The objective of this project is to estimate the location of a large under- ground vibration source through seismograph readings. To achieve this, fre- quency analysis of the three-dimensional seismograph readings is conducted. Specifically, The Fast Fourier transform, spectral averaging, and spectral fil- tering techniques were used. Averaging of the spectral decompositions of the seismograph realizations reveals the frequency the signals are centered about. A gaussian filter, centered about the primary frequency, is then used to esti- mate the location of the vibration source for each seismograph reading.
