Eruptions are unlikely to produce waves that extend beyond Crater Lake, but powerful explosions could produce tall waves in the caldera. [89] An eruption as explosive as the one 7,700 years ago is unlikely given that it would require larger volumes of magma than are known to be available within the Mazama vicinity. [ 22 ]
Quilotoa (Spanish pronunciation:) is a water-filled crater lake and the most western volcano in the Ecuadorian Andes.The 3-kilometre (2 mi)-wide caldera was formed by the collapse of this dacite volcano following a catastrophic VEI-6 eruption about 800 years ago, which produced pyroclastic flows and lahars that reached the Pacific Ocean, and spread an airborne deposit of volcanic ash ...
Crater Lake Institute Director and limnologist Owen Hoffman states that "Crater Lake is the deepest, when compared on the basis of average depth among lakes whose basins are entirely above sea level. The average depths of Lakes Baikal and Tanganyika are deeper than Crater Lake; however, both have basins that extend below sea level." [19] [21]
Copahue (Spanish pronunciation:) is a stratovolcano in the Andes on the border of Bío Bío Region, Chile and Neuquén Province, Argentina.There are nine volcanic craters along a 2 km (1.2 mi) line, the easternmost of which is historically the most active, and contains a 300 m (1000 ft) wide crater lake with a pH ranging between 0.18 and 0.30.

Following the eruption, thousands of fumaroles vented steam from the ash, creating the Valley of Ten Thousand Smokes. In 1919, geologists noted a lake covering a large part of the caldera floor. By 1923 the lake was gone and numerous fumaroles, mud pots, and a large mud geyser had replaced it. The lake has since refilled to a depth of over 800 ...
When news and photos of the first eruption in Iceland reached me in 2021, I was astonished. ... The 'roots' of the volcano extend deep underground through the eruption’s crater, just as ...
Kilauea began erupting around 2:30 a.m. Monday morning local time at the base of the Halemaumau Crater within the summit caldera after elevated seismic activity was detected overnight.
The peak is topped by a 1-kilometre (0.6 mi) wide summit crater, which contained a shallow crater lake until 1959. As of 2006, the crater lake had re-formed. [3] The last verified eruptions from the volcano were about 1,800 years ago, while reports of possible eruptions in 1692 and 1843 are considered uncertain. [1]
