Abstract

The strong earthquake struck on 12 May 2008 destroyed numerous houses in Wenchuan, Sichuan, China. This earthquake escalated the scale of existing geological disasters, undermined the stability of earthquake-prone zones, and triggered landslides and many other hidden disasters. In addition, many aftershocks and heavy rainfalls have prompted secondary disasters and consequently, the actual damages have been doubled in terms of scale and magnitude. Since some regions there are no longer appropriate for people to live, temporary housing and post-disaster reconstruction are badly needed. Recent advances in remote sensing and geospatial technologies have promoted their successful applications in siting engineering. Because of different research backgrounds, geological disasters and vegetation density were rarely incorporated as primary parameters for siting assessment. Based on the principles of avoiding active faults and encouraging synthetic prevention of geological disasters, we performed a locating analysis using part of the Wenchuan County as a case. Six major parameters were used to build a siting model, including geological disasters, vegetation index, stream systems, faults, terrain slope, and elevation. The results show that the proposed method can provide useful information for decision-making in the selection of temporary housing and post-disaster reconstruction.
