Mayon Volcano alert raised
LEGAZPI CITY, Philippines—The alert level over Mayon Volcano has been raised to 2 from 1, the Philippine Institute of Volcanology and Seismology said Friday.
Volcanologist Alex Baloloy, who is based in Lignon Hill Observatory here, confirmed, in a text message, that the alert level has been raised to 2 as of 1 p.m.
Alert level 2 means the volcano is in a state of “moderate unrest” compared to alert level 1 which means a state of “abnormal condition.”
The new alert level has yet to be posted on Phivolcs’ website but its 8 a.m. bulletin when the volcano was still at alert level 1 showed no crater glow was observed over the volcano last night.
Sulfur dioxide (SO2) flux was measured at an average of 850 tons per day on Monday.
