SSIP Imperial Valley model provides P-wave velocities for the shallow crust in the southern Salton Trough, from the southern Salton Sea to the USA-Mexico border. The model combines travel-time observations from explosions recorded during the Salton Seismic Imaging Project (SSIP) and the IV1979 active source experiment with local earthquake recordings. The model extends from the surface to 8-km depth.
This package is intended to be installed as part of the UCVM framework, version 25.7 or higher.
The library ./lib/libivlsu.a may be statically linked into any user application. Also, if your system supports dynamic linking, you will also have a ./lib/libivlsu.so file that can be used for dynamic linking. The header file defining the API is located in ./include/ivlsu.h.

Note this e-mail address should be used for questions regarding the software itself (e.g. how do I link the library properly?). Questions regarding the model's science (e.g. on what paper is the IMPERIAL valley velocity model based?) should be directed to the model's authors, located in the AUTHORS file.
