We use the autocorrelation of seismic noise to locate a fault zone in the near-surface at a prospective geothermal site in Singapore. Specifically, we analyse the variation in the peak frequency of autocorrelations, along with attempting to recover the zero-offset reflectivity beneath each seismic station. Our results are broadly consistent with other geophysical methods and with core from the borehole. The approach is straightforward in terms of data acquisition and processing, although we caution that there are limitations, primarily related to the interpretation of later signals that may be contaminated by multiples and the suspected breakdown in the theoretical assumptions underpinning the method.
