Crater Lake is called Giiwas in the Klamath language. [7] Steel had helped map Crater Lake in 1886 with Clarence Dutton of the United States Geological Survey. The conservation movement in the United States was gaining traction, so Steel's efforts to preserve the Mazama area were achieved on two scales, first with the creation of the local ...
More than 30 eruptions have occurred since 1000 AD. [1] In 2007, an effusive explosion filled the crater with a lava dome. It last erupted on 13 February 2014, destroying the lava dome and ejecting boulders, stones and ashes up to West Java about 500 kilometres (310 mi) from Mount Kelud. The crater filled with water during the rainy season. [2] [3]
The area of the crater was increased by about 28%, and was enlarged laterally by about 300 m. [5] The crater rim was lowered about 60 m, moving nearer to the lake below. [5] The water level in the lake on Kasatochi significantly decreased following the eruption; however, several streams flowing out of the lower crater walls slowly refilled it.
Crater Lake actually started as a mountain, Mount Mazama. A volcanic eruption roughly 7,700 years ago caused the mountain to collapse inward over time, forming a volcanic crater, the park says.
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.

The crater was clearly changed by the eruption. A grey field of ash surrounds the crater and the caldera itself seems larger and deeper. The crater lake, which formed after Karthala's last eruption in 1991 and once dominated the caldera, is now gone completely. In its place were rough, dark grey rocks, possibly cooling lava or rubble from the ...
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 .
The summit of the volcano is a steep-walled heavily forested crater that opens to the south with a peak elevation of 860 metres (2,820 ft). Located on the volcano flanks are fumaroles and mudpots . On the southern flank of the volcano, two crater lakes are located, Lakes Danao and Malagsom .
