Catastrophic slope processes in glaciated zones of mountainous regions -- Slope instability phenomenon in the permafrost region along the Qinghai-Tibetan Highway, China -- Occurrence mechanism and movement characteristics of landslides in Bei'an to Heihe expressway area in China under the climate change -- Forming mechanism of landslides in the seasonal frozen loess region in China -- Investigation and mechanism clarification of the 2011.1.5 Atom-en landslide in Kashima area, Matsue city -- Bedding landslide formation mechanism and traits in Lesser Khingan Mountain.The impact of freeze-thaw on the stability of soil cut slope in high-latitude frozen regions -- Effect of solar energy absorption in the embankment of the Qinghai-Tibet railway in the permafrost region. Landslides in cold regions have different mechanisms from those in other areas, and comparatively few research efforts have been made in this field. Recently, because of climate change, some new trends concerning landslide occurrence and motion have appeared, severely impacting economic development and communities. This book collects key case studies from the cold regions all over the world, providing an overview of the general situation.
