Detailed explanation-1: -Geology. Mayon is a classic stratovolcano with a small central summit crater. It is one of the world’s most symmetric volcanic cones. The concave profile, a hyperbolic sine curve of the volcano is due to the balance between erosion and eruption, defined by the angle of repose of ash.

Detailed explanation-2: -Mayon Volcano, active volcano, southeastern Luzon, Philippines, dominating the city of Legaspi. Called the world’s most perfect volcanic cone because of the symmetry of its shape, it has a base 80 miles (130 km) in circumference and rises to 8, 077 feet (2, 462 metres) from the shores of Albay Gulf.

Detailed explanation-3: -Mayon is a basaltic andesitic, open-vent volcano characterized by persistent passive degassing from the summit at 2463 m above sea level. Mid-size (< 0.1 km3) and mildly explosive eruptions and occasional phreatic eruptions have occurred approximately every 10 years for over a hundred years.

Detailed explanation-4: -Mayon, located in the Philippines, is a highly active stratovolcano with recorded historical eruptions dating back to 1616. The most recent eruptive episode began in early January 2018 that consisted of phreatic explosions, steam-and-ash plumes, lava fountaining, and pyroclastic flows (BGVN 43:04).

Detailed explanation-5: -Mayon Volcano stands 2462-meter-high and is located in province of Albay in the Bicol region at the southeast end of Luzon island.
