Mayon Volcano logs 7 quakes, remains on Alert Level 3

Mayon Volcano recorded seven volcanic earthquakes in the past 24 hours, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said Saturday.

Still at Alert Level 3, indicating magmatic unrest, the volcano registered 308 rockfall signals and 18 pyroclastic density current events.

It also emitted a 700-meter-high ash plume toward the southwest and showed ongoing lava-collapse pyroclastic flows as of 2:10 p.m. Friday.

The volcano’s edifice remains inflated, and sulfur dioxide emissions were measured at 2,003 tonnes per day, according to PHIVOLCS.

In an interview with dZbb, PHIVOLCS chief Teresito Bacolcol said the effusive eruption is continuing.

“We do not see any decline. We also do not see worsening,” he noted.

PHIVOLCS expects volcanic activity at Mayon to continue in the coming weeks and warned the public about hazards including rockfalls, landslides, avalanches, ballistic fragments, lava fountaining, pyroclastic density currents, moderate explosions, and lahars during heavy or prolonged rainfall.

Entry into Mayon Volcano’s six-kilometer-radius Permanent Danger Zone is prohibited, and aircraft are advised to avoid flying near the volcano.
