Complexity of the Mw 6.3 2009 L'Aquila (central Italy) earthquake: 1. Multiple finite-extent source inversion
Original language description
Strong ground motion recordings of the Mw 6.3 2009 L'Aquila earthquake are analyzed by a newly proposed slip inversion technique. The source model consists of Multiple Finite-Extent (MuFEx) subsources. The slip amplitude, rupture velocity, rake and risetime are assumed constant within each subsource. The size and location of the MuFEx subsources have to be inferred independently from other methods, preferably those free of strong constraints (such as constant rupture velocity over the whole fault, etc);here we use two published approaches satisfying such requirement: the truncated singular value decomposition and the iterative multiple-point source deconvolution. Each MuFEx subsource is characterized by an individual set of trial nucleation points, rupture velocities and nucleation times, which are grid-searched. For each combination of these parameters, the subsources' slip is determined by the least squares approach. This procedure thus provides not only the best fitting model, but
