Webcam view of Mayon's lava flows last night (mostly cloudy views prevented cleaner images)The volcanic activity has continued with little changes, but shown a decreasing tendency. A recent gas measurement suggests a strong decrease in SO2 output from the volcano, which could suggest a beginning exhaustion of the magma supply.
On the other hand, GPS and tiltmeters continue to see inflation (swelling) of the volcanic edifice caused by internal magma pressure.
According to the latest bulletin from PHILVOLCS, "sporadic and weak lava fountaining" occurred in several episodes lasting between 3 and 55 minutes.
The view of the summit has been mostly obscured by clouds, but occasional partial views confirm that the lava flows and incandescent rockfall activity continues, mainly in the Miisi and Bonga-Buyuan channels.
The lava flow lengths remain at 3.3 km, 4.5 km and 900 meters distance at the Miisi, Bonga and Basud Gullies, respectively.
Philvolcs reminds that "Alert Level 4 remains in effect over Mayon Volcano. The public is strongly advised to be vigilant and desist from entering the eight (8) kilometer-radius danger zone, and to be additionally vigilant against pyroclastic density currents, lahars and sediment-laden stream flows along channels draining the edifice. Civil aviation authorities must also advise pilots to avoid flying close to the volcano’s summit as ash from any sudden eruption can be hazardous to aircraft."
