A total of 102 volcanic earthquakes and 263 rockfall events have been logged in Mayon Volcano as it remains under Alert level 3 for almost three weeks now, the Philippine Institute of Volcanology and Seismology (Phivolcs) said on Monday.

In its monitoring from 5 AM on June 25 to 5 AM on June 26, Phivolcs said the country’s active volcano also emitted 8 dome-collapse pyroclastic density current (PDC) events with 3 minutes long and 925 tonnes of sulfur dioxide flux.

A steaming plume, produced by the Mayon Volcano’s continuous moderate degassing, rose to 100 meters before it drifted to the general west.

The restive volcano also continues to effuse fiery lava flows which reached 1,300 meters along Mi-isi gully in Daraga town and 1,200 along the Bonga gully in Legazpi City.

The collapse debris, meanwhile, has extended to approximate lengths of 3,300 meters from the volcano’s summit crater.

Meanwhile, in a separate volcanic activity report, Phivolcs said Mayon volcano’s state of unrest is "largely similar to Mayon’s 2014 eruption”.

The state seismologist added that the current restive activities in Mayon Volcano may persist for a few months and that Alert Level 4 and Alert Level 5 are likely to be hoisted.

But Phivolcs noted that the volcano’s condition may change any time, depending on slow and sustained lava extrusion, lava fountaining and lava flow with occasional explosions and PDCs within the 6 kilometer permanent danger zone (PDZ), and explosive eruption with high-intensity lava fountaining, long lava flows and PDCs on all sectors that could exceed the 6km-PDZ.

It reiterated that the Albayanos should remain vigilant against possible hazards including rockfalls or landslides or avalanches, ballistic fragments, lava flows and lava fountaining, PCDs, moderate-sized explosions, and lahars during heavy and prolonged rainfall.
