Faulted southeastern side of Svyatoy Nos peninsula, Lake Baikal – active faulting shown by faceted spurs. Artificial rendering of the Albertine Rift showing four of its rift lakes A rift lake is a lake formed as a result of subsidence related to movement on faults within a rift zone, an area of extensional tectonics in the continental crust .
Lake Baikal is an unusually large and deep example of half-graben evolution. The lake is 630 by 80 kilometres (391 by 50 mi), with a maximum depth of 1,700 metres (5,600 ft). Sediment in the depression may be up to 6,000 metres (20,000 ft) in depth. The system also includes some small Quaternary volcanoes. [10]
Diagram showing how earthquakes can generate a tsunami. Tsunamis in lakes can be generated by fault displacement beneath or around lake systems. Faulting shifts the ground in a vertical motion through reverse, normal or oblique strike slip faulting processes, this displaces the water above causing a tsunami (Figure 1).
An anchialine system (/ ˈ æ ŋ k i ə l aɪ n /, from Greek ankhialos 'near the sea') is a landlocked body of water with a subterranean connection to the ocean.Depending on its formation, these systems can exist in one of two primary forms: pools or caves.
The Rift Valley lakes are a series of lakes in the East African Rift valley that runs through eastern Africa from Ethiopia in the north to Malawi in the south, and includes the African Great Lakes in the south. These include some of the world's oldest lakes, deepest lakes, largest lakes by area, and largest lakes by volume.
Tectonic lakes are lakes formed by the deformation and resulting lateral and vertical movements of the Earth's crust. These movements include faulting, tilting, folding, and warping. Some of the largest lakes on Earth are rift lakes occupying rift valleys, e.g. Central African Rift lakes and Lake Baikal.
These three beds preserve the early sedimentation of Lake Malawi. The water surface was probably 300 meters higher above sea level than it is presently, confined to an area a quarter of its present size in the north. Geologists believe that down-faulting allowed the lake water to flow to lower elevations, extending to Cape Maclear Peninsula ...
The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes spanning the Canada–United States border.The five lakes are Superior, Michigan, Huron, Erie, and Ontario (though hydrologically, Michigan and Huron are a single body of water, as they are joined by the Straits of Mackinac).
