Geomorphic impacts, age and significance of two giant landslide dams in the Nepal Himalayas: Ringmo‐Phoksundo (Dolpo District) and Dhampu‐Chhoya (Mustang District).
Résumé
Large catastrophic slope failures have recently retained much attention in the northern dry Himalayas (Hewiitt 2009). They play a prominent role in the denudation history of active orogens at a wide range of spa7al and 7me scales (Korup & Clague, 2009), and they impact durably landforms and process evolution in upstream catchments. Their occurrence mostly results from three different potential triggers: earthquakes, post‐glacial debuttressing, and permafrost melting. We focus on two examples
of giant rock slope failures that occurred across and north of the Higher Himalaya of Nepal and assess their respective influence on the regional, geomorphic evolution.
