Fault shape effect on SH waves using finite element method

Abstract

AbstractIn this paper, we analyse how the combination of fault zone shape and material properties affects the propagation of seismic waves in a two-dimensional domain. We focus on SH wave propagation through several faults with different thicknesses and bending radii, but the theory is easily generalized to the three-dimensional case. We show how the density of energy released is mostly a function of the radius and does not depend on the velocity inside a fault zone.
