Taal caldera, seen here from its NW rim, is a 15 x 20 km caldera of Pleistocene and Holocene age. Volcano Island, in the north-central part of Lake Taal, is constructed of coalescing small tuff and scoria cones. Powerful phreatomagmatic explosive eruptions from several locations on the 5-km-wide island have produced deadly pyroclastic surges.
