Tungurahua volcano (Ecuador): powerful vulcanian explosion, ash to 10-15 km altitude

Eruption of Tungurahua on 4 April 18:10 (F. Vásconez - OVT/IGEPN)
The volcano entered a new vigorous eruptive phase yesterday evening. A moderately strong vulcanian explosion occurred at 18:10 (local time) and produced an eruption column rising several kilometers as well as small pyroclastic flows on the cone.
Current seismic signal from Tungurahua (RETU station, IG)
The eruption plume (originally estimated to have reached up to 50,000 ft / 15 km altitude, but probably much lower than that) drifted to westerly directions. Ash / lapilli fall with 1-3 cm diameter clasts occurred in the areas of Bilbao, Choglontus, Chacauco and Cusúa.
The explosion, which likely cleared the conduit from a solid plug was followed by frequent, smaller explosions accompanied by a constant tremor signal of high energy. When the volcano was not hidden in clouds, the expulsion of incandescent blocks that rolled down the upper flanks, and steam-gas-ash emissions could be observed. Individual stronger explosions also occurred intermittently, some of which rattled the windows and doors of the Tungurahua Volcano Observatory (OVT), located 14 Km northwest.
Related explosion 18:10 (local time) have received reports of falling rubble (lapilli)

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. read all

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. Ash plumes rose up to 2.5 km above the crater. Since then, the volcano has been mostly quiet and only had minor emissions. read all

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. ... read all
