Reventador volcano, Ecuador: news & activity updates
Reventador volcano (Ecuador), activity update: small ash eruption on 11 Oct
Infrequent, mostly small ash eruptions continue at Reventarod volcano. On 11 October, the volcano produced an ash plume that rose to an altitude of 4.6 km (15,000 ft) a.s.l. and drifted S.
On 28 March, an eruption from Reventador produced an ash plume that rose to an altitude of 5.6 km (18,400 ft) a.s.l. and drifted W. A small lava flow traveled 200 m down the S flank. Incandescent material and ash emissions were observed during 29-31 March. On 1 April, ash plumes rose to an altitude of 7.6 km (24,900 ft) a.s.l. and incandescent rocks were ejected about 50 m above the crater. Incandescent material was again seen at the summit on 2 April. The
Washington VAAC reported that a strong hotspot was present on satellite imagery during 1-3 April. Based on pilot reports, IG reported that a steam-and-gas plume with little ash content rose to an altitude of 6.1 km (20,000 ft) a.s.l. and drifted W on 3 April.
New activity has started at Reventador volcano. In early March, the number of tectonic earthquakes from Reventador had increased. During 8-22 March, steam-and-ash plumes rising to altitudes of 4 km (13,000 ft) a.s.l. were observed sporadically.
On 21 March, noises were reported. The next day, seismic signals changed and indicated possible emissions. On 24 March, local people saw ash plumes and incandescent material near the crater and heard roaring noises. An explosion produced a plume that rose to an altitude of 6.6 km (21,700 ft) a.s.l. and drifted W. Based on reports from IG, the Washington VAAC reported an ash plume to altitudes of 3.7-7 km (12,000-23,000 ft) a.s.l. that drifted NE and WNW during 26-27 March. A thermal anomaly was present on satellite imagery during 24-27 March.

The eruptions at Reventador volcano in Ecuador's eastern cordillera continues into early July with the emission of overlapping, thick blocky lava flows, occasional vulcanian explosions, new fumarolic activity on the N flank of the cone, and the emission of steam, gas and ash.... [more]
Reventador Volcano in Ecuador has started to erupt again on Tuesday. According to Hugo Yepez, director of Geophysics Institute of the National Polytechnical School (IGEPN), a lava flow inside the crater has appeared. There is an increased possibility of explosive events in the near future.
Reventador, 3,485 meters high, is a symmetrical stratovolcano that had a major explosion on November 3, 2002, when a thick layer of ash reached the capital Quito.
