This view of Main Crater Lake, filling a small 3-km-wide caldera on Volcano Island, looks across distant Lake Taal to the NE rim of the 15 x 20 km Taal caldera. The surface of the 267 km2 lake is only 3 m above sea level. Volcano Island has been the source of all historical eruptions. Explosive eruptions have produced pyroclastic surges that swept across Lake Taal and devastated lakeshore areas. Pleistocene eruptions that formed the caldera greatly modified the topography of southern Luzon Island.
