Borehole seismic measurements and their resultant images and properties can provide further detailed pictures of the subsurface as shown in two cases here (FORGE geothermal site and West Texas). The advent of fiber-optic vibration measurements (DAS) in boreholes can increase the usefulness of in situ seismic recording by having many more channels in various geometries that can record a variety of wavetypes to enhance subsurface interpretation and characterization
