Mayon Volcano

Mayon Volcano, also known as Mount Mayon, is an active volcano in the province of Albay, on the island of Luzon in thePhilippines. Renowned as the "perfect cone" because of its almost symmetric conical shape, Mayon forms the northern boundary of Legazpi City, the largest city in terms of population in the Bicol Region. The mountain was first declared as a national park and aprotected landscape on July 20, 1938 in the country. It was reclassified and renamed as Mayon Volcano Natural Park in the year 2000.

Mayon Volcano is the main landmark of Albay Province, Philippines, rising 2,462 metres (8,077 ft) from the shores of the Gulf of Albay about 10 kilometres (6.2 mi) away.^[5][6]The volcano is geographically shared by the eight cities and municipalities of Legazpi City, Daraga, Camalig, Guinobatan, Ligao City, Tabaco City, Malilipot, and Santo Domingo (clockwise from Legazpi), which divide the cone like slices of a pie when viewed from above.

Geomorphology

Mayon is a classic stratovolcano type of volcano capped by a small central summitcrater. The cone is considered to be the world's most perfectly-formed volcano for its symmetry,^[6] 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. Magmamay be forced through weaknesses in the continental crust caused by the collision of the tectonic plates. One such exit point is Mayon.
