Seismic source characterization using a Neighbourhood Algorithm

Kennett, Brian; Marson-Pidgeon, K; Sambridge, Malcolm

Description

The full characterization of a seismic source requires the specification of the hypocentre location and the source mechanism. The non-linear inversion is accomplished in two stages using the Neighbourhood Algorithm (NA), a direct search method in parameter space which is able to preferentially sample those regions with least data misfit; there are just two control parameters and no differentiation is employed. The first step is hypocentre location using a 4-D search space and a focussed search...[Show more]
