  abstract = {{A} new interpretation is proposed for the 2010 {J}ia-{S}hian earthquake ({M}w 62) which occurred on {M}arch 4, 2010 in southwestern {T}aiwan. {A}mong the few tens of {CGPS} stations which recorded the mainshock at a distance less than 50 km we identified a few stations displaying, horizontal displacements in disagreement with the dominant pattern of horizontal coseismic motion. {B}ased on this observation, we find that a secondary rupture plane explains these peculiar motions and helps improving the modeling of the overall set of {CGPS} stations. {W}e also model the teleseismic and strong-motion records to refine the rupture model. {F}inally, we obtain the slip distribution on a two-fault model by the joint inversion of all three datasets ({CGPS}, teleseismic, and strong-motion). {T}he main fault plane is consistent with previous studies. {I}t corresponds to a {N}311 degrees {E} fault dipping 33 degrees to the {NE}, with left-lateral-reverse oblique slip, likely related to the {C}hishan transfer fault zone ({CTFZ}). {W}e find that the earthquake started with a sharp slip patch localized at the hypocenter. {T}he secondary rupture plane is a {N}20 degrees {E} thrust fault related to the {L}ungchuan anticline. {F}aulting on the main {NW}-{SE} plane during the {J}ia-{S}hian earthquake and"stress inversions from previous studies both suggest a direction of maximum horizontal compression oriented {NE}-{SW} in the area of the earthquake, very different from the dominant {NW}-{SE} compression direction in {T}aiwan. {W}e propose that such a variation can be related to a stress deviation in the immediate vicinity of the {CTFZ}, in a similar way as observed along the {S}an {A}ndreas {F}ault in {C}alifornia. {O}n the other hand, rupture on the secondary fault plane associated with the {L}ungchuan anticline appears to be compatible with the dominant compression in {T}aiwan.},
