Authorities fear that more people will be killed by a flash flood caused by a glacial collapse in the Himalayan border areas of Nepal and adjacent Tibet. At least 270 people have been killed, but authorities are concerned about further casualties.

These are the most deadly glacial disasters of?history.

1941 -- HUARAZ (PERU)

In the northern Andes, a glacial 'lake outburst' flood inundated one-third of Huaraz. It killed an estimated 5,000. This remains one of the most deadly glacier-lake outbursts in history.

1962 -- RANRAHIRCA (PERU)

Mount Huascaran in Peru is the tallest mountain. A massive block of ice separated from it, and 10 million cubic meters of snow, rock and ice slid down the mountain within seven minutes. The ice block buried Ranrahirca, and other nearby settlements, under 12 meters of mud and debris. It killed an estimated 4,000.

1970 -- YUNGAY (PERU)

A magnitude 7.9 quake destabilized Mount Huascaran's northern wall, triggering the worst glacier disaster in recorded history. A mass of glacial ice, rock and debris hurled towards the towns of Yungay (208 mph) and Ranrahirca. They were buried in sludge.

The avalanche is estimated to have killed 25,000 people. This adds to the overall death toll of the?earthquake, which exceeds 50,000.

1981 -- CIRENMA CO., TIBET

A glacial mass that was overhanging plunged into Cirenma Co - a lake glacial 14 km away from the China/Nepal border - sending a massive wave over its moraine. Nearly 20 million cubic meters of water, debris and ice were hurled down to Nepal by the impact.

According to estimates, 200 people were killed in Nepal. Damage to roads, bridges, hydropower plants, and other infrastructure was estimated at $4 million.

CHAMOLI INDIA, 2021

A large chunk of ice fell from Ronti peak near Nanda Devi in India, the second highest mountain. It sent a torrent of dust, ice and rocks 1,500 metres into the valley.

The flash floods in Uttarakhand, a state in northern India, killed over 200 people and destroyed villages. Two hydroelectric projects were also swept away.

2026 -- NEPAL-TIBET BORDER

More than 1,000 people have gone missing in Nepal and Tibet. The lower section of the Himalayan glacier that crashed into the valley sent an avalanche down the Lhende Khola river along the mountainous border.

The mudslide that slammed Gyirong Port in Tibet, and then on to Nepal, created high-speed floods which washed out entire roads and power plants and inundated villages.

The police expect the death toll will rise above 270. (Reporting and editing by Hugh Lawson; Mei Mei Chu)
