MANILA, Philippines — At least four volcanic quakes were recorded on Mayon Volcano in Albay province in the last 24 hours, the Philippine Institute of Volcanology and Seismology (Phivolcs) said Friday.
In its latest bulletin, Phivolcs said two of these earthquakes were related to phreatic blasts recorded at 8:17 a.m. and 8:25 a.m. Thursday.
Mayon Volcano belched out grayish to grayish-white ash plumes that rose 600 meters and 200 meters above the summit twice on Thursday morning.
Phivolcs said the explosions were triggered by a steam pressure that developed underneath the volcano’s vent.

“Alert Level 2 currently prevails over Mayon Volcano. This means that Mayon is at a moderate level of unrest,” Phivolcs said.
The Phivolcs reminded the public that sudden explosions, lava collapses, pyroclastic density currents and ashfall could still occur and threaten areas in the upper to middle slopes of Mayon. /cbb
