Current seismic signal from Tungurahua (RETU station, IG)
The volcano continues to be restless with moderate seismic activity. Short emissions occurred occasionally during the past days, but most of them were inferred by seismic signals and could not be observed directly due to cloud cover.
Minor ashfall was reported in El Manzano (8 km SW) and Cahuaji on 26 March. Seismicity was at moderate levels and then declined during 28 March-1 April. Lahars on 31 March traveled down the Vascún (N) and Mapayacu (SW) drainages, carrying blocks up to 1 m in diameter in the latter drainage (from the latest Smithsonian / USGS Weekly Volcanic Activity Report).

The volcano had a short burst of activity on 26 Feb, producing a series of moderate explosions and small pyroclastic flows reaching up to 400 m on the northern and northwestern flanks.

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. ... [more]
