Phivolcs noted that ash emissions lasted 10 to 47 minutes, reaching as high as 500 meters with a west and west-southwest drift.

"This event generated grayish plumes that rose 500 meters above the crater before drifting west as recorded in the Mansalanao La Castellana station and Kanlaon Volcano Observatory in Canlaon City," the agency said.

Phivolcs measured the release of sulfur dioxide to be at 5,640 tons per day. Its observations centers recorded at least 22 volcanic earthquakes over a 24-hour period.
