Abstract: Landslide is one of the most of serious disasters in Aceh. One of the worst event occurred in Paya Ateuk village, South of Aceh in May, 30th 2008. To study the potential of subsequent landslides in the region, we have measured geophysical methods: Very Low Frequency (resistivity mode VLF-R; frequency of 18.3 kHz and 22.2 kHz). The magnetic field data (H) and electric field (E) was measured by 10 profiles with length between 90-250 meters. The length spacing of the profiles made between 20-50 meters and station spacing of 10 meters. Apparent resistivity and phase data calculated from the measured electric and magnetic fields. Based on the apparent resistivity mapping in the study area, we have been able to located the risk landslides area. The zone is indicated by low resistivity values.


Keywords:  Landslides, geophysical methods, VLF-R.
