RIPIMO SHAR

 

Event description

 

Following three very warm days in July 1991, an ice avalanche fell into Chubung lake (Rowaling valley) causing it to burst through its terminal moraine dam at the southwestern end of Ripimo Shar Glacier and released about 0,5 - 1 Mio m³ of water. The water and finer material travelled downstream past the village of Na, where the flood killed some livestock and destroyed one bridge, and continued through the village of Beding. The flood wave killed one person, destroyed three flour mills and several potato fields.

Remarks

 

Following the July 1991 GLOF from Ripimo Shar, the villagers of Beding and Na within the Rolwaling Valley sought outside help as they perceived a serious risk of a future GLOF from Tsho Rolpa, a lake many times the size of Chubung.
