Mayon Volcano

Mayon Volcano, also known as Mount Mayon, is an active volcano located in Legaspi City Albay, on the island of Luzon in the PHILIPPINES. Renowned as the "perfect cone" because of its almost symmetric conical shape. The cone is considered to be the world's most perfectly-formed volcano for its symmetry. It is the most active volcano in the Philippines having erupted over 48 times in the past 400 years.


Mayon Volcano

Mayon is a classic stratovolcano type of volcano capped by a small central summit crater. The cone is considered to be the world's most perfectly-formed volcano for its symmetry, which was formed through layers of pyroclastic and lava flows from past eruptions and erosion. The upper slopes of the basaltic-andesitic volcano are steep averaging 35–40 degrees.

Like other volcanoes located around the Pacific Ocean, Mayon is 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. When a continental plate or belt of continental fragments meets an oceanic plate, the lighter continental material overrides the oceanic plate, forcing it down into the Earth's mantle. Magma may be forced through weaknesses in the continental crust caused by the collision of the tectonic plates. One such exit point is Mayon.

Mayon Volcano

Mayon Volcano is the most active volcano in the Philippines, and its activity is regularly monitored by PHIVOLCS from their provincial headquarters on Lignon Hill, about 10 kilometres (6.2 mi) SSE from the summit.

Three telemetric units are installed on Mayon's slopes, which send information to the seven seismometers in different locations around the volcano. These instruments relay data to the Lignon Hill observatory and the PHIVOLCS central headquarters on the University of the Philippines Diliman campus. PHIVOLCS also deploys electronic distance meters (EDMs), precise leveling benchmarks, and portable fly spectrometers to monitor the volcano's daily activity.
