True amplitude stacking for moment magnitude estimation of microseismic events
Original language description
We develop methodology of moment magnitude estimation for microseismic events. Our method is designed for stacking true amplitude waveforms recorded with surface array. We show that magnitude can be determined from the stack of amplitudes corrected for radiation pattern and propagation effects such as geometrical spreading, attenuation and free surface boundary. From the stack of corrected waveforms we find low frequency limit of displacement of the stack and calculate seismic moment. We show that a traditional method of estimating moment magnitude on each trace and averaging is consistent with stacking method introduced in this paper. This method can be used for much weaker events whereas traditional methodology cannot.
