Geophysical Survey
A geophysical survey is a method of investigating the Earth’s subsurface by measuring and analyzing physical properties like electrical resistivity, seismic wave velocity, magnetic susceptibility, and electromagnetic conductivity
- Seismic Refraction Test (SRT) using specialized equipment imported from PASI Geophysics, Italy
- Down-Hole Seismic test (DHST) using customized equipment from Olson Engineering, U.S.A.
- Cross-Hole Seismic test (CHST) using customized equipment from Olson Engineering, U.S.A.
- Spectral Analysis of Surface Waves (SASW)
- Multi-Channel Analysis of Surface Waves (MASW)
- Parallel Seismic Test using customized equipment imported from Olson Engineering, U.S.A.
- Electrical resistivity imaging (ERI) and tomography
- Ground-penetrating radar (GPR)

Result
These surveys are used to map geological structures, locate resources (like minerals and groundwater), and assess potential hazards. They are non-destructive, meaning they don’t require excavation to gather information.
