| Abstract | Typhoon Morakot brought heavy rainfall caused landslides and flash floods in southern Taiwan from August 6 – 10, 2009. Rainfall is one of the primary factors causing landslides on the hillslopes during this event. In this study, we performed a statistical analysis with slope, elevation and maximum 72hour precipitation from historical rainfall records to investigate the effect of cumulative rainfall on the occurrence of landslide events during this typhoon event. The result represents that the landslide distribution after typhoon Morakot has highly correlated with the distribution of gradient and rainfall. 80% of landslides occurred in areas with slopes from 20° to 50°. Furthermore 95% landslides occurred in areas with more than 300 mm of the cumulative rainfall amount and over 40% of the maximum 72-hour precipitation of historical rainfall record. |
