Setup of a Landslide Monitoring System on the Philippine Island of Leyte Near the Village of Malinao (Municipality of St. Bernard)

This article describes the setup and first results of a landslide monitoring system near the village of Malinao, municipality of St. Bernard on the Philippine Island of Leyte. The monitoring system combines wireless sensor network (WSN) technology with low-cost but precise micro sensors (MEMS). The system was developed in the framework of the joint project “SLEWS—A Sensor-based Landslide Early Warning System” that deals with the development of a prototype Alarm- and Early Warning System (EWS) for different types of landslides. The sensors integrated in the WSN are acceleration sensors, tilt sensors and barometric pressure sensors. The system was installed in November 2010 in a landslide prone area near the village of Malinao. For longer data transmission of about 15 km the SLEWS-System was combined with the already existing WLAN-based monitoring system for Flood Early Warning (FEWS) from the Deutsche Gesellschaft fur Internationale Zusammenarbeit (GIZ).
