Taal Volcano

Where in the world is there a lake in an island within a lake, in an island on an ocean? Thats Taal Volcano, regardless as the smallest active volcano in the world. There have 33 eruptions since 1572, the impact of which were mostly confined on the volcano island. However fallout of the 1754 plinian eruptions effected the entire regions, including what is now Metro Manila. Its last eruption was in 1977, which caused only minor damage. Its last violent eruption was in 1965 when it killed 200 people.In light of its proximity to populated areas and violent eruptive history, Taal has been designated one of sixteen Decade Volcanoes, making it a focus for research efforts and disaster mitigation plans. While seismic activity is a common precursor to eruptive activity, another useful indicator at Taal is the temperature of Lake Taal. Before the 1965 eruption began, the lake's temperature rose to several degrees above normal. However, the lake's temperature does not always rise before an eruption. Before some eruptions, the dissolution of acidic volcanic gases into the lake has resulted in the death of large numbers of fish.
