MANILA, Philippines — Mayon Volcano was rocked by 57 earthquakes and 225 rockfalls, spewing ash four times over the past 24 hours.
The Philippine Institute of Volcanology and Seismology (Phivolcs) reported Wednesday that Mayon’s activities were much lower than the one minute and 17 seconds long 258 volcanic earthquakes and 57 ash events recorded on July 31.
The rockfalls also spiked from 100 on July 31 to 225 on August 1.
Mayon’s sulfur dioxide emission also climbed from 2,325 tons on July 31 to 2,709 tons on August 1.
Phivolcs also documented how far Mayon’s lava eruption and flow traveled.
The slow lava effusion from the volcano, which remains under Alert Level 3, extended 2.8 kilometers (km) along Mi-isi Gully, 3.4 km in Bonga Gully, and 600 meters in Basud Gully, while lava eruption reached 4 km from the crater.
Phivolcs warned residents that rockfalls, landslides, avalanches, ballistic fragments, lava flows, and moderate-sized explosions might occur near Mayon.
Mayon’s unrest has impacted 38,396 individuals or 9,876 families as of August 2, according to the National Disaster Risk Reduction and Management Council.
