Updates on volcanic activity (Smithsonian)

The Smithsonian/USGS Weekly Volcanic Activity Report provides information about global volcanism on a weekly basis. Latest Sangay report has been published on 30 Sep 2020 09:19.
IG issued a report with additional information about the large explosive event at Sangay on 20 September. The event began at 0440 and ended at 0610 and produced an ash plume that rose 15 km (49,200 ft) a.s.l., or about 9.7 km above the summit. The lower part of the plume was the most ash-rich and drifted W, causing significant ashfall in areas W (especially in the Cebadas parish, Guamote district). The gas-rich higher part of the plume drifted E. Parts of the plume also drifted S. Researchers visited several sites to measure ashfall and collect samples, allowing them to estimate the volume of the deposits at 1.5-3.4 million cubic meters, signifying a VEI 2 event.
