Lake Turkana (/ t ɜːr ˈ k ɑː n ə,-ˈ k æ n-/) is a saline lake in the Kenyan Rift Valley, in northern Kenya, with its far northern end crossing into Ethiopia. [2] It is the world's largest permanent desert lake and the world's largest alkaline lake.
An E-W-trending chain of small explosion craters cuts the eastern side of the 3-km-wide island. Several small islands to the SE represent partially submerged crater rims, and other cones and lava plugs lie beneath the lake surface near the island. The youngest Central Islands tuffs and lavas may be as young as Holocene (Karson and Curtis, 1992).
Landsat image of Lake Toba, Indonesia, the largest volcanic crater lake in the world. A well-known crater lake, which bears the same name as the geological feature, is Crater Lake in Oregon. It is located in the caldera of Mount Mazama. It is the deepest lake in the United States with a depth of 594 m (1,949 ft).
The volcanic island of Anak Krakatau in Indonesia saw an eruption on 22 December 2018 which caused a deadly tsunami, with waves surging up to five meters in height. The tsunami killed at least 437 ...
La Garita Caldera erupts in the Wheeler Geologic Area, Central Colorado volcanic field, Colorado, USA, eruption several VEI 8 events (Possibly as high as a VEI 9), 5,000 cubic kilometers (1,200 cu mi) of Fish Canyon Tuff was blasted out in a single, major eruption about 27.8 million years ago.
A volcanic crater is an approximately circular depression in the ground caused by volcanic activity. [1] It is typically a bowl-shaped feature containing one or more vents. During volcanic eruptions , molten magma and volcanic gases rise from an underground magma chamber , through a conduit, until they reach the crater's vent, from where the ...
The 1991 eruption of Mount Pinatubo, the largest eruption since 1912, is dwarfed by the eruptions in this list. In a volcanic eruption, lava, volcanic bombs, ash, and various gases are expelled from a volcanic vent and fissure.
An eruption on April 11 ejected a cloud of volcanic gas and ash that reached a height of 20 km (12 mi) and spread over an area of 108,000 km 2 (42,000 sq mi). [10] Pyroclastic flows from the eruption traveled up to 19 km (12 mi) away from the volcano.
