Short summary
We compute a velocity model of the crust and uppermost mantle of southern North America, Mexico and the Caribbean. We use a recent technique based on "ambient noise" (or continuous seismic records) and a traditional one using earthquakes. Both techniques, together with the increased number of seismic stations in the region, allow us to obtain greater resolution than previous works. Some of its applications are to localize regional earthquakes and simulate ground motions.
