A wedge-shaped graben extension mechanism for the 2025 Dingri earthquake involved two graben-bounding faults, highlighting that early postseismic deformation is mainly driven by shallow afterslip and viscoelastic relaxation, with the afterslip spatially complementing coseismic slip, according to integration of field observations, geodetic and seismic data.
