The Kanlaon volcano in the Philippines erupted today (Dec. 9) at 3:03 p.m. local time, spouting an eruption column of up to 1.86 miles (3 kilometers) into the sky and triggering the evacuation of 87,000 people.

The Philippines' Institute of Volcanology and Seismology reported that the eruption triggered a pyroclastic density current—a scorching flow of ash, debris, and rocks capable of obliterating everything in its path.
