Description:
A decade ago, numerous interpretations cast doubt on the possibility that the Cocos plate extended continuously or had a tear underneath central-southern México, dividing Cocos into Central Cocos and South Cocos. Recent evidence reveals the tear model as the most feasible. We present a description of the plate behavior in the region, supporting the tear's presence, based on a 3D P-wave teleseismic tomography inversion of 7,043 first arrivals. The velocity models show discontinuous regions and the evolution of a tear perpendicular to the Mesoamerican trench towards the country's southeast
