Development of microcontroller-based landslide early warning system

As reported by the National Disaster Risk Reduction Coordinating Council of the Philippines, from the year 2010–2015, landslide is the third most recurring geohazard, next to floods and earthquake. Casualties caused by landslide constitute 1.55% of the total casualties during the same time span. Due to fact that a landslide early warning system is not considered, and the practice of only secluding the public from defined landslide prone areas, the safety of the general public is always at risk. The objective of this paper is to develop a landslide early warning system that utilize rain gauge and an intelligent accelerometer/inclinometer for interception of possible occurrence of landslide. With the help of PHIVOLCS and PAGASA calibration for the standard level of measurement were established: (l)rainfall amount,(2) angular displacement and (3)ground movement. With the factors observed it is expected to deliver an effective landslide early warning system that can intercept an impending landslide whether it is earthquake-induced or rain-induced.
