The water impounded by a landslide dam may create a dam reservoir (lake) that may last from short times to several thousand years.
Landslide lakes are lakes created by the blockage of a valley by either mudflows, rockslides, or screes.

Dam

A landslide dam or barrier lake is a natural damming of a river by some kind of landslides, such as debris flows and rock avalanchess, or by volcanic eruptions.
Natural disasters such as earthquakes and landslides frequently create landslide dams in mountainous regions with unstable local geology.

Usoi Dam

Usoy
The highest known landslide dam of historic times is the Usoi Dam in modern Tajikistan created by a landslide triggered by an earthquake on February 18, 1911. It dammed the Murghab River to the height of 1860 ft to impound Sarez Lake 1657 ft deep.
The Usoi Dam is a natural landslide dam along the Murghab River in Tajikistan.

The highest known landslide dam of historic times is the Usoi Dam in modern Tajikistan created by a landslide triggered by an earthquake on February 18, 1911. It dammed the Murghab River to the height of 1860 ft to impound Sarez Lake 1657 ft deep. If the damming landslides are caused by an earthquake, it may also be called a quake lake. Some landslide dams are as high as the largest existing artificial dam. The major causes for landslide dams investigated by 1986 are landslides from excessive precipitation and earthquakes, which account for 84%.
The terrain below the Sarez Lake in Tajikistan is in danger of catastrophic flood if the landslide dam formed by the earthquake, known as the Usoi Dam, were to fail during a future earthquake.

2008 Sichuan earthquake

Sichuan earthquake2008 Wenchuan earthquakeWenchuan earthquake
The Tangjiashan Lake, a dangerous "quake lake", was created as a result of the 2008 Sichuan earthquake. It was located in the extremely rugged terrain of Tangjiashan Mountain. Chinese engineers, scientists, and soldiers were involved in the digging of a sluice to alleviate the dangers of this one of 34 landslide dams created by the magnitude 8.0 Sichuan earthquake. On June 10, 2008, the lake started to drain via the sluice, flooding the evacuated town of Beichuan. ( high)
The earthquake also caused the largest number of geohazards ever recorded, including about 200,000 landslides and more than 800 quake lakes distributed over an area of.

Tangjiashan Lake (, literally "Tang's Mountain landslide dam-created lake") is a landslide dam-created lake on the Jian River, which was formed by the 2008 Sichuan earthquake.

The Riñihuazo begun on 22 May 1960, after a landslide caused by the Great Chilean earthquake blocked Riñihue Lake's outflow. According to the chronicler Mariño de Lobera a similar event occurred after the 1575 Valdivia earthquake. ( high)
The Riñihuazo is the name given to the landslide damming of Riñihue Lake on 22 May 1960, after a landslide caused by the Great Chilean earthquake blocked its outflow.

Quake Lake

Earthquake Lake
Quake Lake, created in Montana in 1959. ( high)
The earthquake measured 7.5 on the Richter magnitude scale (revised by USGS to 7.3) and caused an 80-million ton landslide, which formed a landslide dam on the Madison River.

Lake Waikaremoana

Waikaremoana
Lake Waikaremoana in New Zealand was formed by a high landslide dam believed to be 2,200 years old. Between 1935 and 1950 the landslide was tunneled and sealed to stabilise it so it could be used for hydroelectric power generation. This appears to be the first example of modification of a natural landslide dam for power generation.
A huge landslide dam about 250 metres high formed the lake around 2,200 years ago.

Sarez Lake

Sarez
The highest known landslide dam of historic times is the Usoi Dam in modern Tajikistan created by a landslide triggered by an earthquake on February 18, 1911. It dammed the Murghab River to the height of 1860 ft to impound Sarez Lake 1657 ft deep.
Scientists believe that the landslide dam formed by the earthquake, known as the Usoi Dam, is unstable given local seismicity, and that the terrain below the lake is in danger of catastrophic flood if the dam were to fail during a future earthquake.

Tal-y-llyn Lake

The largest landslide dam in Britain impounds Tal-y-llyn Lake (Llyn Mwyngil) beside Cadair Idris in Snowdonia National Park, Wales. It was first recognised by E Watson in 1962. It is probably over 10,000 years old.
It is formed by a post-glacial massive landslip damming up the lake within the glaciated valley.

The 2014 Oso mudslide dammed the Stillaguamish River in March 2014, creating a lake that blocked Washington State Route 530 and hampered rescue/recovery efforts
Because of concerns that the mud and debris dam could fail and cause downstream flooding, the National Weather Service (NWS) issued a flash flood watch.

As a result of the magnitude 8.0 earthquake in Sichuan province of China on 12 May 2008, many rivers became blocked by landslides, resulting in the formation of so-called quake lakes: large amounts of water pooling up behind the landslide-formed dams.

Gros Ventre landslide

The "Gros Ventre landslide" is an example of a huge, short-lived and disastrous landslide dam ( high).
On May 18, 1927, a portion of the landslide dam failed, resulting in a massive flood that was 6 ft deep for at least 25 mi downstream.
