Reventador volcano (Ecuador) - Smithsonian / USGS Weekly Volcanic Activity Report for 3 September-9 September 2014 (Continuing Activity)

Ср, 3 сен 2014, 06:00
During 3-9 September IG reported moderate activity including explosions, long-period earthquakes, harmonic tremor, and tremor at Reventador. While cloud cover frequently limited observations, on 5-8 September steam emissions were observed with small quantities of ash. In the morning of 5 September an explosion generated a plume and ejected blocks from the crater that fell ~500 m below the summit on the W flank.
A thermal camera detected an explosion on the following day that also included ballistics. Rumbling sounds were heard in the morning of 7 September, and that evening a 1 km plume was observed. The following morning a vapor plume persisted from the summit, and in the afternoon it contained a small amount of ash.

The MODIS sensor onboard the Terra satellite detected thermal anomalies from the region of Reventador's summit during 4-6 September.
