A volcanogenic lake is a lake formed as a result of volcanic activity. [1] They are generally a body of water inside an inactive volcanic crater ( crater lakes ) but can also be large volumes of molten lava within an active volcanic crater ( lava lakes ) and waterbodies constrained by lava flows, pyroclastic flows or lahars in valley systems.

The crater lake of Mount Rinjani, Indonesia Lake Yeak Laom, Cambodia Baengnokdam crater lake of Hanla Mountain in winter, South Korea A volcanic crater lake is a lake in a crater that was formed by explosive activity or a collapse during a volcanic eruption .
Crater lake, a volcanic lake in Oregon. Volcanoes that, though large, are not large enough to be called supervolcanoes, may also form calderas (collapsed crater) in the same way. There may be active or dormant cones inside of the caldera or even a lake, such lakes are called Volcanogenic lakes, or simply, volcanic lakes. [37] [2]
The lake partly fills a 2,148-foot-deep (655 m) caldera [3] that was formed around 7,700 (± 150) years ago [4] by the collapse of the volcano Mount Mazama. No rivers flow into or out of the lake; the evaporation is compensated for by rain and snowfall at a rate such that the total amount of water is replaced every 150 years. [5]

A subglacial volcano, also known as a glaciovolcano, is a volcanic form produced by subglacial eruptions or eruptions beneath the surface of a glacier or ice sheet which is then melted into a lake by ...
The earliest known lava in this cycle is the Wapiti Lake flow of the Mount Jackson group, dated at 1.2187 ± 0.0158 million years, [69] exposed near the Grand Canyon of the Yellowstone and likely vented near Wapiti Lake. [70] Another flow, the Moose Creek Butte flow (1.1462 ± 0.0022 million years), also belongs to the Mount Jackson group. [71]
Nyiragongo's lava lake has usually been the largest and most voluminous in recent history, reaching 700 meters wide in 1982, [15] although Masaya is believed to have hosted an even larger lava lake at the time of the Spanish conquest, being 1,000 meters wide in 1670. [16] The lava lake at Masaya came back in January 2016. [17]
Crater Lake sits partly inside the volcano's caldera, [6] with a depth of 1,943 feet (592 m); [note 1] it is the deepest body of freshwater in the United States [7] [8] and the second deepest in North America after Great Slave Lake in Canada. [11]
