Abstract: To investigate the characteristics of the 2017 M_L4.9/Ms4.4 earthquake sequence in Muli, Sichuan, an end-to-end framework, ranging from raw continuous seismic waveform data processing to seismic phase detection, earthquake event identification, and earthquake location, was constructed based on lightweight artificial intelligence methods, template matching techniques, and earthquake location methods. This system processed raw waveform data from 28 stations within a 60-km radius of the epicentral area between September 1 and 30, 2017, reconstructing a high-resolution seismic catalog containing 9, 252 foreshocks, mainshocks, and aftershocks. Based on focal mechanism solutions of 43 M_L≥2.5 earthquakes, we conducted a comprehensive analysis of the seismicity patterns. The refined catalog exhibits enhanced consistency with Gutenberg-Richter magnitude-frequency statistics and clearly delineates spatiotemporal evolutionary features. The seismic sequence occurred within a complex NW-SE trending strike-slip fault system bounded by theJinpingshan Fault. The bilateral expansion of events from the mainshock toward the NW and SE, preliminarily attributed to driving by afterslip.
