Global volcano activity:

Earthquake activity in or near the upper eastern rift zone of Kilauea volcano on Hawaii has been increasing. A magnitude 3 quake occurred in the northern part of the caldera today. Lava flows southeast of Pu`u `O`o continued to be weakly active on the coastal plain.

Popocatépetl in Mexico has been decreasing again after rising over the past week. During 27-28 Oct, there was only about 1 emission per hour. A few of them produced small ash plumes.

Fuego volcano in Guatemala has a few weak explosions and continues to alimentate the lava flow towards the Ash Canyon which is now about 400 m long.

Few weak ash explosions occur from the Santiaguito lava dome and the block lava flows from its summit vent remain weakly active - Guatemala.

Occasional small ash eruptions continue to occur at Galeras volcano in Colombia, such as today.

A thermal hotspot can still be seen at Michael volcano in the South Sandwich Islands.

In the past days Sakurajima volcano in Japan returned to average levels of activity and produced 1-2 mild explosions per day.

Global volcanic activity:

Popocatépetl's activity in Mexico remains stable with about 2 weak explosions per hour. Most of these only produce steam plumes, only the stronger ones are accompanied by weak ash plumes. Crater glow is visible at night and a significant SO2 emission indicates that magma continues to rise in the volcano.

Explosive activity from Fuego volcano, Guatemala is increasing in favor of effusive. Since yesterday, there have been 13 weak to moderate explosions with ash rising up to 1000 m. The lava flow towards the Ash Canyon is still active and now 400 m long.

A mild ash explosion from the Santiaguito lava dome [Guatemala] occurred this morning with a weak plume rising to 3100 m altitude. Activity otherwise remains mainly effusive. The thick block lava flows that descend from the summit are still weakly active and produce avalanches of rocks detaching from their fronts.

Heavy rainfalls around Tungurahua volcano in Ecuador triggered lahars one of which damaged the Baños-Penipe road.

The seismic swarm in the Tjörnes Fracture Zone north off Iceland continues and the Icelandic Civil protection issued warning about the possibility of a larger earthquake.

Global volcanic activity:

Within the past few days, the lava lake at Kilauea volcano on Hawai'i within Halema‘uma‘u crater has risen to a record levels. 1 year ago the lake was 70m/230ft deep, 1 month ago it was 60m/200ft deep, 1 week ago it was 50m/165ft deep, and today it sits only 33m/110ft deep!

Elevated surface temperatures were detected at Cleveland volcano in Kamchatka on 19 and 22 October, this may be related to a period of lava dome growth at the volcano.

Lokon volcano in North Sulawesi erupted again on Saturday (20/10/2012) at around 01:33 am in the morning. According to a news article, ejecta were seen rising 400 m from the observatory and the eruption lasted for about 70 seconds.

Paluweh volcano (Rokatenda) volcano on Flores (Indonesia) is still showing some activity. A Modis satellite image taken on Monday, 22 October showed a gas plume containing ash drifting 80 KM west of the volcano.

Popocatépetl's activity in Mexico has decreased again. During 22-23 Oct, 39 small explosions, some with weak ash plumes, were recorded. Crater glow is still visible at night, and some small earthquakes continue under the volcano.

The lava flow from Fuego volcano is decreasing and now only 600 m long. As effusive activity weakens, more explosions seem to occur. INSIVUMEH counted 6 weak events during 22-23 Oct with ash plumes rising about 500 m.

Seismic activity remains elevated at Sotará volcano in Colombia and INGEOMINAS keeps a close watch on the volcano. A swarm on 17 Oct contained over 700 small quakes.

The seismic swarm in the Tjörnes Fracture Zone north off Iceland continues at reduced rate. According to the Icelandic Meteorological Office, there is enough stress to produce a magnitude 6.8 earthquake, but it is impossible to predict if and when such a quake might occur.
