Developing framework to constrain the geometry of the seismic rupture plane on subduction interfaces a priori - A probabilistic approach
G.P. Hayes, D.J. Wald
2009, Geophysical Journal International (176) 951-964
A key step in many earthquake source inversions requires knowledge of the geometry of the fault surface on which the earthquake occurred. Our knowledge of this surface is often uncertain, however, and as a result fault geometry misinterpretation can map into significant error in the final temporal and spatial slip...
