November 05, 2013 - WORLDWIDE VOLCANOES - The following constitutes the new activity, unrest and ongoing reports of volcanoes across the globe, courtesy of Volcano Discovery.
Klyuchevskoy (Kamchatka): Tremor and degassing have increased with respect to the last report from KVERT. A steam plume rises about 2 km above the crater and a thermal anomaly over the volcano is visible on satellite data. This suggests that some volcanic activity (perhaps strombolian) has resumed (or continues).
Etna (Sicily, Italy): While the summit craters have remained calm, seismic activity shows continuing unrest at the volcano. A number of relatively shallow earthquakes occurred this morning under the volcano.
The only quake located by an international agency was a 2.9 magnitude event at 05:30 (GMT) at 18 km depth under the SW flank, while the other earthquakes were too small to be included, but appear to be shallower. More precise data will hopefully be available soon from INGV Catania.
Bagana (Bougainville Island, Papua New Guinea): A relatively large SO2 plume from the volcano today indicates a surge in activity (ash explosions, strombolian activity?).
Manam (Papua New Guinea): Elevated SO2 emissions are visible today on NOAA satellite data.
White Island (New Zealand): No further eruptive activity has occurred since the moderate eruption on the evening of 11 October 2013. Seismic activity and gas flux from the volcano have been at a low level since the eruption. The Aviation Colour Code has been lowered from Yellow to Green. (GeoNet).
Fuego (Guatemala): The volcano observatory of INSIVUMEH reports an increase in activity today: A new lava flow started to descend on the southern flank towards the Trinidad canyon and currently has a length of 100 m. Another branch towards the Ceniza canyon is 50 m long. From both flow fronts, incandescent avalanches detach with run-out lengths of up to 500 m.
The risk of pyroclastic flows triggered by collapse of the steep lava flow fronts is elevated.
Accompanied by elevated seismic activity, more and stronger explosions have occurred today. Ash plumes rose up to 800 m height above the crater and often produced loud shock waves that rattled roofs and windows of houses in villages Panimaché, Morelia and Panimaché II.
There are constant degassing sounds similar to a locomotive, and incandescent material is ejected to heights of 125-200 meters above the crater, generating avalanches on the upper slopes.
