Mayon Bulletin | Jan. 21 (8 am)

According to the 8:00 AM bulletin of Mayon Volcano today,  ten (10) volcanic earthquakes were recorded during the 24-hour observation period.

And, moderate emission of white steam-laden plumes that crept downslope before drifting to the general north was observed.

Furthermore, a faint crater glow from the summit could be observed at night.

Alert Level  1

The volcano is on Alert Level 1 or abnormal condition, and the agency is reminding everyone with the following:

• Presently no magmatic eruption is imminent, it is strongly advised that the public refrain from entering the 6-kilometer radius Permanent Danger Zone (PDZ) due to the perennial life-threatening dangers of:
  • rockfalls
  • landslides/avalanches at the middle to upper slope
  • sudden ash puffs
  • steam-driven or phreatic eruptions from the summit.
• Active stream/river channels and those identified as perennially lahar-prone areas on all sectors of the volcano should also be avoided especially during extreme weather conditions when there is heavy and prolonged rainfall.
