that city’s stone pines.
Agronomists say it can kill trees within just two or three years by operating like a vampire, sucking sap then coating trees with a fungus that blocks photosynthesis. They are looking at natural predators to control the infestation since it is not practical to use pesticides in the bustling Italian capital. “In Europe, our pines have never seen this insect and have no defense mechanism,” said entomologist Antonio Garonna.
Pearl Penguin
The Galapagos National Park reports a white penguin that appears to have a rare genetic condition is living along the northern coast of Isabela Island. Park scientists say the leucism responsible for the white appearance of the Galapagos penguin differs from albinism because the bird has normal eye colour.
Global Temperature Extremes
The week’s hottest temperature was 111 degrees Fahrenheit (43.9 degrees Celsius) in Boulia, Queensland, Australia.
The week’s coldest temperature was minus 68.0 degrees Fahrenheit (minus 55.6 degrees Celsius) in Oimyakon, Siberia.

The countries with the 10 greatest number of Covid-19 cases:
Roundup of Global Volcanic Activity – Ongoing Activity for the Week 9 December 2020 – 15 December 2020
Aira – Kyushu (Japan) : JMA reported that during 7-14 December incandescence from Minamidake Crater (at Aira Caldera’s Sakurajima volcano) was often visible nightly and the sulfur dioxide emission rate remained high. Three explosions during 7-11 December produced ash plumes that rose as high as 2.4 km above the crater rim and ejected bombs 1.3-1.7 km away from the crater. An eruptive event at 0514 on 14 December produced a plume that rose 1.8 km and blended into weather clouds. The Alert Level remained at 3 (on a 5-level scale).
Dukono – Halmahera (Indonesia) : Based on satellite and wind model data, the Darwin VAAC reported that during 8-14 December ash plumes from Dukono rose 2.1-2.4 km (7,000-8,000 ft) a.s.l. and drifted in multiple directions. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km exclusion zone.
Ebeko – Paramushir Island (Russia) : Volcanologists in Severo-Kurilsk (Paramushir Island), about 7 km E of Ebeko, observed explosions during 8-9 December that sent ash plumes up to 3.5 km (11,500 ft) a.s.l. and drifted NE and SE. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).
Etna – Sicily (Italy) : INGV reported that during 7-12 December activity at Etna was similar to the previous week, characterized by intra-crater Strombolian activity at Northeast Crater (NEC), and Strombolian activity, lava effusion, and pyroclastic flows at the Southeast Crater (SEC). Additionally, infrequent ash emissions at the Bocca Nuova (BN) craters and some explosions and minor ash emissions at the Voragine (VOR) were also recorded. Webcam views of activity was limited due to weather conditions; a field visit was made on 14 December. Strombolian activity originated from the E and central vents at SEC ejected lava onto the inner crater walls. Occasional ash emissions dispersed quickly near the summit. Activity intensified at 2020 on 13 December and lava fountains formed around 2300. Collapses of the SW part of the SEC cone spurred a series of pyroclastic flows. At 2315 a small pyroclastic flow traveled down the SSW flank. A second pyroclastic flow began at 2316 and traveled 2 km down the SSW flank and covered Monte Frumento Supino cone (SSW). At 2330 a third and minor pyroclastic flow traveled SSW. Around the same time as the generation of the first two pyroclastic flows, two fissures opened on the SW flank of the SEC and produced lava flows to the S and SW until about 2350. A period of lava fountaining was visible during 0050-0110 and 0210-0223 on 14 December. During a field inspection on 14 December scientists confirmed the partial cone collapses and noted that the two lava flows (S and SW) were cooling. The S lava flow had widened at the near the base of SEC and formed four lobes. One of the lobes continued on and stopped just NW of cones that had formed in 2002-2003. The SW flow traveled SSW, branched, curved around the W part of Monte Frumento Supino, and then stopped. Explosive activity from central SEC vent continued, with roaring and sporadic ash emissions. An explosion at 1352 formed an ash plume that rose about 4 km and drifted S. Strombolian explosions deposited material outside of the crater.
