Activity at Mayon Volcano in Albay province continues, with 279 volcanic earthquakes recorded in a 24-hour period as of Sunday morning, according to the Philippine Institute of Volcanology and Seismology.
Increased Volcanic Activity
In addition to the earthquakes observed on Saturday, state seismologists also reported 324 rockfalls and three pyroclastic density current signals. The alert level remains at 3.
Lava effusions and episodic minor strombolian activity are ongoing. A total of 2,430 tonnes of sulfur dioxide flux was also observed. On Saturday, the crater glow was described as “fair” and the plume was “obscured.”
Potential Hazards
Authorities continue to prohibit entry into the six-kilometer radius Permanent Danger Zone and advise aircraft to avoid flying close to the volcano. Possible hazards include rockfalls, landslides, avalanches, ballistic fragments, lava flows, lava fountaining, pyroclastic density currents, moderate-sized explosions, and lahars during heavy or prolonged rainfall.
The current situation may continue with similar levels of activity, potentially leading to further rockfalls or small explosions. It is also possible that the intensity of the eruption could increase, though this cannot be predicted with certainty based on the available information. A prolonged period of heavy rainfall could also trigger lahars, posing a threat to areas downstream.
