a Map showing locations of the surface ruptures and field photos along (b, c) the CRF and (d, e) the LVF. f Coseismic GNSS displacements for the mainshock near Chihshang. g North and vertical component of the GNSS position time series at station TAPE (30 m west of the LVF), TAPO (540 m east of the LVF) and CE2A (2.3 km east of the LVF)56. FS foreshock, MS mainshock. The northward and upward coseismic motion of TAPO during the mainshock deviates from the motions of other stations in the hanging wall of the CRF (with southwestward and upward coseismic motion), as well as CE2A located further east (with northwestward and downward coseismic motion). This anomalous motion suggests the near-field interference from the LVF, most likely a coseismic shallow slip.
