Small ash puff from Reventador today
Effusive-explosive activity continues at the volcano. Small ash eruptions occurred today and weak lava effusion on the upper flanks of the cone can be seen on thermal webcam imagery.

IG reported that although cloud cover often prevented observations of Reventador, during 18-24 June ash plumes were occasionally observed. At night on 17 June incandescence was observed on the S and E flanks. In the morning of 18 June a diffuse ash plume was visible rising ~600 m above the summit that dispersed to the NW.

Ash explosion at Reventador today (IGPEN webcam)
A moderate explosion at the volcano produced an ash plume that rose to flight level 210 (21,000 ft / 6.5 km altitude), a pilot reported.

Current seismic signal at Reventador (CONE station, IGPEN)
Weak to moderate effusive and explosive activity continues at the volcano. Cloud cover prevents direct observations most of the time, but the seismic signal shows tremor and explosion signals. A thermal hot spot indicates that lava continues to build up at the summit lava dome.

IG reported that although cloud cover often prevented observations of Reventador during 21-27 May ash plumes were occasionally observed. An ash plume was observed from an aircraft on 22 May, and the next day an ash-and-vapor plume rose 1 km and drifted NW.

The lava flows on the slopes of the summit cone are no longer active, but intermittent explosions of small to medium size continue to occur.

Current infrared image of Reventador volcano showing the still active (white) / cooling (yellow) lava flows (IGPEN)
The activity of the volcano had increased during the past two weeks, producing several lava flows and some relatively strong explosions. At the moment, it has decreased again, but remains moderately high. Explosions have become less frequent and the lava flows are only weakly alimented.

IG reported that a small pyroclastic flow traveled a few meters below Reventador's crater on 29 April. Cloud cover occasionally prevented visual observations during 30 April-6 May. An ash plume rose 3-4 km and drifted W on 1 May, and a steam plume with some ash rose less than 1 km the next day.

MODIS hot spot at Reventador (MODVOLC, Univ. Hawaii)
The volcano continues to produce small to medium explosions with ash plumes rising up to 1.5 km. A MODIS hot spot indicates the presence of fresh lava at the summit, but there seems to be currently no lava flow.

IG reported that activity at Reventador remained high on 9-15 April; numerous explosions were detected each day. Steam-and-ash plumes rose less than 1 km above the crater and drifted W during 9-10 April. Lava flows down the SW flank were reported on 9 and 11 April.

Explosion at Reventador Monday evening
Activity remains high. The volcano produces frequent small ash explosions and lava extrudes in a new flow on the upper eastern flank.

IG reported that cloud cover occasionally prevented visual observations of Reventador during 2-8 April; activity remained high. A steam-and-ash plume rose 3 km and drifted E on 2 April, and a thermal camera detected hot material on the flanks. Four lava flows on the S and SE flanks were observed on 3 April.

MODIS hot spot data (past 7 days) for Reventador volcano (ModVolc, Univ. Hawaii)
Activity at the volcano remains elevated, although no direct observations were possible in the last days due to cloud cover. A lava flow might be descending from the new dome on the eastern side, various reports suggests.

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.

Continuous ash emission and incandescent avalanches on Reventador's eastern flank (image: G. Taipe / IGP)
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.

IG reported that activity at Reventador increased on 25 March. At 1830 an explosion was followed by a pyroclastic flow that traveled 500 m down the flanks. Strombolian activity produced gas-and-ash plumes that rose 1.5 km above the crater.

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.

Based on information from IG, the Washington VAAC reported that on 22 January an ash plume from Reventador rose to an altitude of km (12,000 ft) a.s.l. Ash was not identified in satellite images. IG noted that an explosions lasting several minutes was recorded.

Based on a pilot observation, the Washington VAAC reported that on 31 December an ash plume from Reventador rose to an altitude of km (16,000 ft) a.s.l. Ash was not identified in satellite images due to weather clouds in the area but an occasional thermal anomaly was detected.
