Catalog record
These fields are copied from the Smithsonian Global Volcanism Program Holocene volcano snapshot stored on this site. The file was fetched 2026-09-19T12:21:44Z. It is a location catalog, not a live alert.

Elevation rank in the Eastern Philippine Volcanic Arc in this snapshot: 1 of 7. Rank is by the listed elevation only. It is not a hazard ranking.
How to read the last-eruption year
The year is a catalog field. A recent year means the snapshot recorded activity in that year. It is not an alert level, a size, or a statement about what happens next. Evidence codes in this file include “Eruption Observed” and “Eruption Dated.” Those are Smithsonian categories for how the eruption year was established, not a forecast flag.
Setting
Mayon is a stratovolcano at 2,462 m. The subregion field is Eastern Philippine Volcanic Arc, not the Luzon Volcanic Arc used for Taal and Pinatubo. The tectonic code is still subduction under continental crust. Splitting those subregions is the catalog’s distinction. This site’s single Philippines rectangle contains both.
The last-eruption year is 2026 and the evidence code is “Eruption Observed.” That records a year of activity in the fetched file. It does not say the eruption’s VEI, and this page does not assign one. USGS examples of VEI 5 and VEI 6 on this site are Mount St. Helens 1980 and Pinatubo 1991.
Inside these documented rectangles: Philippines. The rectangles are documented on the About page. They are a lat/lon belt, not an official plate polygon.
Other volcanoes in this subregion
Highest listed elevations in the Eastern Philippine Volcanic Arc in this snapshot, excluding this volcano when it is already first:
- Isarog, 1,966 m, last-eruption year 3500 BCE.
- Bulusan, 1,535 m, last-eruption year 2025.
- Biliran, 1,301 m, last-eruption year 1939.
Distance to published great-earthquake epicenters
The distances below use this volcano’s catalog coordinates and epicenters from the USGS list of the 20 largest earthquakes since 1900. They are spherical distances to points, not distances to a fault trace, and not a hazard score.
- 1938 M8.5 Banda Sea (1938-02-01 19:04 UTC) — 2,216 km from the catalog point.
- 2007 M8.4 southern Sumatra (2007-09-12 11:10 UTC) — 3,153 km from the catalog point.
- 2005 M8.6 Nias, Indonesia (2005-03-28 16:10 UTC) — 3,176 km from the catalog point.
You can repeat the measurement for any coordinates on the distance to fault references tool.
What this page will not tell you
It will not tell you the next eruption time, the next earthquake on the neighboring trench, or an evacuation route. For U.S. volcano notices, use the USGS Volcano Hazards Program. For earthquakes, use the USGS event pages linked from Live Quakes. This site’s volcano map only draws the Holocene catalog.
