Sangay volcano (Ecuador) - Smithsonian / USGS Weekly Volcanic Activity Report for 5 January-11 January 2022 (Continuing Activity)
IG staff observed Sangay during an overflight on 27 December 2021, focusing on the summit area along with the SE and NE flanks. Two vents were active in the summit area, a central vent and a western vent in a scoria cone. The central vent produced Strombolian explosions and had temperatures as high as 645 degrees Celsius.

Lava from this vent fed a flow on the SE flank that was 540 m long; the maximum temperature of the flow was 580 degrees. The W vent ejected blocks and gas emissions, and had temperatures as high as 410 degrees. The third vent, on the NE flank, produced gas emissions and temperatures above 515 degrees.
A lava flow from this vent had descended 370 m and was as hot as 450 degrees. The team took gas measurements around the summit with a MultiGAS instrument, collected ash samples, and acquired data and conducted maintenance at the SAGA monitoring station, 6 km SW of the summit.
