Reventador volcano (Ecuador) - Smithsonian / USGS Weekly Volcanic Activity Report for 4 January-10 January 2012 (New Activity / Unrest)
IG reported that staff conducting fieldwork at Reventador during 6-7 January observed constant emissions of gas-and-steam rising about 300 m above the crater and drifting WNW. The emissions originated from a growing lava dome that was a few tens of meters above the crater rim and almost filled the base.

Reventador volcano (Ecuador) - Smithsonian / USGS Weekly Volcanic Activity Report for 5 January-11 January 2011 (Continuing Activity)
Based on a pilot observation, the Washington VAAC reported that on 4 January an ash plume from Reventador rose to an altitude of 5.2 km (17,000 ft) a.s.l. Cloud cover prevented clear satellite observations of the volcano. A subsequent report stated that IG noted low seismicity, no reports of ashfall, and that satellite imagery showed no ash emissions. ... Read all
