MANILA, Philippines — Mayon Volcano’s sulfur emission and rockfall events have decreased over the last 24 hours, the Philippine Institute of Volcanology and Seismology (Phivolcs) reported Wednesday.
In its 5 a.m. bulletin, Phivolcs said that Mayon released 1,170 tons of sulfur dioxide on July 4, lower than the 1,558 tons logged the day before.
On the other hand, rockfall events were at 232, slightly lower than the 257 recorded on July 3.
Meanwhile, the agency recorded one volcanic earthquake and five dome-collapse pyroclastic density current events (PDCs).
Phivolcs said that Mayon remains under Alert Level 3. It continues to display “intensified unrest or magmatic unrest,” and its “very slow” effusion of lava flow has reached 2.8 kilometers (km) along Mi-isi Gully and 1.3 km along Bonga Gully, while the other lava flows on both gullies remained at 3.3 km and 4 km along Basud Gully.
According to the National Disaster Risk Reduction and Management Council, Mayon’s continuous volcanic activity has affected 41,532 individuals or 10,655 families from 26 barangays within the Bicol Region and displaced 20,181 residents currently in more than 30 evacuation centers.
