Roundup of Global Volcanic Activity

Stromboli (Eolian Islands, Italy): The lava effusion continues at reduced rate, feeding an active flow on the upper part of the Sciara del Fuoco west of the previous main flow. Small explosive events continue to occur from the summit vents.

Bardarbunga (Iceland): The fissure eruption at Holuhraun continues, although it appears that only the main fissure is still producing lava fountains and flows, while the smaller fissures south of it became inactive and only emitted steam yesterday. The intensity of the eruption, i.e. the average output of lava, seems to be stable. Lava flows have been reaching the waters of Jökulsá á Fjöllum river, without producing explosive activity, only steam. The lava flows now cover almost 20 square km.

Zhupanovsky (Kamchatka, Russia): Ash emissions from the volcano have increased. Yesterday morning, VAAC Tokyo reported ash plumes that rose to 8-11 km altitude and drifted south and were visible on satellite images. Today, new, but smaller emissions were reported with plume heights of 3-4 km. The aviation alert level was raised to orange.

Kilauea (Hawai'i): The latest updates from authorities show no significant change in the path of the lava flow, only advancement through the jungle away from houses, for now. The flow has advanced relatively quickly covering roughly 1/2 mile (3/4 km) in the past 2 days, but typically that rate is hard to sustain for long. Between the six days of Aug 6-12, the map shows the flow made about 1 mi forward progress, but during the next six days the flow advanced only half that distance, totaling 1.5 mi (2 km) in 12 days.

Ubinas (Peru): Activity at the volcano has been low during the past weeks. Intense steaming and occasional small ash emissions have been reported. However, sudden larger explosions such as the one on 21 Aug, could still occur any time.
