Mogi: point source of dilatation in elastic half-space
The Mogi [1958] model allows to calculate analytic solution for surface deformation due to a point source in an elastic half-space. This model is widely used to simulate ground deformation produced by local perturbation like volcanic magma chamber. It computes displacements, tilt and strain in a polar space, due to a volume variation at depth [Anderson, 1936] or an isotropic pressure variation in a spherical source [Mogi, 1958].
The proposed Matlab script is a literal transcription of Mogi's simple equations, extended to non-isotropic medium (Poisson's ratio different from 0.25). All parameters can be vectorized. See help for syntax, and script comments for details.
