MANILA, Philippines—A lava flow on Mayon Volcano, which happened on Sunday, was seen to etch its side 300 meters to 400 meters downhill, the volcanology institute said Tuesday.

In its Mayon bulletin, the Philippine Institute of Volcanology and Seismology (Phivolcs) said the lava flow happened on Sunday but was investigated through an aerial survey on Monday.
Mayon recorded four volcanic earthquakes from 8 a.m. Monday0 to 8 a.m. Tuesday with three rockfall events.
Moderate emission of white steam plumes drifting southwest and west-northwest was also observed.
Also, Phivolcs observed a faint crater glow at the volcano’s peak Monday evening.
Sulfur dioxide flux was recorded at 272 metric tons per day on Monday.
Mayon Volcano remains on alert level 3.
