To measure seismic waves 3D (3D Seismic Survey) survey is a method of obtaining geological structures beneath the soil surface Geophysics by sending waves into the ground surface with a point object (Explosive Method), which originated in areas sensitive to environmental and social use of the wave generator size 1.5 kg per hole. Best in the area, which is a space exploration and away from sensitive areas and environmental society, will use the wave generator 2-3 kg per pit is seismic wave origin.
