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 .
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.
Many of the world's largest lakes are located in rift valleys. [2] Lake Baikal in Siberia, a World Heritage Site, [3] lies in an active rift valley. Baikal is both the deepest lake in the world and, with 20% of all of the liquid freshwater on earth, has the greatest volume. [4]
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 ...
Why did the Death Valley lake form? In the past six months, a deluge of storms bringing record amounts of rain led to the lake's formation at Badwater Basin, which runs along part of central ...
At its height during the Last glacial period some 22,000 years ago, water filled Lake Manly to form a body of water that may have been 585 feet (178 m) deep and 90 miles (140 km) long. [33] Much smaller lakes filled parts of Death Valley during interglacials; the largest of these was 30 feet (9.1 m) deep and lasted from 5000 to 2000 years ago. [34]
Lake-filled half-graben showing sedimentation dominantly from the 'hinge' margin. Four zones of sedimentation can be defined in a half-graben. The first is "escarpment margin" sedimentation, found along the major border faults bounding the half graben, where the deepest part of the basin meets the highest rift-shoulder mountains. [6]
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.
