Earthquake-triggered landslides and liquefaction: how bad will it be?

: Abstract Earthquake-triggered landslides are a very important phenomenon, particularly in high mountainous regions such as the Andes and the Himalayas which are prone to earthquakes. However, despite having caused the loss of many lives and the destruction of much infrastructure, they have not always received the attention they deserve from engineers planning the construction of large dams. Hydrological events following earthquakes also pose a great problem and a fully integrated approach is advised. Important risks related to earthquake-triggered landslides are the blockage of spillways and the generation of displacement waves in reservoirs. However, there is also a need to consider the risk of landslides a distance upstream of a dam. These can cause landslide dams that block rivers and, when they are eventually overtopped and washed away, lead to large releases of water. Monitoring of potentially unstable areas may be appropriate.
