Tungurahua volcano (Ecuador): new ash emissions, eruption warning
Wednesday Apr 08, 2015 09:38 AM | DOOR: T
The volcano entered a phase of increasing activity again. New ash emissions, tremor episodes and increased SO2 output occurred during the past days and suggest that a new pulse of magma is on its way. This could lead to a new, possibly intense eruptive phase in the near future.

Because the last significant activity occurred more than 6 months ago, the upper conduit of the volcano is likely blocked by a plug under which pressurized gasses accumulate. This in turn could lead to a sudden, strong vent-clearing explosion, a potentially very dangerous eruption.
The first signs of new unrest at Tungurahua had already been noted in February this year, when seismicity increased and a small eruption occurred on 19 Feb. The earthquakes had afterwards decreased again, but a new pulse started 3 days ago.
Starting 03h56 local time on 6 April, a volcanic tremor signal associated with ash emissions occurred in the sectors of Chacauco and Manzano and in the area of Alto Punzupal. A strong smell of sulfur was also noted west of the volcano.
