Abstract
AbstractSeismotectonics and change in river courses were correlated. Following the elastic rebound theory before the occurrence of the earthquake the subsurface rocks accumulate the energy by the tectonic movement. The Kosi river barrage was broken due to the tectonic forces accumulation in the south of Tibet Himalayas. Kosi river originates from Tibetan Himalayas and any disturbance in Tibet plateau has the potential to change the river course.
Highlights
A strong earthquake measuring 6.8 magnitude struck Tibet on Monday 25th August 2008
The China Earthquake Network Center (CENC) reported that a 6.8magnitude earthquake shook Zhongba County, Xigaze which is situated in the western region of Tibet
The river along with its tributaries, drains a total area of 69,300 sqkm up to its confluence with the Ganga in India (29,400sqkm in Tibet, 30,700 km[2] in Nepal and 9,200 sqkm in India), a part of Tibet (China) including the Mount Everest region as well as the eastern one third of Nepal.The river basin is surrounded by the ridges separating it from the Brahmaputrain the north, the Gandaki in the west, Mahananda in the east and by the Ganga in the south
Summary
The China Earthquake Network Center (CENC) reported that a 6.8magnitude earthquake shook Zhongba County, Xigaze which is situated in the western region of Tibet. The alignment of the faults in Tibet platue has connection with the Kosi river.Kosi River, is a transboundary river between Nepal and India and is one of the largest tributaries of the Ganga. Kosi river originates in Tibetan Himalayas at a height of 18,000 feet and drains a catchment of 22988 sq. It has been hypothetically established that before the occurrence of tectonic earthquake the strata gets uplifted in one part and goes down in other portion.
