Tungurahua volcano (Ecuador): increasing activity, explosions
Thursday Aug 27, 2015 06:57 AM | BY: T
Activity at the volcano increased since Tuesday (25 Aug), the volcano observatory reported.
Seismogram of Tungurahua's BMAS station showing the tremor that began at 03h05 (TL) and was followed by five explosions (05h57, 06h26, 07h02, 07h52 and 09h44)
From 03:05 local time, seismic activity increased with the appearance of tremor accompanying ash emissions. Black, hence likely juvenile (from fresh magma) ash fell on Chontapamba Pillate, Bilbao and Juive Grande is recorded. Subsequently, 5 explosions were recorded starting at 05:57. The intensity of these increased progressively, the strongest occurring at 08:05.
Ash plumes rose to approx. 2 km above the volcano's summit and drifted west.
IGEPN warns that a further increase in activity could likely lead to strong explosions with associated pyroclastic flows.

New ash explosions took place at the volcano the day before yesterday (3 July), generating a plume that rose approx. 1 km above the summit and caused light ash fall on the western slope. ... [more]

Intermittent small explosions and ash emissions continue to occur from the volcano. However, its overall activity has been decreasing during the past weeks and the scenario of a larger eruption, which had been expected in early April, has been becoming more unlikely now. ... [more]

Over the past week, activity has remained at moderate levels with small to medium-sized ash emissions, but no larger explosions so far. The largest occurred on the afternoon of 15 April, when ash plumes rose to up to 3 km above the volcano. [more]

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. ... [more]
