Mayon still restless: Phivolcs logs 3 earthquakes, 286 rockfalls
MANILA, Philippines — Mayon’s restiveness persisted in the past 24 hours.
In the latest monitoring period, state volcanologists observed three volcanic earthquakes, 286 rockfall events, and 10 pyroclastic density current events at the volcano.
The Philippine Institute of Volcanology and Seismology (Phivolcs), in its bulletin issued on Thursday, said from 5 a.m. on July 12 to 5 a.m. on July 13, that the volcano’s effusion of lava also continued.
“The lava flows have advanced to approximate lengths of 2,800 meters and 1,400 meters along Mi-isi and Bonga gullies, respectively, from the summit crater while collapse debris has deposited to 4,000 meters from the crater along the Basud channel,” said Phivolcs.
Phivolcs added that Mayon’s sulfur dioxide emission likewise persisted, generating an average of 1,582 metric tons on July 12.
With these indicators, Phivolcs stressed that Mayon is still under Alert Level 3. The volcano, which was raised from Alert Level 2 to 3 on June 8, is seen to exhibit this type of unrest for months.
