Webb1 juli 2024 · In terms of seismology, this technology is showing high sensitivity, robustness and efficiency in the detection of small earthquakes and phase picking (Ross et al., 2024; Wang et al., 2024; Zhu et al., 2024; Zhu and Beroza, 2024; Zhao et al., 2024a, Zhao et al., 2024b), and thus playing a more and more important role in seismic data processing ... Webb9 aug. 2014 · Abstract. We develop a set of algorithms for automatic detection and picking of direct P and S waves, as well as fault zone head waves (FZHW), generated by earthquakes on faults that separate different lithologies and recorded by local seismic networks. The S-wave picks are performed using polarization analysis and related filters …
