RPNet: Robust P-Wave First-Motion Polarity Determination Using Deep Learning

Seismological Research Letters
Abstract We present RPNet, a robust deep-learning model for P-wave first-motion polarity determination aimed at deriving earthquake focal mechanism solutions. RPNet integrates advanced deep-learning techniques, including inception modules, attention mechanisms, and Monte Carlo dropout, to improve prediction accuracy and stability with ...

P-wave First-Motion Polarity Determination Using Order Statistics and Entropy Theory (POSE) with Applications to Southeastern Tibetan Plateau

Journal of Geophysical Research: Solid Earth
Abstract The Focal Mechanism Solutions (FMSs) of small earthquakes provide valuable insights into crustal structure and stress conditions, while its reliability is limited by the accuracy of first‐motion polarity determination, which remains challenging.

Joint Inversion of Regional Waveform, First-Motion Polarity, and Synthetic Aperture Radar Surface Displacement for the Fourth and Sixth North Korean Declared Nuclear Explosions

Bulletin of the Seismological Society of America
ABSTRACT This study analyzed the Democratic People’s Republic of Korea’s (DPRK) fourth (DPRK4, 6 January 2016 Mw 4.49) and sixth (DPRK6, 7 September 2017 Mw 5.2) declared nuclear tests, employing a joint seismic and Interferometric Synthetic Aperture Radar (InSAR) inversion to improve understanding of these events and enhance moment ...
