3D Slab subduction geometry beneath Peru

This representation is based on a three-dimensional compilation of diverse types of seismic data whose allow to approximate to the surface of the slab subduction geometry in the peruvian zone. This model is based on a probabilistic non-linear fit to data from a combined catalog consisting of several independent data sets - historic earthquake catalogs, CMT solutions, active seismic profiles, global plate boundaries, bathymetry and sediment thickness information. 

The colored dots correspond to subduction earthquakes taken forn the Engdalh and Villasenor catalog. This view  NE-SW shows the complex geometry of the slab .... more comments... later....
