Restive Mayon posts 79 volcanic quakes, 216 rockfall events in 24 hours
MANILA, Philippines — State volcanologists on Friday said Mayon Volcano’s restlessness continued, as it registered 79 volcanic earthquakes and 216 rockfall events in the last 24 hours.
In a bulletin, the Philippine Institute of Volcanology and Seismology (Phivolcs) also said that Mayon discharged lava and sulfur dioxide from 5 a.m., July 6, to 5 a.m. July 7.
Seven dome-collapse pyroclastic density currents were likewise recorded in the same period, Phivolcs said.
The latest number of rockfall events was a steep increase as state volcanologists recorded zero during the previous 24-hour monitoring cycle.
Additionally, Phivolcs said lava flows have now advanced to approximate lengths of 2,800 meters and 1,300 meters along the Mayon’s Mi-si and Bonga gullies, respectively, while sulfur dioxide emission was logged at 976 metric tons on July 6.
“Alert Level 3 is maintained over Mayon Volcano, which means that it is currently in a high level of unrest as magma is at the crater and hazardous eruption within weeks or even days is possible,” Phivolcs stressed in its bulletin.
“Increased vigilance against pyroclastic density currents, lahars, and sediment-laden streamflows along channels draining the edifice is also advised. Heavy rainfall could generate channel-confined lahars and sediment-laden streamflows in the channels where pyroclastic density currents were emplaced,” it added.
