Abstract

After the March 28, 1999, Garhwal earthquake, 338 active landslides, including 56 earthquake-induced landslides, were mapped in the Garhwal Himalaya. These landslides many comprised shallow failures in regolith and highly weathered bedrock involving avalanches, slides, and flows. Two-thirds of the landslides in this region were initiated or accelerated by human activity, mostly by the removal of slopes toes at road cuts, suggesting that human activity is accelerating denudation in this region. Three ancient catastrophic landslides, each involving > 1 million m3 of debris, were identified and dated to the early-middle Holocene. Natural landsliding, therefore, contributes 5-50% of the overall denudation in this region
