All seismic methods measure the travel-time and frequency of elastic waves as they propagate through the subsurface. The methods commonly used in shallow geophysics involve using an impact source (hammer, weight drop, explosive source) to generate the seismic wave and recording the arrival of the waves with a seismograph and a series of ...

Seismic Reflection Reveals What is Under the Surface. We use seismic reflection as a method of geophysical exploration that uses the principles of seismology to estimate the properties of the Earth's subsurface from reflected seismic waves. The method requires a controlled seismic source of energy, such as dynamite, a specialized ...

Multichannel Analysis of Surface Waves technique- in active MASW 1D/2D/3D and passive MAM/ReMi 1D versions, bases on seismic S-waves analysis included in dispersive Rayleigh waves. A characteristic feature of the Rayleigh wave is that it represents about 70% of the total elastic energy waves recorded during the measurement. S-wave, whose ...

Seismic refraction is a geophysical method used to determine the seismic compression-wave (P-wave) velocity structure of the subsurface. Seismic P-waves are generated on the surface, propagate through the soil and rock, and are recorded by geophones at known distances from the source. Since P-waves are the fastest portion of the ...

Refraction tomography bases on the classic seismic refraction studies. Classical refraction gives good results in the ground with relatively low variable structure and layers (which differ significantly in velocities of seismic waves). In contrast, tomography can localize more complex structures where seismic wave velocities change in ...
