Recent advances in geologic mapping, aftershock location, and reflection seismology allow geoscientists to image surface and subsurface structures with greater precision. These images demonstrate that earthquake ruptures typically occur along faults or fault systems that display complex 3D geometries. Poly3D, a 3D boundary element code and user interface, enables the integration of these varied data sets to constrain fault geometry and accurately models the complex geometries, limited only by data precision and computing power. Poly3D is based on the analytical solution for the elastic boundary value problem of an angular dislocation in a half space composed of a homogeneous and …

The May 13, 1995 Kozani-Grevena earthquake (Mw=6.5) is a natural laboratory for studying crustal normal fault systems. The event and its aftershocks have been well observed geodetically, seismically, and geologically, providing an opportunity to integrate data sets to create a detailed subsurface fault model and investigate triggering and deformation associated with a large normal fault earthquake. Previous modeling of the earthquake has focused primarily on single geodetic data sets (e.g. inSAR - Meyer et al, 1996, GPS - Clarke et al., 1997) and has led to conflicting subsurface fault interpretations. In order to better model the subsurface fault geometry we …
