%T ANALISIS TINGKAT KERENTANAN GERAKAN TANAH DI DUSUN TULANGAN DESA NGARGOSARI KAPANEWON SAMIGALUH DENGAN PENDEKATAN GROUND SHEAR STRAIN (GSS) MENGGUNAKAN METODE MIKROSEISMIK
%X The ground motion research was conducted using a microseismic method that produces wave signals and analyzed using the HVSR method in order to obtain the dominant frequency value (f0) and amplification factor (A0) which is presented in the form of an H/V curve. This study aims to determine the value of the seismic susceptibility index (Kg), the value of the peak ground acceleration (PGA), and determine the value of the ground shear strain (GSS). Based on the GSS value and the slope of the slope, it can determine the level of vulnerability to soil movement in the Tulangan Hamlet, Ngargosari Village, Kapanewon Samigaluh. The method used in determining the potential for landslide-prone disasters is using the scoring method to classify the potential for landslide-prone areas. The landslide susceptibility level is divided into three classes, namely low, medium and high. The results of this study indicate that the value of ground shear strain (GSS) ranges from 0.11 x 10-3 to 0.85 x 10-2. When deformation occurs, the soil will experience cracks in the soil layer and landslides. The slope in the study area is classified as a moderate to very steep class. So that the Hamlet of Reinforcement includes a medium to high disaster-prone potential.
