Mount Mayon is located on Luzon, the Philippines, and towers 2,463 metres into the sky. It is a stratovolcano, which are conical and are composed of hardened lava, tephra (ejected volcanic rock) and volcanic ash. Due to the high level of viscosity of the lava, it doesn’t travel from the site of the eruption. Over time, the accumulation of lava builds the steep-sloped sides of the volcano.
