Reventador volcano, Ecuador: news & activity updates

Reventador volcano (Ecuador): activity summary 7-13 Nov - growing lava dome and lava flows

Thursday Nov 15, 2012 06:26 AM | DOOR: T

A new phase of activity started on 9 November, characterized by lava flows from the crater, steam plumes, and thermal anomalies detected in satellite images.
The lava flows traveled as far as 2 km down the N and S flanks, and steam plumes rose 200-500 m above the crater. Field visits by volcanologists in recent months confirmed that the lava dome in the crater had continued to grow above the rim, becoming the highest point of the volcano. Blocks from the lava dome and lava-flow fronts rolled down the flanks.
IG noted that during 3-4 November emissions increased; a steam-and-ash plume rose 3 km above the crater. The seismic network detected an increase in the magnitude of volcanic tremor. Steam-and-gas plumes contained ash within the previous few days.
