Subansiri Dam
When the Subansiri Dam broke in August 1950, the dam of a naturally dammed lake in Tibet broke and caused a disaster.
background
A few days after the Assam earthquake of 1950 there was a dam break on the Subansiri , a tributary of the Brahmaputra . The dam was created by a landslide and was therefore not a man-made dam , but a natural dam. He dammed the water of the Subansiri until the dam was overflowed and broke eight days after the earthquake, i.e. on August 23, 1950. According to other sources, the dam broke after three days, on August 18, 1950. A 7 m high tidal wave was created , which resulted in 532 deaths in several villages.
consequences
The earthquake on August 15, 1950 in Assam and Tibet , with a magnitude of 8.6, was one of the strongest ever. The earthquake alone resulted in 1526 deaths. It was so strong that there were significant changes in the surface of the earth: in Upper Assam, in the Mishmi Hills, in the Arbor Hills; total in an area of 15,000 square miles (38,000 km²). Magnitude 8 (VIII) was exceeded in an area of 75,000 square miles (192,000 km²). The earthquake also caused landslides on the Dibang and the Dihing , further tributaries of the Brahmaputra, which formed dams, but which were washed away without causing damage.
