Metro Manila (CNN Philippines, June 21) — Lava continues to flow slowly from Mayon Volcano’s summit crater, maintaining its maximum length in the last 24 hours, the Philippine Institute of Volcanology and Seismology (Phivolcs) said Wednesday.
According to Phivolcs’ latest observation report, the lengths of Mayon’s lava flow are still 2.5 km and 1.8 km long along Mi-isi and Bonga Gullies, respectively.
State volcanologists also said they recorded two volcanic earthquakes, 299 rockfall events, and seven dome-collapse pyroclastic density current events from 5 a.m. on Tuesday to 5 a.m. on Wednesday.
A small-volume pyroclastic density current (PDC) also occurred between 6:32 p.m. and 6:38 p.m. on Tuesday, which was generated by a collapse from the summit lava dome of the volcano, Phivolcs said in a separate social media post.
“PDCs were absent for much of the day, indicating a short-term easing of lava effusion from the summit crater,” it added.

On June 20, Phivolcs said Mayon emitted 507 tons of the harmful sulfur dioxide.
Alert Level 3 remains hoisted over Mayon.
Latest government data showed that over 20,000 residents in Albay were displaced due to Mayon’s eruption.
