In Ecuador, in the past two months, Sangay has shown a sustained explosive activity, characterized by ballistic projections and lava flows (or pyroclastic) near the summit, thermal activity is detected by Mirova on the slopes within 5 km the summit.

These explosions and their eruptive plumes are visible from afar in climatic conditions and favorable visibility. Washington VAAC reported plumes of between 6.1 and 8.2 km on 4-7 and 9-10 May.

An overview of Cotopaxi on May 10 by the IGEPN and MAF helped to visualize the surface activity with a gas emission column of about 600 meters, not containing ashes. Glaciers are cracked and some covered with snowdrifts.

The control of temperature anomalies shows a slight decrease in temperature associated with fumaroles on the flanks, with for example 35.5 ° C max on the southern flank.

The trend is a moderate decline of domestic activity level.
