On August 27, thanks to images from ECU911, strong activity was observed at the Sangay volcano, with ash emissions and pyroclastic flows in the southeastern quebrada.

The wind carries the ash to the southwest, which could generate moderate ash fall in the province of Chimborazo.

This phenomenon has been persistent during the current eruptive period which began in May 2019.
