Computation of static co-seismic displacements due to a dislocation-type deformation in a half-space
Description: This exact solution is often used to construct co-seismic displacements due to an underwater earthquake. These displacements are then used to construct in some way an initial condition for tsunami propagation codes.
For more details, please, refer to the original Okada paper:

because i can see it anywhere
Thanks a lot for your comment. I found your script after the submission. In tsunami generation problems we look for the kinematics of the bottom displacements. Consequently, only the displacements field is computed.
Nice and effective function.
If you need open mode fault and compute all the tilt and strain components, see my submission at http://www.mathworks.com/matlabcentral/fileexchange/25982
