Tens of thousands of landslides were triggered by May 12,2008 earthquake over a broad area.The main purpose of this article is to apply and verify earthquake-triggered landslide hazard analysis techniques by using weight of evidence modeling in Qingshui(清水) River watershed,Deyang(德阳) City,Sichuan(四川) Province,China.Two thousand three hundred and twenty-one landslides were interpreted in the study area from aerial photographs and multi-source remote sensing imageries post-earthquake,verified by field surveys.The landslide inventory in the study area was established.A spatial database,including landslides and associated controlling parameters that may have influence on the occurrence of landslides,was constructed from topographic maps,geological maps,and enhanced thematic mapper(ETM+) remote sensing imageries.The factors that influence landslide occurrence,such as slope angle,aspect,curvature,elevation,flow accumulation,distance from drainages,and distance from roads were calculated from the topographic maps.Lithology,distance from seismogenic fault,distance from all faults,and distance from stratigraphic boundaries were de-rived from the geological maps.Normalized dif-ference vegetation index(NDVI) was extracted from ETM+ images.Seismic intensity zoning was collected from Wenchuan(汶川) Ms8.0 Earthquake Intensity Distribution Map pub-lished by the China Earthquake Administration.Landslide hazard indices were calculated using the weight of evidence model,and landslide hazard maps were calculated from using different controlling parameters cases.The hazard map was com-pared with known landslide locations and verified.The success accuracy percentage of using all 13 con-trolling parameters was 71.82%.The resulting landslide hazard map showed five classes of landslide hazard,i.e.,very high,high,moderate,low,and very low.The validation results showed satisfactory agreement between the hazard map and the existing landslides distribution data.The landslide hazard map can be used to identify and delineate unstable hazard-prone areas.It can also help planners to choose favorable locations for development schemes,such as infrastructural,buildings,road construc-tions,and environmental protection.
