Some basic analytical models to compute surface deformations in elastic half-space. All codes are pure Matlab/Octave vectorized language.
Point source in elastic half-space, approximation for sphere of radius a << f to compute displacements, tilt and strain at surface [Mogi, 1958].
Penny-shaped crack in elastic half-space, approximation for h/a >> 1 to compute displacements at surface [Sun, 1969].
Rectangular dislocation in elastic half-space to compute displacements, tilt and strain at surface [Okada, 1985].
Rectangular dislocation in elastic half-space to compute gravity and elevation change at surface [Okubo, 1992]
Three mutually orthogonal point tensile dislocations in elastic half-space, approximation for inflated/deflated sill, dyke, pipe or any ellipsoid in the far-field [Nikkhoo et al., 2017]
Compute Doodson tidal wave components.
