Mayon Volcano

Mayon volcano, also known as Mount Mayon, is an active stratovolcano in the province of Albay, on the island of Luzon, in the Philippines. Rising to 2,462 m above the Albay Gulf, it is one of the most beautifully symmetrical volcano in the world. The current cone was formed through pyroclastic and lava flows from past eruptions. Mayon volcano is the most active volcano in the Philippines, having erupted over 49 times in the past 400 years.

The Mayon volcano historical eruptions date back to 1616, ranging from strombolian to basaltic plinian, with cyclical activity beginning with basaltic eruptions, followed by longer term andesitic lava flows. Eruptions occur predominately from the central conduit and have also produced lava flows that travel far down the flanks. Pyroclastic flows and mudflows have commonly swept down many of the approximately 40 ravines that radiate from the summit and have often devastated populated lowland areas.
