Taal Volcano Main Crater Lake

The Taal Volcano Main Crater Lake (IPA: [taʔal]; or simply Main Crater Lake[3]), also formerly known as Yellow Lake,[4] is a lake inside the main crater of Taal Volcano. The formation of the lake is unknown but possibly filled with rainwater accumulated over the years. The Main Crater Lake had disappeared after the 2020 Taal Volcano eruption.[5][6]

This article is about the lake inside Volcano Island. For the lake surrounding Volcano Island, see Taal Lake.

History

Disappearance

Further information: 2020 Taal Volcano eruption

After the eruption of Taal Volcano on January 12, 2020, satellite images showed that the water in the Main Crater Lake has disappeared and dried up.[7][8] Although the main cause of its disappearance is unknown, it is suggested that the water must have dried up due to the fissures that formed after the eruption.[7] The lava beneath the volcano may also have contributed to the evaporation of the lake.[5]

Vulcan Point Island, or simply Vulcan Point, was a small rocky island inside Main Crater Lake. It was one of few island in a lake on an island in a lake on an island in the world,[9] besides an unnamed Canadian island located within Victoria Island.[10][11][12] It projected from the surface of Main Crater Lake, which was the remnant of the old crater floor that was surrounded by the lake.
