List of landslides

This list of landslides is a list of notable landslides and mudflows divided into sections by date and type. This list may be incomplete as there is no central catalogue for landslides, although it does exist for some for individual countries or areas. Volumes of landslides are recorded in the scientific literature using cubic kilometres for the largest and millions of cubic metres for most events.
