Sabancaya (Peru) - Report for 1 July-7 July 2020

Instituto Geológico Minero y Metalúrgico (INGEMMET) reported that drone footage acquired at Sabancaya on 20 June showed that the lava dome in the main crater had been destroyed, leaving blocks on the crater floor.
Explosions at fractured areas generated gas-and-ash plumes.
During 23-24 June explosions produced gas-and-ash plumes that rose as high as 1.8 km above the summit and drifted E and SE.
Ashfall was reported in areas downwind including in the districts of Chivay, Achoma, Ichupampa, Yanque, and Coporaque, and in the area of Sallali.
Instituto Geofísico del Perú (IGP) reported a daily average of 20 explosions during 29 June-5 July.
Gas-and-ash plumes rose as high as 3.5 km above the summit and drifted S, SE, NE, and N.
There were seven thermal anomalies over the crater identified in satellite data.
The Alert Level remained at Orange (the second highest level on a four-color scale) and the public were warned to stay outside of a 12-km radius.
