Mayon Volcano’s effusive eruption continued for a 55th consecutive day on Sunday, March 1, with ongoing lava effusions, collapse from its summit crater, and minor strombolian activity, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS).
Ongoing Volcanic Activity
Time-lapse footage shared by PHIVOLCS showed lava effusion and collapse recorded at 1:58 a.m. And 6:56 p.m. On Sunday. Minor strombolian activity was also captured at 7:19 p.m. Sunday.
The eruption has generated incandescent lava flows, pyroclastic density currents (PDC) – locally known as “uson” – and rockfalls. Between 12 a.m. On February 28 and 12 a.m. On March 1, PHIVOLCS recorded 22 volcanic earthquakes, 310 rockfall events, and seven PDC signals.
Alert Level and Safety Measures
PHIVOLCS maintains Alert Level 3 for Mayon Volcano, meaning an eruption is possible. Entry into the six-kilometer Permanent Danger Zone (PDZ) remains strictly prohibited. The crater glow is visible to the naked eye, and plumes have risen up to 200 meters above the crater with moderate emissions.
Authorities continue to advise vigilance and adherence to evacuation guidelines.
Frequently Asked Questions
What is strombolian activity?
Strombolian activity is a low-level eruption characterized by intermittent bursts of gas and lava, as observed at 9:12 p.m. On Saturday and 7:19 p.m. On Sunday.
What are pyroclastic density currents?
Pyroclastic density currents (PDCs), or “uson”, are hazardous flows of hot gas and volcanic debris that move rapidly down the slopes of a volcano.
Is the volcano currently erupting ash?
PHIVOLCS reported minor ash emissions alongside the lava effusion and strombolian activity.
As Mayon Volcano continues its 55th day of eruption, what factors do you believe will be most critical in determining the future course of this event?
