The subduction geometry of the Nazca plate beneath the northern termination of the Andes is complex, particularly under the Choco basin. Based on the spatial distribution of hypocenters and the interpretation of focal mechanisms, we sought to refine the geometry and kinematic model of the subducting lithosphere. For this purpose, we relocated nearly 480 seismic events reported by Colombian National Seismic Network from 1996 to 2016 at depths of 0 - 180 km with local magnitudes between 3.0 and 6.5 using absolute and relative location techniques. Our results showed an apparently continuous Nazca plate along the Colombia-Ecuador trench, which subducts under the South American plate with a slight increase in the subduction dip angle in a north-...
