MAYON VOLCANO
Mayon
Volcano
One of the most dangerous volcanoes in the Pacific Ring of of Fire (Nielsen, 2020).
Previous study using InSAR data, showing evidence of a left-lateral oblique slip movement of the fault North of Mayon (Hidayat et al., 2011).
Sinistral Strike-slip fault
The figure is from Lagmay (2005)
Erupted 66 times in the last 420 years.
The first recorded eruption was in 1616, and the last major eruption was on January 2018.
The oldest exposed sample of deposits that was taken by Meyer in 1985, has been dated about 5,000 years of age (Villarta, et.al.,1985).
The longest eruption happened June 23, 1897 that lasted for seven 7 days.
The most devastating eruption happened on February 1, 1814 burying a nearby town to a depth of 9 meters where 2,200 people died (Cain, 2009).
Mayon Volcano is built through a combination of;
These build up to make a steep-sided structure (stratovolcano).

Lavas from Mayon Volcano in southeastern Luzon, Philippines, are compositionally variable. Now we understand the frequent eruptive activity of Mayon and the hazards/ risks from the past eruptions.
For the past 100 years Mayon has produced similar mild-intensity to explosive eruptions, and remarkably homogenous high-crystallinity basaltic andesite lavas.
