LEGAZPI CITY, Albay – Six phreatic eruptions were recorded in Mayon Volcano on Wednesday, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
In its latest advisory, Phivolcs said that the series of phreatic eruptions were recorded at 9:06 a.m, 9:39 p.m., 9:46 p.m., 9:55 pm., 10:00 p.m., and 10:59 p.m.
The ash plume generated from these events rose 200 meters, 500 meters, 200 meters, 500 meters, 700 meters, and 300 meters above the summit, respectively, before drifting west, according to Phivolcs.
Six volcanic earthquakes and three rockfall events were recorded by Mayon Volcanic’s seismic monitoring network during the 24-hour observation.
Senior Science Research Specialist of Phivolcs, Paul Alanis said that the successive eruptions do not mean they will raise the alert level.
“No raising of alert level. Normally, pag alert level 2, we expect na magkakaroon ng mga phreatic eruptions,” he said.
Phivolcs reminds the public that sudden explosions, lava collapses, pyroclastic density currents (PDCs) and ashfall can still occur and threaten areas in the upper to middle slopes of Mayon while entry to the six kilometer-radius PDZ remains prohibited.
