Reventador volcano (Ecuador) - Smithsonian / USGS Weekly Volcanic Activity Report for 11 April-17 April 2007 (New Activity / Unrest)
On 11 April, a steam plume from Reventador rose to an altitude of 3.8 km (12,500 ft) a.s.l. Visual observations were hindered during 12-17 April due to inclement weather. On 13 April, the lava flow on the S flank, first observed on 28 March, was 15 m thick and possibly active.

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. Read all

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