... of research on velocity changes has been mainly placed on co‐ and postseismic velocity changes of large earthquakes, but small‐ and medium‐sized earthquakes have rarely been studied. On 16 May 2018, an M s  4.5 earthquake occurred in Shimian County, China, in the northern Anninghe fault. Based...

... the fault geometry and coseismic slip distribution of the 2022 M w 6.6 earthquake in Sichuan, China. The dip of the best‐fitting model is 68°. The rupture of the 2022 Luding earthquake is dominated by northwest strike‐slip movement, mainly concentrated over a length of about 20 km above a depth of 15 km...

... occurrence mechanism is to maximize the resolution of the foreshock characteristics by waveform‐based earthquake detection and location. Here, we apply the match and locate method to scan continuous waveforms 30 days before and 44 days after the 2018 M L 4.0 Shimian earthquake in Sichuan, China, and obtain...

... and the corresponding model selection rules to an actual earthquake catalog in the Shimian–Mianning–Xichang region in southwest China. The results show that the Gutenberg–Richter magnitude–frequency b ‐values, converted from the moment‐frequency β values, are quite different from results obtained by previous studies...

.... Moreover, in Sichuan and Yunnan, China, ∼85% of the phase arrival‐time data have less than a 0.1 s difference for P wave and less than a 0.2 s difference for S wave between automatic picks using deep learning methods and manual picks ( Liao, Zhang, et al. , 2021 ). Furthermore, transfer learning can...

... dead and 25 missing. Using regional and global seismic recordings, we integrate the multiple‐point‐source analysis, finite‐fault inversions, and backprojection imaging to investigate in detail the rupture process associated with the 2022 Luding, China, earthquake. Our results show that this event...
