LandTech’s PST methodology can be used even for local scale engineering geophysics projects. In this case we decrease the grid spacing of the installed sensors in order to increase the seismic ray coverage. Below we present a case where the problem was to locate the bedrock basement and possible faults in the construction site of a 3.5Km cable suspended bridge.
