Phivolcs logs 256 rockfall events at Mayon Volcano
MANILA, Philippines — State volcanologists recorded 256 rockfalls amid ongoing lava flow at Mayon Volcano, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
In its latest observation at 12 a.m. Sunday, January 11, Phivolcs reported that Mayon Volcano in Albay also generated 41 pyroclastic density currents, along with the 256 recorded rockfall events.
The sulfur dioxide flux emitted also reached 777 metric tons per day on January 10. This was further corroborated by ground deformation data, which indicate that the volcano remains swollen or inflated.
Meanwhile, the volcano continues to emit moderate steam plumes reaching up to 200 meters, drifting toward the northeast, according to Phivolcs.
As of writing, Mayon Volcano remains under Alert Level 3, which has been in effect since January 6.
Authorities continue to enforce a strict ban on entry into the six-kilometer Permanent Danger Zone due to the constant threat of rockfalls, avalanches and explosions.
