PHIVOLCS: 7 rockfall events, sulfur dioxide emission monitored at Mayon but no magmatic eruption imminent

(Eagle News) — Seven rockfall events were monitored at Mayon in 24 hours.

The Philippine Institute of Volcanology and Seismology said sulfur dioxide emission was also monitored at the volcano, which remains on alert level 1.

PHIVOLCS said sulfur dioxide emission was last measured at an average of 676 tons on December 29.

“Overall, the Mayon edifice is still inflated with respect to baseline parameters,” PHIVOLCS said.

PHIVOLCS said that while no magmatic eruption was imminent, at alert level 1, the volcano is “at an abnormal condition.”

It urged the public to refrain from entering the 6-kilometer radius Permanent Danger Zone.

Active stream and river channels and those identified as perennially lahar-prone areas should be avoided.

“DOST-PHIVOLCS maintains its close monitoring of Mayon Volcano and any new development will be communicated to all concerned stakeholders,” PHIVOLCS said.
