Area affected by landslides vs earthquake magnitude Wenchuan earthquake Chi-Chi earthquake After Keefer 1984 and others, updated with recent events

The three key advances from the Chi-Chi earthquake : 

The three key advances from the Chi-Chi earthquake The spatial distribution of landslides, and their relationship with seismic parameters The role of topographic amplification in landslide initiation Post-seismic sediment production

1: Landslide distribution : 

Map: Khazai and Sitar (2003); Stats: Liao and Lee (2000), Lin et al. (2000) 1: Landslide distribution 21,000 landslides 9,727 landslides > 625 m2
