Abstract
Watukumpul is an area located in central Java which has two active landslide trigger, for example, high slope and earthquake. The aim of this study was to determine the landslide potential area in Watukumpul induced by earthquake and soil slope. We used 33 microtremor measurement data analyzed using Horizontal to Vertical Spectral Ratio (HVSR) and Historical earthquake data between 1988-2018 to calculate ground shear strain (GSS) value that describes the soil dynamics condition when the earthquake occurs. The area has soil slope range between 0 0 -58 0 . The result of ground shear strain calculation ranges between 0.0004 – 0.0092. We combined the high slope and GSS value using Simple Additive Weight (SAW) method to make the landslide potential area map. The result of the SAW method showed that the area has medium and high landslide potential.
