A landslide-induced flow failure caused 15 residents dead,and 24 houses buried during aTyphoon Aere in 2004. The landslide mechanism by a GIS spatial analysis was studied for clarifying thereasons attributed to the catastrophic hazards for geological,hydrological,and topographical characteristics.The evacuation and rescue response for the hazards are being discussed for enhancing the emergency responsein mountainous areas during harsh climatic conditions. After analysis,it was later found that the landslide wasassociated with post-seismic behaviour,torrential rainfalls,steep slopes and unfavorable geological conditions.More attention to the earthquake-induced slopeland ground surface cracking is needed during post-seismicrainfall events.
