The 1D velocity model that we propose consists of six layers with velocities of Vp = 5.66 km/s for the first layer, to 7.92 km/s for the last one. This model defines the boundary between the crust and mantle (Mohorovicic) at a depth of 45 km below our study area. The earthquake relocation shows a better distribution of hypocenters in surface and depth and also shows a reduction of 35% in the rms values. This model constitutes a major contribution to the knowledge of the structure velocity in northern Peru and can be used as a reference in software for earthquake location, as well as in seismicity, tectonics and seismic risk studies in northern Peru.
