Twenty-four volcanic earthquakes and 257 rockfall events were recorded in Mayon Volcano over the past 24 hours, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said Sunday.

The restive volcano in Albay also had 16 dome-collapse pyroclastic density current events and emitted a “moderate” 600 meter-tall of plume which drifted west-southwest and southwest from 5 a.m. Saturday to 5 a.m. Sunday, PHIVOLCS said in its bulletin.

It also continued to have a “very slow” effusion of lava flow, measuring 1.3 kilometers along the Mi-isi Gully and 1.2 kilometers along the Boga Gully.
