SCEDC logo   Tomographic model of Southern California

This is an interactive site to view the vertical and horizontal cross sections of the tomographic model from the PhD thesis of Carl Tape.
For details, see "Adjoint tomography of the southern California crust" (Science, v. 325, p. 988-992), by Carl Tape, Qinya Liu, Alessia Maggi, and Jeroen Tromp.
The study used earthquake simulations such as the ones on the ShakeMovie website.
The wave-speed values at the gridpoints used in the simulation can be downloaded from Carl's PhD thesis homepage (Section 6 link).
For questions regarding the model please contact Carl Tape (carltape\at\gi.alaska.edu).
