The Chilean government declared an emergency alert and ordered a full evacuation of residents from a circle zone of an approximately 20 km radius from the crater. The volcanic plume rose up to about 15 km height and affected the flight cancellation. After the eruption, the GOSAT/TANSO-CAI observed the volcanic plume continuously.
