Point‐Source Inversion of Small and Moderate Earthquakes From P‐wave Polarities and P/S Amplitude Ratios Within a Hierarchical Bayesian Framework: Implications for the Geysers Earthquakes

Shang, Xueyi; Tkalčić, Hrvoje


Characterizing seismic moment tensors of small‐ to moderate‐magnitude earthquakes (i.e., 2.5<M<4.0) still represents a challenge in observational seismology. To address this problem, inversion methods based on fitting the first‐motion polarity and/or the amplitude ratios of the recorded waves have been designed, and where possible, the full waveform inversions were also used. The inversions that include a combination of subsets of data are desirable, but the weighting of each subset is...[Show more]
