The volcano has a 4 by 4.8 km (2.5 by 3.0 mi) wide caldera, and a single crater lake, Wonchi lake, about 450 m (1,480 ft) below the rim of the volcano.Study of Wonchi's caldera is incomplete; initial findings show it could be as much as 900 m (3,000 ft) deep, and the lake itself could be as deep as 400 m (1,300 ft).
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 ...
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]
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.
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 .
Higashi-Iwate was a later (300,000 years ago) parasitic volcano, which now forms the summit of the mountain. The oval-shaped, 1.8 x 3 km caldera of Nishi-Iwate has a 0.5 km wide crater, partially filled by a crater lake called Lake Onawashiro. Several somma including Yakushidake, the largest, surround the more recent Higashi Iwate crater rim.
Segara Anak is a crater lake in the caldera that formed during the explosive volcanic eruption of Mount Samalas in 1257. The caldera is next to Mount Rinjani on Lombok Island in Indonesia . "Segara Anak" means "child of the sea" and refers to the blue lake's resemblance to the sea.
