Mayon Volcano raised to Alert Level 3
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) raised Mayon Volcano‘s alert level from 2 to 3 today, 8th June 2023, at 12pm.
As for the reason behind the heightened alert level, PHIVOLCS cites the increasing number and volume of rockfall from the volcano. This means that there is an “increased tendency towards a hazardous eruption”.

According to PHIVOLCS, rockfall events from the Mayon Volcano went from 54 on June 1-4 to 267 during June 5-8. There have also been 2 volcanic earthquakes recorded in the area.
Besides these, 3 pyroclastic density currents (PDCs) were observed today on the Bonga (southeast) and Basud (east) Gullies. A PDC is a fast-moving flow of hot volcanic materials that poses a significant threat to life and property.
Thankfully, sulfur dioxide emission remains at standard levels.
Possible eruption within weeks or days

With the increased volcanic activity, PHIVOLCS expects “potential explosive activity” from Mayon Volcano within weeks or days.
As such, the agency has asked residents within a 6km radius of the volcano to evacuate. Pilots are also advised against flying over the volcano.
Ash fall is expected to occur on the south side of Mayon Volcano based on the prevailing wind pattern.
