Earlier today, VAAC Tokyo sent an alert about a possible eruption and associated ash plume to 10,000 ft from the volcano, based on satellite imagery.
However, webcam images only show a moderate steam plume from the volcano and there is no mention of an eruption in the latest report of the volcano observatory. For this reason, it is likely that no explosion took place actually and that a weather cloud was mistaken for an ash plume. The overall activity of the volcano remains low to moderate; weak glow can be seen at night from the crater and seismic data reveal occasional rock falls (probably originating from the previously emplaced 2018 lava flows at the summit).
Sulfur dioxide (SO2) emissions are elevated, last measured at an average of 1,294 tonnes/day on 27 February 2019. The observatory recorded slight deflation during the past weeks, but reports that the longer trend of inflation of the mid-slopes since June 2018 is continuing. This means the volcano is gradually recharging towards its next eruption.
PHIVOLCS maintains "Alert Level 2" over Mayon Volcano:
"This means that Mayon is at a moderate level of unrest. DOST-PHIVOLCS reminds the public that sudden explosions, lava collapses, pyroclastic density currents or PDCs and ashfall can still occur and threaten areas in the upper to middle slopes of Mayon.
"DOST-PHIVOLCS recommends that entry into the six kilometer-radius Permanent Danger Zone or PDZ and a precautionary seven kilometer-radius Extended Danger Zone or EDZ in the south-southwest to east-northeast sector, stretching from Anoling, Camalig to Sta. Misericordia, Sto. Domingo must be strictly prohibited. People residing close to these danger areas are also advised to observe precautions associated with rockfalls, PDCs and ashfall.
"Active stream/river channels and those identified as perennially lahar-prone areas on all sectors of the volcano should also be avoided especially during extreme weather conditions when there is heavy and prolonged rainfall. Civil aviation authorities must advise pilots to avoid flying close to the volcano's summit as airborne ash and ballistic fragments from sudden explosions and PDCs may pose hazards to aircrafts."

PHIVOLCS reported that during 6-11 March white steam plumes periodically emitted from Mayon drifted WNW, WSW, and SW, and crater incandescence was visible each night. As many as six volcanic earthquakes and two rockfalls per day were recorded by the seismic network. Phreatic events recorded at 0811 on 7 March and 0627 on 8 March generated grayish ash plumes that rose 500 and 300 m above the crater, respectively, and drifted SW. ... Read all
