1.Mayon is the archetype of a symmetrical stratovolcano and one of the world most active ones. It has frequent eruptions producing pyroclastic flows, mud flows and ash falls that repeatedly triggered large-scale evacuations.
2.It has a main crater lake which is blue-green in color and is 1.9 kilometers in diameter. The volcano has 47 craters in total, according to the Philippine Institute of Volcanology and Seismology. The rest of the volcano is below sea level. Taal Volcano features a caldera that also has water in it.
3.Pinatubo was an inconspicuous volcano, unknown to most people in the surrounding areas. Its summit was 1,745 m (5,725 ft) above sea level, but only about 600 m above nearby plains, and about 200 m higher than surrounding peaks, which largely obscured it from view.
4.Kanlaon, part of the Negros Volcanic Belt, is a large stratovolcano dotted with numerous flank cones and craters, many of which contain lakes. The summit of Kanlaon contains a 2-km-wide, elongated caldera with two craters. One is inactive and contains a crater lake.
5.Physical features. Bulusan is classified by volcanologists as a stratovolcano (or a composite cone) and covers the northeast rim of Irosin caldera that was formed about 40,000 years ago. It has a peak elevation of 1,565 m (5,135 ft) above sea level with a base diameter of 15 km (9.3 mi).
CAUSEOFERUPTION
1.Mayon is located on the Ring of Fire, the chain of volcanoes that sits along the edge of the Pacific Ocean. There are several subduction zones of various ages colliding slowly together near the Philippines, so volcanic activity is frequent there.
2.Taal volcano, like the other volcanoes in the Philippines, Japan and Indonesia, are a consequence of plate tectonics. An oceanic plate is being pushed (subducted) below an island arc. Melting begins at a depth of about 70km, and the magma, which is the molten rock below the earth's crust, rises up to feed volcanoes.
3.When even more highly gas-charged magma reached Pinatubo's surface June 15, the volcano exploded. The ash cloud rose 28 miles (40 km) into the air. Volcanic ash and pumice blanketed the countryside.
4.Canlaon volcano (also spelled Kanlaon) on Negros Island is one of the most active volcanoes of the Philippines and the most active one of the Central Philippines. It forms the highest peak of Negros Island and is located west of Canlaon about 36 km southeast of Bacolod City and belongs to Canlaon National Park.
5.Bulusan, one of the most active volcanoes in the Philippines, is Luzon's southernmost volcano. It lies at the SE end of the Bicol volcanic arc occupying the peninsula of the same name that forms the elongated SE tip of Luzon island.
