Seismic – Engineering


Geophysics

Seismic methods measure the elastic properties of soil and rock that are a function of the physical properties such as seismic velocity, density, and shear modulus. Collier employs various types of seismic methods to various problems including: reflection, refraction, tomography, active and passive MASW, downhole and crosshole seismic, and marine applications. We are a leader in applying full wave form inversion to shallow seismic applications to map fractures, voids, and karst.
