The Philippine Institute of Volcanology and Seismology (PHIVOLCS) said in its 8 a.m. bulletin on Sunday that it recorded "sporadic and weak lava fountaining" events in Mayon on Saturday, which lasted for 37 seconds.

PHIVOLCS said the volcano also released a 500-meter high ash plume.

"Throughout the night, quiet lava effusion fed lava flows in the Miisi and Bonga-Buyuan channels and barrancos between these. The Miisi and Bonga-Buyuan lava flows have advanced to 3.2 kilometers and 4.3 kilometers, respectively, from the summit crater," PHIVOLCS said in its bulletin.

Mayon's seismic monitoring network has recorded a total of 55 volcanic earthquakes, most of which corresponded to sporadic and weak fountaining events, and nine rockfall events.

It also measured an average of 1,583 tonnes per day of sulfur dioxide gas emission on Friday.

PHIVOLCS officer-in-charge Renato Solidum Jr. said that a lower gas output does "not really" equate to Mayon "calming down."

Alert Level 4, the second highest alert level, remains in effect over Mayon as hazardous eruption remains imminent. —Marlly Rome Bondoc/ALG, GMA News
