Mayon Volcano

Mayon Volcano has a worldwide reputation as the most perfectly formed volcano in the world because of its near-perfect conical shape and form. Mayon Volcano is the champion among the best competitors for the world's most perfectly coned volcanoes like Osorno Volcano of Chile, Mount Fuji of Japan, Mount Taranaki of New Zealand, Mount Cotopaxi of Ecuador, Volcan Arenal of Costa Rica and Shishaldin Volcano of Alaska, USA. Because of its natural elegance and beauty, it is listed on the World's Top 10 Wonders of Nature. Visitors traveling to Mayon Volcano from Manila would take an hour by plane getting to Legazpi City then 10 miles north of Legazpi city is the magnificent Mayon Volcano, the most popular landmark of the province of Albay, Philippines.

Geomorphology
Mayon Volcano is an active stratovolcano. The current cone was formed through pyroclastic and lava flows from past eruptions. Mayon is the most active of the active volcanoes in the Philippines, having erupted over 49 times in the past 400 years.


Like other volcanoes located around the ring of the Pacific Ocean, Mayon is part of the Pacific Ring of Fire. It is located on the eastern side of Luzon, beside the Philippine Trench which is the convergent boundary where the Philippine Sea Plate is driven under the Philippine Mobile Belt. Where 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.

Location and formation

Mayon Volcano is the main landmark of Albay Province, Philippines. It is 10 kilometres (6 mi) from the Gulf of Albay, in the cities and municipalities of Legazpi City, Daraga, Camalig, Guinobatan, Ligao City, Tabaco City, Malilipot, and Santo Domingo (clockwise from Legazpi). It rises 2462 m (8,077 ft) above the gulf.

Mayon Volcano is the Philippines' most active volcano and is considered to be the world's most perfectly formed volcano for its symmetrical cone. It is a basaltic-andesitic volcano. The upper slopes of the volcano are steep averaging 35-40 degrees and are capped by a small summit crater. Its sides are layers of lava and other volcanic material.
