Abstract

Cross borehole seismic tomography has been the subject of intensive study as a tool for high resolution imaging. In spite of early hopes, tomographic images computed from arrival times are often poorly resolved, even where high frequency data are successfully acquired. Recent developments in processing cross borehole data have allowed us to compute new images of a geological fault that are significantly better resolved than previous images (see Figure 1). We achieve this improvement because the new method uses the seismic arrival waveform, rather than simply using the arrival times. The new images allow the fault plane to be located laterally to within a few metres.
