Project: 5WTG Wind Farm in Ireland. Client: Confidential Project Description: Seismic Refraction and Surface Wave MASW Services Provided: Defining Geological Profile Both seismic refraction and surface wave MASW techniques were used to define stratigraphic boundaries at 5 turbine locations across the site. Seismic Refraction Method Seismic refraction uses seismic P-waves to locate changes in acoustic properties of the ground. Using a hammer and plate source, seismic energy is transmitted into the ground. These seismic waves will refract if they encounter a velocity change which could be caused by differences in density or lithology (soil or rock type). A portion of the wave will travel along this boundary and will eventually return to the surface as a head wave which is detected by
