The disaster sent a massive surge of water, mud and rocks through the border region, destroying roads, bridges, vehicles and settlements. Initial reports suggested an earthquake may have triggered the disaster, but the US Geological Survey later said the seismic signal was generated by a glacial collapse and debris flow.The pilgrimage route, which had been planned around altitude acclimatisation, border formalities and rest days, was suddenly transformed into a disaster zone. Hundreds of people, including Indian nationals and other foreign tourists travelling towards Kailash Mansarovar, were reported missing after the floods.

Rising more than 6,400 metres (21,000 feet), it lies close to Lake Manasarovar, both deeply rooted in Sanskrit religious traditions.The mountain is sacred to Hindus, Buddhists, Jains and followers of the Tibetan Bon tradition. Hindus regard it as the abode of Shiva and Parvati, while Bon followers consider it a centre of spiritual power linked to founder Tonpa Shenrab. Geographer Emily Yeh wrote that Kailash is also associated with Mount Meru, the mythical centre of the world in Hindu and Buddhist cosmology.(With inputs from Prawesh Lama)
