About Taal Volcano and Lake
Taal Volcano and Lake are wholly located in the province of Batangas on the island of Luzon in the Philippines. The northern half of Volcano Island falls under the jurisdiction of the lake shore town of Talisay and the southern half to San Nicolas. The other towns that encircle Taal Lake include Tanauan, Talisay, Laurel, Agoncillo, Santa Teresita, Alitagtag, Cuenca, Lipa, Balete and Mataas na Kahoy. It is located about 50 kilometers (31 miles) south of the capital of the country, the city of Manila.
Taal Volcano is part of a chain of volcanoes along the western edge of the island of Luzon, which were formed by the subduction of the Eurasian Plate underneath the Philippine Mobile Belt. Taal Lake lies within a 25–30 kilometer caldera formed by 4 explosive eruptions between 500,000 and 100,000 years ago. Since the formation of the caldera, subsequent eruptions have created another volcanic island, within the caldera, known as Volcano Island. This island covers an area of about 23 sq kilometers (8.9 sq miles) and consists of overlapping cones and craters, 47 of which have been identified. Volcano Island contains a lake about 2 kilometers across, called Main Crater Lake, within which is another island, Vulcan Point.
There have been 33 recorded eruptions at Taal since 1572. Although the volcano has been quiet since 1977, 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.
