Introduction

Paleoseismic landslide analysis involves three steps (1) Identifying a feature as a landslide. (2) Dating the landslide. (3) Showing that the landslide was triggered by earthquake. - Interpreting an earthquake origin for landslides. - Slope-stability analysis Interpreting results of paleoseismic landslide studies.

Identifying landslides Paleoseismic landslide analysis involves three steps (1) Identifying a feature as a landslide. (2) Dating the landslide. (3) Showing that the landslide was triggered by earthquake. - Interpreting an earthquake origin for landslides. - Slope-stability analysis Interpreting results of paleoseismic landslide studies.

Identifying surface features as landslides and classification Identifying landslides Varnes (1978)

Identifying landslides (1) Disrupted slides and falls (2) Coherent slides (3) Lateral spreads and flows

Dating the landslide Paleoseismic landslide analysis involves three steps (1) Identifying a feature as a landslide. (2) Dating the landslide. (3) Showing that the landslide was triggered by earthquake. - Interpreting an earthquake origin for landslides. - Slope-stability analysis Interpreting results of paleoseismic landslide studies.
