Abstract
Earthquake-triggered landslides (ETLs) are among the most significant of all natural hazards. Triggering mechanisms and the continued development of landslides are complex and variable in different environmental settings. Field investigation and/or visual interpretation are two popular ways of landslide mapping. Detailed landslide inventories containing almost all ETLs for a region and the geo-environmental factors provide the basic data to understand the complex factors controlling landslide development. There are more than 86 published inventories for ETLs for individual earthquakes. Significant relationships between the areas affected by ETLs and the maximum distance from the epicenters versus the earthquake magnitudes are evident. Other than the commonly used terrain, geology, and earthquake factors, the characteristics of the underlying stratum, seismogenic fault, and rupture process should consider the occurrence mechanism, spatial distribution, and susceptibility mapping of the regional ETL research. Landsliding activity continues for years to decades, and the erosion and sediment flux change for several decades after a major earthquake.
