world's tourist spot: PHILIPPINES
Mayon Volcano , is an active stratovolcano located in the province of
Albay, Bicol Region, on the island of Luzon, in the Philippines.
It is reknowed because a conical shape, It is the main landmark of Albay Province, Philippines. It is 10 kilometres (6 mi) from the Gulf of Albay in the cities and municipalities of Legazpi City, Daraga, Camalig, Guinobatan, Ligao City, Tabaco City, Malilipot, and Santo Domingo (clockwise from Legazpi). It rises 2462 m (8,077 ft) above the gulf.[5]
Mayon Volcano is the Philippines' most active volcano and considered to be the world's most perfectly formed volcano for its symmetrical cone. It is a basaltic-andesitic volcano. The upper slopes of the volcano are steep averaging 35-40 degrees and are capped by a small peak crater. Its sides are layers of lava and other volcanic substance.
In recorded history Mayon has undergone forty-nine eruptions. The first recorded major eruption was in 1616. Its 48th and latest major eruption was a quiet effusion of lava on July 14, 2006, which was motivated when a lahar caused by the rains of Typhoon Durian followed on November 30, 2006. An added peak eruption occurred on August 10, 2008. Starting in January 2011, the volcano is faintly erupting and may be building up to a larger dangerous flare-up.The most destructive eruption of Mayon occurred on February 1, 1814. Lava flowed but not as much compared to the 1766 eruption. Instead, the volcano was belching dark ash and eventually bombarding the town with tephra that buried the town of Cagsawa—only the bell tower of the town's church remained above the new surface. Trees were burned; rivers were definitely damaged. Proximate areas were also devastated by the eruption with ash accumulating to 9 m (30 ft) in depth. 2,200 Albay locals perished in what is considered to be the most lethal eruption in Mayon's history. The eruption is believed to have contributed to the accumulation of atmospheric ash, capped off by the catastrophic eruption of Mount Tambora in 1815 that led to the Year without a summer in 1816.
