mechanism. Tectonic earthquakes are mostly shear slip events with a DC mechanism, while rockbursts are supposed
to have a more complex mechanism with non-DC components. Thus, the robustness of the determination of the non-
DC part is a crucial issue. It is known that a reliable estimate of non-DC is often a weak point of an inverse task using
the MT source model. The physical model of a generalized slip-the STC-resulting in a constrained MT is much more
robust in realistic situations, and gives some perspective for an answer even where the full MT inversion fails.Workplace Geophysical Institute Contact Hana Krejzlíková, kniha@ig.cas.cz, Tel.: 267 103 028 Year of Publishing 2019
