Schematic diagram of a fault buried in a domain of interest, Ω , embedded in a quasi-half-space. The embedded domain has a boundary consisting of a free surface Γ0 and an artificial boundary Γ . The half-space has a boundary consisting of Γ0 and a remainder Γ∞ . The unit outward normal to the domain boundary is denoted by |$\hat{\mathbf {n}}$| . The domain Ω contains a fault surface Σ with unit normal |$\hat{\boldsymbol{\nu }}$| .
