Crater Lake is the largest lake in the world on an island in a lake which itself is located on an island! The island of Vulcan Point is contained within Crater Lake, which in turn is located in the Taal Volcano. This second island is located in Lake Taal, which is located on the island of Luzon, the main island of the Philippine archipelago.
The entire volcano is a huge caldera, mostly hidden from the lake. The volcano is included in the Taal Volcano Protected Landscape Area, created in 1996 by the then president of the Philippines Fidel V. Ramos. The park extends around the caldera area and overlooks the lake on whose shores there are a fair number of hotels and tourist resorts.
Typical is the smell of sulfur perceptible throughout the area around the volcano and the vapors that, on the way down to the lake, welcome visitors. The protected area was proposed in 2006 by the Department of Environment and Natural Resources as a UNESCO World Heritage Site.
The Taal volcanic system consists of the large caldera formed following a strong eruption that occurred between 140,000 and 6,000 years ago with a diameter of 25 kilometers, the lake and the volcanic cone that rises in the middle like an island and all inside of which there is a smaller lake.
The originality of this system of a lake in the lake makes the Taal a unique volcano for scholars and tourists. The small lake located in the crater, blue and green in color and with a maximum depth of 76 meters, is located at an altitude of 4 m a.s.l.
and has a diameter of just under two kilometers. The cone of the crater, which forms an island, hosts 47 other small craters and 4 maars; the cone of the crater is in turn placed in the middle of Lake Taal which occupies an area of 267 square kilometers.
The whole is at the center of a huge 25-kilometer-wide caldera resulting from a huge eruption that occurred in a non-historical era and which would have demolished the original volcanic plant. Near the Taal, which is part of the Macolod tectonic corridor, are the Makiling (1 090 m), Malepunyo (865 m), Batulao (811 m) and Macolod (957 m) volcanoes.
The Taal has had 34 ascertained eruptions in historical times of which, among others, a plinian in 1754, two Strombolian in 1968 and 1969, three phreatomagmatic in 1749, 1965 and 1966 and three phreatic in the years 1878, 1911 and 1970.
