The volcano's activity has remained high since the beginning of the current eruptive phase since 25 March. Fresh lava continues to extrude at the summit crater, adding to the dome that had been active since 2011, and producing incandescent avalanches, small pyroclastic flows on its flanks and ash emissions.
Current seismic signal from Reventador (CONE station, IGPEN)
Seismic activity has remained at high levels, showing continuous tremor and emissions signals. IGPEN reports that the pyroclastic flows on the E, SE and S flanks have traveled up to 1.5 km from the summit. Additionally, there seems to be at least 2 lava flows that descend the south-eastern and eastern flank of the volcano, with fronts reaching approx. 500 m distance.

The volcano has entered a new eruptive phase since yesterday, Ecuador's Institute of Geophysics (IGP) reported. Starting from 15:00 local time yesterday, increasing tremor was registered and steady ash emissions were observed. At night, incandescent blocks could be seen and heard rolling down from the crater where probably a new lava dome has started to appear. ... lire toutes

Intense degassing and occasional weak explosions with ash emissions probably continue, based on the more or less unchanged moderately intense seismic activity. Visual observations were not possible over the past days due to cloud cover. ... lire toutes

Activity at the volcano continues at moderate levels according to IG, but for the first time since a while, new ash emissions and incandescent material were reported. lire toutes

The activity consisting of sporadic small to moderate explosions continues but has decreased after 2 November. On that day, a small pyroclastic flow descended on the west flank of the active cone, reaching a length of 300-400 m. Explosions produced plumes of up to about 2 km height and light ash fall occurred in San Rafael village located 8 km east of the volcano. ... lire toutes
