Moment tensors: decomposition and visualization

Popis výsledku v původním jazyce

he moment tensor is a widely accepted quantity for studying seismic sources. It is evaluated for earthquakes on all scales from acoustic emissions to large devastating earthquakes. In order to understand physical processes at the earthquake source, the moment tensor is decomposed into double-couple (DC), isotropic (ISO), and compensated linear vector dipole (CLVD) components. High percentage of DC indicates shear faulting in isotropic media, and high percentage of ISO indicates an explosive or implosivesource. A combination of positive/negative ISO and CLVD is produced by tensile/compressive faulting. The type of the source can be visualized using the source-type plots; among them, the diamond CLVD-ISO plot, the Hudson's skewed diamond plot, and the Riedesel-Jordan plot are in common use. In anisotropic media, the physical interpretation of the moment tensor is not straightforward, and the decomposition of the moment tensor must be substituted by that of the source tensor.
