Reventador volcano (Ecuador) - Smithsonian / USGS Weekly Volcanic Activity Report for 4 April-10 April 2007 (New Activity / Unrest)

Mi, 4. Apr 2007, 06:00
06:00 AM | VON: VN
Incandescent blocks ejected from the summit of Reventador that subsequently rolled down the S flanks were observed at night during 3-4 April. Satellite imagery revealed ash plumes drifting W and a large thermal anomaly over the crater. On 4 April, a plume rose to an altitude of 4.6 km (15,100 ft) a.s.l.
Crater incandescence was observed on 4 and 6 April and "cannon shots" were heard on 6 April. Ash-and-steam emissions were observed during 8-9 April. Steam emissions from the flanks on 8 April possibly originated from a lava flow.

Reventador volcano (Ecuador), eruption news: new explosive activity

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. Read all
