Mayon Volcano Legazpi City, Albay Mayon Volcano, also known as Mount Mayon, is an active volcano in the province of Albay, on the island of Luzon in the Philippines. 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 is a national park and a protected landscape in the country proclaimed as Mayon Volcano Natural Park in the year 2000. Local folklore refers to the volcano as Bulkang Magayon (Bikol: 'Beautiful Volcano'), after the legendary heroine Daragang Magayon (Bikol: 'Beautiful Lady'). 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. The volcano is geographically shared by the 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. 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 acontinental 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.
