Abstract

Abstract:

Tens of thousands of landslides were triggered by Wenchuan earthquake. The purpose of this study was to find correlations of landslide occurrence with formation lithology, slope gradient, elevation, peak ground acceleration, and distance from seismogenic fault in two selected landslide incidental areas(A/B), using spatial analysis methods. The results show that rock groups of graphite schist and quartzite had the most concentrated landslide activities in area A, while siltstone, sandstone, and chert rock groups in area B. The landslide susceptibility levels have a positive correlation with slope steepness in both the areas. The advantage slope gradient is 44°in area A and 38° in area B. There were also relations between elevation and earthquake-induced landslide distribution. Peak ground acceleration has no positive or consistent correlation with earthquake-induced landslide occurrence, but the distance from seismogenic fault shows approximate positive correlation with landsliding. There is a higher landslide distribution area ratio on the upper plate than on the lower plate.

Key words: Wenchuan earthquake, landslide, spatial distribution, statistical analysis, geographic information systems
