>This volume documents further advances in our knowledge of catastrophic landslides since the pioneering compilations of the late 1970s by Barry Voight. It provides a worldwide survey of catastrophic landslide events written by leading authorities. Catastrophic Landslides begins by drawing upon South America to dramatically illustrate the impact of these phenomena on human populations. The occurrence of catastrophic landslides, including site-specific insights, is shown through six events of the past 20 years. Several other chapters focus on the mechanisms involved with catastrophic landsides both in relation to geologic factors in a particular geographic area as well as to specific geologic processes.

Abstract
In December 1991, 11.8 ± 2.4 × 106 m3 of rock and ice fell from Mount Cook (3754 m), the highest peak in New Zealand's Southern Alps. It fell 2720 m in 2 min and traveled 7.5 km (averaging 60 m/s). It generated a magnitude (ML) 3.9 earthquake, becoming finely comminuted and doubling in mass through erosion.
In December 1991, rockfalls began at Mount Fletcher (2467 m) 30 km northwest of Mount Cook. They continued until the ridge north of Mount Fletcher fell in rock avalanches in May and September 1992. They dropped 1440 m...
