Mayon Volcano’s (13.2576 N, 123.6856 E) seismic network recorded 3 volcanic earthquakes and 13 rockfall events related to the detachment of lava fragments at the volcano’s upper slopes during the past 24 hours.  Steaming activity and crater glow were not observed due to thick clouds that covered the summit crater. Sulfur Dioxide (SO2)  emission rate was measured yesterday at

an average of 635 tonnes/day.

Alert Level 2 is in effect over Mayon Volcano. This means a further reduction in the likelihood of hazardous eruption. PHIVOLCS-DOST recommends that the public should not enter the six (6) kilometer radius Permanent Danger Zone and the 7-km Extended Danger Zone on the southeast of the volcano due to continuing threat from sudden explosions, rockfalls from the upper slopes and pyroclastic flows due to sudden collapse of unstable lava deposits. Active river channels and those perennially identified as lahar prone in the southern sector should also be avoided especially during bad weather conditions or when there is heavy and prolonged rainfall. PHIVOLCS-DOST is closely monitoring Mayon Volcano’s activity and any new development will be immediately posted to all concerned.
