Mayon (Philippines) - Report for 13 August-19 August 2026 - Continuing Eruptive Activity — volcanic activity reported was recorded by Global Incident Tracker on Thursday, 20 August 2026 at 08:08 UTC. The event is classified as a volcanic eruption incident with a severity rating of Moderate, and was detected through GVP.
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported that the eruption at Mayon continued at low levels during 12-17 August. Each day the seismic network recorded 4-11 volcanic earthquakes; one rockfall was recorded each day on 15 and 18 August. An ash emission was visible on 12 August. Sulfur dioxide emissions (SO?) averaged 1,857-3,2957 tonnes per day (t/d) over this reporting period, but increased on 17 August to 8,393 t/d, well above the average of 2,532 t/d recorded since 5 August. The abrupt rise followed recent inflation of the N and E flanks recorded by electronic tilt deformation stations. Emissions declined to an average of 6,878 t/d on 18 August. The Alert Level remained at 2 (on a 0-5 scale) and the public was reminded to stay away from the 6-km-radius Permanent Danger Zone (PDZ). PHIVOLCS recommended that civil aviation authorities advise pilots to avoi
Where this happened
The incident is located in Philippines (Asia), whose capital is Manila. Historically, Philippines is most affected by typhoons, earthquakes, volcanic eruptions and floods. You can follow every incident recorded in this country, updated live, on the Philippines incident tracker.
Approximate coordinates of the reported event are 12.900°, 121.800°. The marker on the map above shows this position; for news-derived reports the location reflects the place named in media coverage and may represent a district or city rather than an exact site.
Understanding volcanic eruption events
Eruptions producing ash, lava, pyroclastic flows and lahars. Volcanic risk extends far beyond lava. Pyroclastic flows, ashfall that collapses roofs, lahars (volcanic mudflows) and aviation-grade ash clouds account for most volcanic casualties and economic damage.
How severity is rated
Global Incident Tracker rates every event on a four-step scale — Minor, Moderate, Severe and Extreme — derived from the source signal: earthquake magnitude, official GDACS alert colour, or the volume of independent media reporting for news-derived incidents. This event is currently rated Moderate. Ratings can change as more information becomes available, and a rating is a monitoring signal rather than an official government assessment.
Safety guidance for volcanic eruption situations
- Follow exclusion zones exactly — pyroclastic flows travel faster than any vehicle on local roads.
- Protect against ashfall with an N95 mask and eye protection; ash damages lungs and engines.
- Avoid river valleys and low ground downstream, where lahars concentrate.
- Clear roof ash carefully; wet ash is extremely heavy and collapses structures.
- Follow only official instructions from local authorities and emergency services — this page is a monitoring record, not an emergency alert.
Data and verification
This record was generated automatically from GVP and de-duplicated against our archive. Early reports for any incident can be revised: locations get refined, magnitudes are recalculated and impact figures change as assessments arrive. We deliberately do not publish casualty numbers unless an official source states them. The original source report is linked at the top of this page.
