  abstract = {{T}he 2023 {M}w 7.8 southeast {T}ürkiye earthquake was recorded by an unprecedentedly large set of strong?motion stations very close to its rupture, opening the opportunity to observe the rupture process of a large earthquake with fine resolution. {H}ere, the kinematics of the earthquake source are inferred by finite?source inversion based on strong?motion records and coseismic offsets from permanent {G}lobal {N}avigation {S}atellite {S}ystems stations. {T}he strong?motion records at stations {NAR} and 4615, which are the closest to the splay fault ({SPF}) where the rupture initiated and which were previously interpreted to contain the signature of supershear rupture speeds, are successfully modeled here by a subshear rupture propagating unilaterally to the northeast. {O}nce the rupture on the {SPF} reaches the east {A}natolian fault ({EAF}), it propagates on the {EAF} bilaterally, extending about 120 km northeast and 180 km southwest. {T}o the south, the depth extent of the rupture decreases, as it passes a bend of the {EAF}. {A}lthough the rupture velocity remains globally subshear along the {EAF}, we identify three portions of the fault where the rupture is transiently supershear. {T}he transitions to supershear speed coincide with regions of reduced fault slip, which suggests supershear bursts generated by the failure of local rupture barriers. {T}oward the southwest termination, the rupture encircles an asperity before its failure, which is a feature that has been observed only on rare occasions. {T}his unprecedented detail of the inversion was facilitated by the proximity to the fault and the exceptional density of the accelerometric network in the area.},
