Mayon, also known as Mount Mayon and Mayon Volcano, is an active stratovolcano in the province of Albay in Bicol, Philippines. A popular tourist spot, it is renowned for its "perfect cone" because of its symmetric conical shape, and is regarded as sacred in Philippine mythology.

A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and solidifies before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high to intermediate levels of silica, with lesser amounts of less viscous mafic magma. Extensive felsic lava flows are uncommon, but have traveled as far as 15 km (9 mi).
