The eruption status was raised from an alert to standby 4 kilometers (2.5 miles) from the summit and up to 6.5 kilometers to the west-southwest. Standby status means people should avoid the area nearest the volcano and have masks available in the event of ashfall.

Planes were warned of the ash clouds because volcanic ash is hazardous for plane engines.
