Mayon logs short gas bursts
Entering Mayon’s six-kilometer radius permanent danger zone remained prohibited due to the danger lava flows, rockfalls, and other volcanic hazards.
Daily TribuneEntering Mayon’s six-kilometer radius permanent danger zone remained prohibited due to the danger lava flows, rockfalls, and other volcanic hazards.
The Mayon Volcano in Albay province logged two "short-lived gas bursts" accompanied by seismic and infrasound signals in the past 24 hours, said the Philippine Institute of Volcanology and Seismology.
Phivolcs, however, said the activities are not an indication to raise the current alert level status of the volcano.
In its bulletin on Saturday, Phivolcs said the Mayon Volcano network recorded 31 volcanic earthquakes including 23 tremor events with a duration of one to 52 minutes, one pyroclastic density current event, and 87 rockfall events.
"Rockfalls and PDCs generated by the collapse of the summit dome deposited debris still within four kilometers of the crater," it said.
The gas burst with a slow effusion of lava occurred at 6:36 p.m. on 20 October and 12:06 a.m. on 21 October, respectively.
Phivolcs said the lava flows maintained advances to approximately 3.4 kilometers in Bonga (southeastern), 2.8 km in Mi-isi (south), and 1.1 km in Basud (eastern) Gullies.
Phivolcs observed a short-term inflation of the Mayon's edifice. Alert Level 3 status was maintained over the Mayon volcano, indicating that it is currently in a relatively high level of unrest.
Entering Mayon's six-kilometer radius permanent danger zone remained prohibited due to the danger lava flows, rockfalls, and other volcanic hazards. Flying aircraft near the volcano is also not allowed.
"Increased vigilance against PDCs, lahars, and sediment-laden streamflows along channels draining the edifice is also advised," Phivolcs warned.
