Tungurahua volcano news & eruption updates:
Tungurahua volcano (Ecuador): decreasing activity, warning against mud flows
Tuesday Feb 25, 2014 17:16 PM | BY: T
Activity continues an overall decreasing trend. The volcano has occasional explosions and ash emissions, typically 4-5 per day, which cause light ash fall, mostly in Pillate, Tisaleo and El Manzano to the S and SW. In between such emissions, the volcano is calm. Seismic activity is still significant, but also seems to be decreasing, the latest IGPEN report mentions.
It also writes that the scenario of a return to more elevated activity in the near future (days to weeks) is less likely than a continued trend towards calm.
A significant hazard for the valleys radiating from the volcano remain lahars, as the expected heavy rainfalls in the coming weeks can remobilize the significant amounts of fresh loose deposits and turn onto dangerous mudflows (lahars).

Activity remains at moderate to high levels according to the Geophysical Institute (but is considerably lower than earlier this year). Occasional explosions produce ash plumes of approx 1-2 km height and light ash fall was reported from the Pillate sector yesterday. [more]

Overall, the volcano's visible activity has continued to decrease with fewer and weaker explosions, although seismic activity remains moderate to high. The strongest explosion in the past days was one yesterday evening that produced an ash column rising 3 km, a powerful cannon-shot explosion sound. Bombs fell around the crater at distances of 500 m.

After the major eruptions on 1 Feb, the volcano continued to produce frequent (comparably) smaller explosions of strombolian to vulcanian type, sometime causing small pyroclastic flows. Ash falls have been mainly affecting areas in Penipe, south of the volcano. During the past days, activity has been decreasing overall. ... [more]

Activity of the volcano remains intense, but the style of the eruption has changed towards near continuous ash emissions as opposed to discrete, but potentially much more violent explosions. The ash plume still rises up to 4 km above Tungurahua's summit at times. ... [more]
