Taal Volcano – Phillipines

Prev Next

Taal Volcano is a complex volcano on the island of Luzon in the Philippines. It consists of an island in Lake Taal, which is situated within a caldera formed by an earlier, very powerful eruption. It is located about 50 km (31 Miles) from the capital, Manila. It is one of the active volcanoes in the Philippines, all part of the Pacific ring of fire.The volcano has erupted violently several times, causing loss of life in the populated areas surrounding the lake, the current death toll standing at around 5,000 to 6,000. It was thought to be named as “a volcano inside a volcano” because many believed that the lake that circles the volcano was once a crater or mouth of a volcano.One of the more devastating eruptions occurred in 1911, which claimed more than a thousand lives. The deposits of that eruption consisted of a yellowish, fairly decomposed tephra with a high sulfur content. The last eruption was in 1977 but it has shown signs of unrest since 1991, with strong seismic activity and ground fracturing events, as well as the formation of small mud pots and mud geysers on parts of the island. Recently, on 8th June’ 2010, the Philippine Institute of Volcanology and Seismology rose its alert level, which indicates the volcano is undergoing magmatic intrusion which could eventually lead to an eruption.
