Mayon is a classic stratovolcano (composite) type of volcano with a small central summit crater. The cone is considered the world's most perfectly formed volcano for its symmetry, which was formed through layers of pyroclastic surges and lava flows from past eruptions and erosion.ike other volcanoes located around the Pacific Ocean, Mayon is a part of the Pacific Ring of Fire. It is located on the eastern side of Luzon, near the Philippine Trench which is the convergent boundary where the Philippine Sea Plate is driven under the Philippine Mobile Belt.
Mayon's most violent eruption, in 1814, killed more than 1200 people and devastated several towns. (Description courtesy SI/USGS Global Volcanism Program). Mayon volcano, in SE Luzon, is the most active volcano in the Philippines.Its classic, symmetrical profile, which rises above the Albay Gulf to a height of 2462 m, is the result of a structurally simple volcano where eruptions have occurred from a single central conduit.he initial eruption lasted only 30 minutes but it generated pyroclastic flows that killed 68 people and prompted the evacuation of 60,000 others.
