Abstract

In order to reduce damage by landslides, an early warning system can be one of the effective countermeasures based on the early detection of landslide occurrence and, therefore, preemptive early evacuation of residents from a landslide prone area. Early detection of landslide indication in a broad natural terrain can be performed by monitoring of rainfall in real time or in near-real time. Based on the real time rainfall data, this study suggested a method to warn of landslides by the application of a tracking line of rainfall. The method makes it possible to set up warning criteria of landslides considering local rainfall characteristics in the summer. This study suggested a method of landslide early warning based on the regional rainfall conditions.
