Ramp thrusts offset the seafloor and sole out to an east-dipping décollement, indicating ongoing westward-vergent tectonic shortening. New traveltime tomographic results image a slab of oceanic lithosphere descending from the Atlantic domain of the Gulf of Cadiz, passing through intermediate-depth (60–120 km) seismicity beneath the westernmost Alboran Sea, and merging with a region of deep-focus earthquakes 600–660 km below Granada, Spain. Together, these new data provide compelling evidence for an active east-dipping subduction zone.
