Rockslides and rock avalanches in the Central Asian republics of the former Soviet Union are discussed in detail for the first time in an English-language book. These landslides include the 1911 Usoi rockslide, that dammed 75 km-long Lake Sarez, and the 1949 Khait rock avalanche that may have killed up to 28,000 people. Both landslides were earthquake-triggered and both are located in Tajikistan. An additional highlight is a detailed description and analysis of large-scale artificial rock avalanches triggered by underground nuclear explosions during the testing programme of the former Soviet Union.
