Elevation: 2,462 meters (8,077 feet)
Base Diameter: 20 km
Base Circumference: 62.8 km (reckoned from 10-km radius) encompassing the towns of Camalig, Malilipot and Sto. Domingo

Volcanic Activity

Number of Historical Eruptions: 48
Latest Eruption/Activity:

09 July 2009; 8:00 AM

Mayon Volcano’s status remains at Alert Level 1. This means that a hazardous eruption is unlikely. The public, however, is reminded that the 7-km Extended Danger Zone (EDZ) at the southeaster flank of the volcano and the 6-km radius Permanent Danger Zone (PDZ) at other areas remain off-limits due to the continuing threat from sudden small explosions and rockfalls from the upper slopes. Active river channels and those areas perennially identified as lahar-prone around the volcano should be avoided when there is heavy and prolonged rainfall.

Eruption Type:

Strombolian (e.g.. 1978, 1st phase of 1984 eruption)
Vulcanian (e.g. 1st phase of 1968 eruption, 2nd phase of 1984 eruption)
Plinian (e.g. 1814)

Precursors to Eruptions:

  1. Increase in seismicity level  (Background: 0-10 volcanic quakes per day)
  2. Ground tilt due to magma intrusion.
  3. Change in color of steam emission from white to gray due  to entrained ash
  4. Increase in the volume of steam emission
  5. Crater glow due to  presence of magma at or near the  crater.
  6. Rumbling sounds due to gas explosions, wall fracturing, landslides

Type of Hazards:

  1. Airfall tephra
  2. Lava flows
  3. Pyroclastic flows
  4. Lahars

    Just left the region and this is truly a natural wonder. Breathtaking. Awesome. Drawing your eyes to it as you approach. Power beyond belief ….. huge boulders 10’s of Kms from it. So capable of raining destruction and death yet people are living off the riches it provides such as fertile soil for rice, virtually on it’s slopes. To my eyes, oblivious to the risks.
    What is it. A curse or blessing to those it affects?
