ABSTRACT
ABSTRACT: The August 3, 2014 Mw 6.1, Ludian, Yunnan, China earthquake triggered a large number of landslides. Some of the landslides buried quite a few settlements, which resulted in significant casualties and property losses. In this study, we compiled an inventory of the landslides triggered by the Ludian earthquake based on visual interpretation of preand post-earthquake high-resolution satellite images, and a selection was verified by very high-resolution aerial photographs and field photos. The result shows the Ludian earthquake triggered at least 1,024 landslides with area equal to or larger than 100 m2. These landslides are distributed in a 250 km2 area, with a total area of 5.19 km2 and a total estimated volume of 2.2 × 107 m3. The coseismic landslides were correlated with several topographic factors, e.g. elevation, slope angle, slope aspect, and topographic position.
