| Abstract | The study was conducted at the Blang Bintang Sanitary Landfill in Aceh, Indonesia using P- and S-wave seismicrefraction methods. The aim was to investigate the ground subsurface lithology. Arrival time against distance was plotted for Pand S-wave seismic refraction. Two ground subsurface boundaries were identified with three layers: top soil, highlyweathered/weathered bedrock, and bedrock with Vp and Vs values of 480?730 m/s and 256?342 m/s, 1627?2010 m/s and525?691 m/s, and 2500?3588 m/s and 836?840 m/s, respectively. The plots were also capable of indicating a fractured/fault zonewith Vp and Vs values of 480?730 m/s and 256?691 m/s, respectively. Seismic refraction tomography of the P- and S-waves arecapable of classifying the ground subsurface into four types of lithology: top soil, highly weathered bedrock, weathered bedrock,and bedrock with Vp and Vs values of <720 m/s and <450 m/s, 720?1620 m/s and 450?650 m/s, 1620?2800 m/s and 650?840m/s, and >2800 m/s and >840 m/s, respectively. The fractured/fault and landfill zones were identified by seismic refractiontomography with Vp and Vs values of <720 m/s and <450 m/s, respectively. The seismic refraction of Vp and Vs have their ownstrengths because each of them considers different types of moduli and different velocity calculations. |
