This earthquake caused the death of more than two thousand people, severe property loss, and a large number of landslides. A large amount of landslide data and strong motion records were produced by the Chi-Chi earthquake. This research establishes a landslide database and data warehouse collected from the Chi-Chi earthquake in a Geographic Information System (GIS). Using the powerful data-processing function and spatial analysis ability of GIS and Decision Tree Data Mining modeling, we have identified the possible mechanisms that induce landslides and produced an map of landslide susceptibility. Verification proved that the research result is good and the methods used by this research suitable for the forecast of risk assessment of landslide hazard triggered by earthquakes. The findings can be used as a tool for disaster mitigation decision support.254171 bytesapplication/pdf資料探勘地震山崩地理資訊系統決策樹演算法Data miningGeographic information systemDecision treeEarthquake-induced landslidejournal articlehttp://ntur.lib.ntu.edu.tw/bitstream/246246/281534/1/0036_200406_6.pdf
