Initial Results from the MASE Central Mexico Seismic Experiment

Robert W. Clayton

The MASE seismic experiment has revealed an almost unique subduction scenario
in which the subducted slab is underplating the continental crust for some 250
km without coupling to it. The slab dives into the mantle near the Trans
Mexican Volcanic Belt and is truncated at a depth of 500 km, which supports the
hypothesis of a west to east tear in the slab approximately 7 Ma. In this talk
I will describe the experiment, these initial results, and some proposed future
work.
