In the past 24 hours, Mayon Volcano has experienced an increase in seismic activity within the volcano with 4 volcanic earthquakes, 307 rockfall events, and 13 pyroclastic density current events.
In its bulletin issued at 8 AM, the Philippine Institute of Volcanology and Seismology (Phivolcs) observed the lava flows have extended to approximately 1 kilometer away from the summit crater, while the collapse debris has reached a distance of 2 kilometers from the crater.
Additionally, a fair glow from the crater indicates the slow effusion of lava from the summit.
Sulfur Dioxide Flux measurements reached 826 tonnes per day on June 15, indicating the release of gases associated with magmatic activity.
The volcanic plume, rising to a height of 750 meters, has been drifting generally west and north-northeast.
Meanwhile, the ground deformation suggests that the volcano's edifice is currently undergoing inflation.
As a result, Mayon Volcano remains under Alert Level 3, signifying a relatively high level of unrest with magma present in the crater, increasing the possibility of a hazardous eruption within weeks or even days.
Authorities strongly advise against entering the 6-kilometer radius Permanent Danger Zone and flying aircraft near the volcano due to potential hazards.
Rockfalls, ballistic fragments, lava flows, pyroclastic density currents, moderate-sized explosions, and lahars during heavy rainfall are among the possible dangers.
Vigilance and adherence to safety guidelines are crucial during this period of heightened unrest.
Continuous monitoring and timely updates will be provided to ensure the safety of the public.
