The volcano remains under Alert Level 3.
On Saturday, May 2, the Mayon Volcano in Albay had another major activity after emitting pyroclastic density current (PDC) following the collapse of its lava flow.
According to the Philippine Institute of Volcanology and Seismology (PHIVOLCS) bulletin on Sunday, May 3, the volcano had a “lava effusion with lava flow on Basud (3.8 km), Bonga (3.2 km) and Mi-isi (1.6 km) gullies, with episodic minor strombolian activity and short-lived lava fountaining.”
That has caused the successive pyroclastic density currents (PDC) along Mi-isi Gully within the six-kilometer permanent danger zone (PDZ), and ashfall on the southwestern slopes.
So far, there have been 32 volcanic earthquakes including 25 volcanic tremors (2-15 minutes long); 284 rockfall and 14 PDC signals, according to state volcanologists.
There was also banaag or crater glow, which can be fairly seen through the naked eye. The Sulfur Dioxide Flux, meanwhile, was at 1586 tonnes / day as of May 1, 2026.
Mayon has also had a moderate emission of plume, which drifts in the west-northwestward direction.
PHIVOLCS also noted that there is a “short-term deflation of the edifice with shorter-term inflation on the northeastern flank.”
It reminded the public that entry into 6-kilometer radius Permanent Danger Zone (PDZ) and flying any aircraft close to the volcano are not permissible.
The bureau also warned of possible rockfalls or landslides or avalanches; ballistic fragments; lava flows and lava fountaining; pyroclastic density currents; moderate-sized explosions; and lahars during heavy and prolonged rainfall.
At present, Mayon Volcano remains under Alert Level 3 (Magmatic Unrest).
ALBAY PROVINCIAL GOV’T ADVISORY
In accordance with PHIVOLCS’ bulletin on Mayon Volcano Bulletin, the Albay provincial government, led by Governor Noel Ebriega Rosal, has advised all affected residents to remain indoors, wear N95 face masks if outdoor activity is absolutely necessary, and exercise extreme caution on ash-covered, slippery roads.
As such, the Albay Provincial Health Office has also started distributing face masks to local government units affected by ashfall while urging residents to take precautions against inhaling volcanic ash, as well as extended assistance to areas reporting ashfall incidents.
These include the municipalities of Camalig and Guinobatan, as well as Ligao City and the Josefina Belmonte Duran Albay Provincial Hospital.
A total of 400 N95 masks and 2,000 surgical masks were distributed to both Camalig and Guinobatan, while Ligao City received 2,000 surgical masks and the provincial hospital provided with 100 N95 masks and 2,000 surgical masks.
The office said it will continue rapid health assessments among internally displaced persons staying in evacuation centers to ensure their safety amid ongoing volcanic activity.
DSWD
For its part, the Department of Social Welfare and Development said it is on standby should the Albay provincial government requests for augmentation in terms of food and supply of basic items.
As of 6:00 am, the department said it has pre-positioned 301,311 Family Food Packs (FFPs), 27,322 Ready-to-Eat Food (RTEF) boxes, and 15,156 Non-Food Items (NFIs).
The DSWD Field Office (FO) 5 – Bicol Region has also released PHP 11,304,150.00 emergency cash transfer (ECT) and PHP 28,305,450.00 cash-for-work (CFW) fund—with the latter benefitting 2,169 farmers affected by the activities of the Mayon Volcano.
DOT
In its own statement, the Department of Tourism (DOT) advised the public that given the recent activities at Mayon Volcano, non-essential travel to areas surrounding is “strongly discouraged.”
“Travelers are urged to remain vigilant, plan ahead, and strictly comply with all local regulations and safety protocols,” it added.
Visitors are likewise advised to confirm bookings and schedules prior to travel and to rely only on official advisories issued by the Philippine Institute of Volcanology and Seismology (PHIVOLCS), concerned Local Government Units (LGUs), and the DOT.
“The Department underscores that the safety and well-being of tourists and tourism workers remain paramount, and will continue to monitor the situation closely in coordination with concerned agencies,” it concluded its statement.
