What is Seismic survey?
Seismic refraction and reflection methods measure the transmission of sound waves through the subsurface generated using a hammer blow or explosive energy source. Individual subsurface layer depths and thickness can be calculated based on the analysis of sonic wave arrival times.
Typical applications of seismic surveying include:
* Depth to water table,
* Depth to bedrock,
* Subsurface stratigraphy,
* Locating paleochannels,
* Identifying faults and fracture zones.
