Preliminary study of the tectonic structure and seismogenic environment of the M4.7 Feidong earthquake sequence on September 18, 2024 in HefeiKey points
Published 2025-06-01“…The results indicate: (1) the M4.7 Feidong earthquake sequence is concentrated around 10.5 km in depth along a NW-dipping, subvertical fault which trends NE and is approximately 5 km in length; the focal mechanism solution also reveals that the fault hosting the mainshock is a subvertical strike-slip fault, driven by the regional compressional stress in ENE-WSW; the coseismic horizontal displacement on the surface caused by the M4.7 mainshock has a maximum value close to 1 mm; (2) the regional velocity model shows significant lateral variation in vS in the source region, with the mainshock occurring in the area with higher velocity; high-resolution P-wave velocity structures obtained by full waveform inversion from active sources, and S-wave velocity structures from passive-source ambient noise tomography indicate that the mainshock occurred along the boundary between high- and low-velocity bodies, and the seismogenic fault dips NW; the deep seismic reflection profiling shows that the mainshock occurred within the Jurassic strata; (3) based on these results, we suggest the seismogenic fault for the M4.7 Feidong earthquake is either the Zhuding-Shimenshan fault, one of the major faults in the Tanlu fault zone, or a hidden fault to the east; the intersection of the NE-trending Tanlu fault zone and the WNW-trending Feizhong fault, along with significant velocity variations, likely create local stress concentrations which could have triggered the M4.7 Feidong earthquake sequence; (4) the strong aftershocks following the M4.7 Feidong mainshock did not further extend the fault rupture zone; the active period of the Zhuding-Shimenshan fault was the late Early Pleistocene to Middle Pleistocene, and the imaging results indicate that this fault does not cut through the shallow Feidong depression. …”