Fuego – Guatemala : INSIVUMEH reported that 3-15 explosions were recorded per hour during 8-15 December at Fuego, generating ash plumes as high as 1.1 km above the crater rim that drifted 10-25 km generally S, SW, and W. Shock waves rattled buildings within 20 km of the summit. Block avalanches descended the Ceniza (SSW), Seca (W), Trinidad (S), Taniluyá (SW), El Jute, Las Lajas (SE), and Honda drainages; avalanches sometimes reached vegetated areas. Incandescent material was occasionally ejected 100-200 m. Ashfall was reported most days in several areas downwind including Morelia (9 km SW), Panimaché I and II (8 km SW), Finca Palo Verde, Santa SofÃa (12 km SW), El Porvenir (8 km ENE), San Pedro Yepocapa (8 km NW), and Sangre de Cristo (8 km WSW).
Kirishimayama – Kyushu (Japan) : JMA noted that no eruption had occurred at Shinmoedake (Shinmoe peak, a stratovolcano of the Kirishimayama volcano group) since 28 June 2018. Volcanic earthquakes with hypocenters just below Shinmoedake had increased around 17 November 2019, fluctuated afterwards, and then began a decreasing trend in mid-October 2020. Sulfur dioxide levels were generally low, deformation data showed no changes, and both fumarolic and geothermal area activity remained stable. The Alert Level was lowered to 1 (on a scale of 1-5) on 11 December.
Klyuchevskoy – Central Kamchatka (Russia) : KVERT reported that Strombolian and Vulcanian activity at Klyuchevskoy continued during 4-7 December and lava advanced down the Kozyrevsky drainage on the S flank. A large bright thermal anomaly was identified daily in satellite images. Steam-and-gas plumes with some ash rose to 7 km (23,000 ft) a.s.l. and drifted 130 km NW and NE. The Aviation colour Code remined at Orange (the second highest level on a four-colour scale).
Pacaya – Guatemala : INSIVUMEH reported that on 9 December a new lava flow emerged from a vent S of Cerro Chino, NNW of Pacaya’s summit, and traveled as far as 250 m WSW. The branched lava flow which had opened in October on the WSW flank was active, with lengths between 400 and 600 m. Avalanches of material from the new flow and the SW-flank lava flows descended 100 m. Strombolian explosions from the cone in Mackenney Crater were visible on most days during 9-15 December and ejected material as high as 150 m above the vent. Gray ash plumes were occasionally visible drifting S, SW, and W at generally low altitudes. On 12 December strong winds picked up ash deposits and created ash curtains that drifted 1.5 km away and dispersed. Lava flows on the SW flank varied in length between 500 m and 1,000 m. The NW-flank lava flow ceased effusing by 13 December.
Sabancaya – Peru : Instituto GeofÃsico del Perú (IGP) reported a daily average of 54 explosions at Sabancaya during 7-13 December. Gas-and-ash plumes rose as high as 2.8 km above the summit and drifted NW, W, and SW. Eight thermal anomalies over the crater were identified in satellite data. Minor inflation continued to be detected in areas N of Hualca Hualca (4 km N) and on the SE flank. INGEMMET stated that ashfall was noted in the towns of Cabanaconde (22 km NW), Pinchollo (20 km N), and Madrigal (20 km NE) during 9-10 December. The Alert Level remained at Orange (the second highest level on a four-colour scale) and the public were warned to stay outside of a 12-km radius.
Santa Maria – Guatemala : INSIVUMEH reported that during 9-15 December explosions at Santa MarÃa’s Santiaguito lava-dome complex generated ash plumes that rose as high as 900 m above the complex. The extrusion of blocky lava at the WSW part of Caliente dome generated block-and-ash flows that descended the NW, WSW, SW, and E flanks often reaching the base of the complex. The activity increased at 0430 on 11 December with notable avalanches of material and block-and-ash flows lava dome traveling down the W and SW flanks. Ash plumes drifted 15 km SW, causing ashfall in areas downwind including Finca Montebello, Loma Linda, and San Marcos Palajunoj. Activity remained elevated at least through 13 December; ash plumes drifted as far as 20 km W, SW, and S, and pyroclastic flows descended the flanks.
