Mayon Volcano (Philippines): activity update
Mayon Volcano's seismic monitoring network recorded 3 rockfall related events over the past 24-hours. Steam plume emissions drifted west and west-northwest. Faint crater glow from the summit could be observed at night. Sulfur dioxide (SO2) emissions was measured at an average of 176 tonnes/day on 17 April 2020. Inflation of the middle to upper portions of the volcanic edifice that began in the last quarter of 2019 continues.

"DOST-PHIVOLCS reiterates that Alert Level 2 currently prevails over Mayon because the volcano is at a moderate level of unrest."
"It is therefore strongly recommended 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 should be strictly prohibited. The public is reminded that sudden explosions, lava collapse, pyroclastic density currents or PDCs and ashfall can occur without warning and threaten areas in the upper to middle slopes of Mayon. People residing close to these danger areas are also advised to observe precautions against 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 aircraft."

Mayon volcano (Luzon, Philippines) - Smithsonian / USGS Weekly Volcanic Activity Report for 8 April-14 April 2020 (Continuing Activity)
PHIVOLCS reported that during 7-14 April white steam plumes periodically emitted from Mayon rose as high as 400 m above the summit and drifted mainly NW, W, and SW. Crater incandescence was visible nightly. The Alert Level remained at 2 (on a 0-5 scale) and PHIVOLCS reminded residents to stay away from the 6-km-radius Permanent Danger Zone and the 7-km Extended Danger Zone on the SSW and ENE flanks. ...
