The lake fills Taal Caldera, a large volcanic caldera formed by very large eruptions between 500,000 and 100,000 years ago . It is the country's third largest lake after Laguna de Bay and Lake Lanao . Volcano Island, the location of Taal Volcano's historical eruptions and responsible for the lake's sulfuric content, lies near the center of the lake . There is a crater lake on Volcano Island . Known as the Yellow Lake or the Main Crater Lake, it contains its own small island, Vulcan Point .