Semeru – Eastern Java (Indonesia) : PVMBG reported that the eruption at Semeru continued during 9-15 December. Incandescent material was ejected 50-100 m above the summit on 9 December and rock avalanches descended the Kobokan drainage 500 m on the SE flank. Explosions were recorded by the seismic network during 10-12 December but they could not be visually confirmed due to weather conditions. On 13 December a pyroclastic flow originating from the end of a lava flow traveled 1.5 km down the Kembar drainage (S flank), reaching a maximum distance of 3.5 km from the crater. The next day a pyroclastic flow traveled 3.5 km down the Kobokan drainage. Rock avalanches from the end of a lava flow traveled 300-1,500 m down both drainages during 14-15 December. The Alert Level remained at 2 (on a scale of 1-4), with a general exclusion zone of 1 km and extensions to 4 km in the SSE sector.
Sheveluch – Central Kamchatka (Russia) : KVERT reported that a thermal anomaly over Sheveluch was identified in satellite images during 4-11 December. The lava block, named “Dolphin,” which had emerged in the E part of the summit lava dome, was absent in an 8 December photo of the volcano. The Aviation colour Code remained at Orange (the second highest level on a four-colour scale).
Suwanosejima – Ryukyu Islands (Japan) : JMA reported nighttime incandescence and intermittent eruptive activity at Suwanosejima’s Ontake Crater during 4-11 December. A total of 20 explosions were recorded, ejecting bombs up to 500 m away from the crater and producing gray-and-white plumes that rose 1.5 km above the crater rim. Ashfall was reported in Toshima village (4 km SSW). The Alert Level remained at 2 (on a 5-level scale).
Villarrica – Chile : POVI reported that during an over-flight of Villarrica on 9 December scientists observed a small lava lake, 10-15 m in diameter, partially covered by floating black solidified lava. The Alert Level remained at Yellow, the second lowest level on a four-colour scale. ONEMI maintained an Alert Level Yellow (the middle level on a three-colour scale) for the municipalities of Villarrica, Pucón (16 km N), Curarrehue, and the commune of Panguipulli, and the exclusion zone of 500 m around the crater.

Human-made materials now outweigh Earth’s entire biomass
A research study has revealed that human-made materials outweighed the overall living biomass on Earth today.
The study, carried out by researchers to provide an objective measure of the reality of the balance between man and nature, estimated that the amount of plastic alone is greater in mass than all land animals and marine creatures combined.
Human activity including the production of concrete, metal, plastic, bricks and asphalt outweighs the overall living biomass on Earth, the study concluded.
A paper published in Nature stated that on average, each week, every person is responsible for the creation of human-made matter equal to more than their own bodyweight.
More Locusts
East African officials say weather conditions are now favorable for another wave of ravenous locusts to swarm across the region from the Red Sea to Kenya. The United Nations Food and Agriculture Organization also predicts fresh immature swarms will soon migrate southward to Ethiopia and Somalia before eventually invading northeastern Kenya.
These same areas were hit earlier this year by massive swarms that also originated around the Red Sea. Successive generations are still devouring grasslands, threatening food shortages and laying eggs.

An international team of researchers says it has found that a species of sparrow intentionally uses medicinal herbs to ensure the health of its offspring. Such behavior was earlier thought to be restricted to only a small number of animals, mainly higher primates.
William Feeney of Australia’s Griffith University says russet sparrows use wormwood leaves to build nests. “The phytochemical compounds within wormwood leaves reduced infestation of the nest parasites, which results in the production of healthier chicks,” said Feeney.
Writing in the journal Current Biology, he and colleagues say that the birds seek out those leaves and adjust how many are in their nests through their sense of smell.
