LEGAZPI CITY, Albay – Six phreatic eruptions were recorded in Mayon Volcano on Wednesday, the Philippine Institute of Vol­canology and Seismology (Phivolcs) said.

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.
