Mount Mayon is called as the most perfectly formed volcano
due to its symmetry. It is the most active volcano among the 22 volcanoes in
Philippines which was erupted over 47 times within past 400 years. Mount Mayon
is situated in province of Albay in Bicol Region, on the large island of Luzon in
the Philippines which rises above the Albay gulf to a height of 2462 m. It is
recorded that since 1616 Mount Mayon exploded with pyroclastic flows, mud flow
sand lava flows. That perfect shape was formed through layers of lava and
pyroclastic flows. So it is called as a stratovolcano which means a volcano
built up of alternate layers of lava and ash. It consists of small crater and
its upper slopes are steep with an average of 35-40 degrees. The volcanic
crater is about 250 m in diameter. About 85 lava flows have been identified and
it includes mainly augite-hypersthene-andesite. In the fact that Mount Mayon is
also belongs to Pacific Ring Of Fire, movement of oceanic plates can trigger an
eruption anytime.

Mount Mayon Eruption |
The first eruption happened in 1616. Most lethal event happened in 1st of February 1814. 1,200 people were died; town of Cagsawa got buried beneath 30 feet of ash. It destroyed Cagsawa church which was 10 Km away from volcano. This eruption lasted only for one day but Mayon emitted large amount of material during short period of time. In 23rd June 1897 Mayon eruption took place which was lasted for 7 days. This was the longest eruption and it destroyed trees, rivers and streams. In December 2006, more than 1000 people were died due to rains from powerful typhoon Durian caused mudslides and flood at the foot of the volcano.
Mayon’s last eruption happened
in 18th September 2014 but it
recorded higher levels of volcanic activity
in January 2018.In 1st of April 2020 Mayon Volcano’s seismic
monitoring network recorded one volcanic earthquake during 24 hour observation
period.
It is reported that P185 million in crops have been destroyed
in Albay due to Mayon volcano’s eruption and it affected about 9,791 farmers
and around 7,131 hectares of land. But it still attract many tourists because
of its perfectly formed cone shape.