Ray Scanning
Japanese scientists have proposed a novel way to map the ocean’s vast unexplored seabed by equipping stingrays and electric rays with ultrasonic pingers and tiny cameras to collect data. “Electric rays and stingrays are benthic animals, meaning that they spend most of their time swimming around the ocean floor in deep places,” said Yo Tanaka of the RIKEN Center for Biosystems Dynamics Research.
By placing cameras on rays and linking the timing of the recorded video to the timing and locations determined by the pingers, the researchers believe they can create accurate maps of the ocean floor. Tanaka says trial experiments confirm the scheme is practical.
Global Temperature Extremes
The week’s hottest temperature was 112 degrees Fahrenheit (44.4 degrees Celsius) in Boulia, Queensland, Australia.
The week’s coldest temperature was minus 65.0 degrees Fahrenheit (minus 53.9 degrees Celsius) in Oimyakon, Siberia.
Temperatures were tabulated from the more than 10,000 worldwide synoptic weather stations. The United Nations World Meteorological Organization sets the standards for weather observations, and provides a global telecommunications circuit for data distribution.

Roundup of Global Volcanic Activity – Ongoing Activity for the Week 2 December 2020 – 8 December 2020
Aira – Kyushu (Japan) : JMA reported that during 30 November-7 December incandescence from Minamidake Crater (at Aira Caldera’s Sakurajima volcano) was often visible nightly. An explosion on 2 December produced an eruption plume that rose 1 km above the crater rim and blended into weather clouds. Volcanic bombs were ejected 1-1.3 km away from the crater. That same day the sulfur dioxide emission rate was high, at 2,500 tons per day. During 4-7 December two eruption plumes rose as high as 1.2 km above the crater rim. The Alert Level remained at 3 (on a 5-level scale).
Dukono – Halmahera (Indonesia) : Based on satellite and wind model data, the Darwin VAAC reported that during 4-7 December ash plumes from Dukono rose to 2.1 km (7,000 ft) a.s.l. and drifted NE, E, and SE.

Nevado del Ruiz – Colombia : Servicio Geológico Colombiano’s (SGC) Observatorio Vulcanológico y Sismológico de Manizales reported that during 1-8 December seismicity at Nevado del Ruiz was generally characterized by higher number of earthquakes that had larger magnitudes than the previous week. Several episodes of drumbeat signals were recorded, indicating ascent or growth of a lava dome in Arenas Crater. Gas-and-ash emissions were sometimes visible in webcam images. Two thermal anomalies were visible in satellite data. The Alert Level remained at 3 (Yellow; the second lowest level on a four-colour scale).
Semeru – Eastern Java (Indonesia) : PVMBG reported that the eruption at Semeru continued during 1-8 December. Rock avalanches were recorded by the seismic network almost daily and were visible most days, traveling 200-1,500 m down the Kobokan drainage. Eruptive events and rockfalls generated pyroclastic flows that traveled as far as 2.5 km down the Kobokan drainage on the SE flank during 1-3 and 5-6 December. BNPB noted that deposits from the 1 December pyroclastic flow were as thick as 15 m. According to the Darwin VAAC, ash plumes rose to altitudes of 4-6.1 km (13,000-20,000 ft) a.s.l., or 300-2,400 m above the summit, and drifted E and NE during 2 and 5-6 December. PVMBG noted that incandescent material was ejected 50-100 m above the summit during 5-8 December.

Slovenia, Croatia – Heavy rains have battered parts of Slovenia and Croatia close to the Adriatic Sea coast, causing floods and landslides, blocking roads and disrupting traffic. Persistent rain in coastal Slovenia on Wednesday made the Dragonja river overflow its banks along the border with Croatia, blocking a key road in the area and forcing closure of a border crossing. A landslide brought down trees in the area of the port town of Koper and flooded regional roads, while rising Adriatic Sea waters submerged parts of nearby Piran.
