Ecuador's Geophysical Institute is reporting that Reventador is currently erupting ash. Apparently, there is no threat to nearby Quito or any pipelines near the volcano. The volcano last erupted in 2007 (although the article incorrectly reports 2002) with small VEI 2 explosions and lava flows. The last major eruption was in 2002, a VEI 4 that spread ash over Quito and caused a number of fatalities. The 2002 eruption was an impressive one (see picture above), producing numerous lahars and a 17-km tall (~55,000 feet) ash column. This also makes two currently erupting volcanoes in Ecuador with the ongoing activity at Tungurahua.
