Retrieval of earthquake source parameters in inhomogeneous anisotropic mediawith application to swarm events in West Bohemia in 2000
… assume isotropic rock properties. By means of moment tensors, equivalent forces acting at the source are used to explain the radiated wavefield. Conversely, seismic anisotropy, i.e. directional dependence of elastic properties, has been observed in the earth's crust and mantle such as in West …

The Mechanisms and Triggering of Earthquakes in the Ridge-Transform Environment
… boundary. In addition, we calculate regional moment tensors for ~30 of these events, and find that the majority are right-lateral strike-slip events consistent with observed transtensional plate motion. Chapter 2 investigates the relationship between tides and ~3500 microearthquakes recorded …

Investigations of Anomalous Earthquakes at Active Volcanoes
… Two seismicity catalogs from the Global Centroid Moment Tensor (CMT) Project are used to search for further examples of shallow earthquakes with robust vertical-CLVD focal mechanisms. CMT solutions for approximately 400 target earthquakes are calculated and 86 vertical-CLVD earthquakes are …

Shallow and deep deformation in northern Apennines region using seismological data
… deformation has been studied using seismic moment tensors information. For our purpose we used the methods described in Arvidsson and Ekstrom (1998) that allowing the use in the inversion of surface waves [and not only of the body waves as the Centroid Moment Tensor (Dziewonski et al., 1981) …

Source Parameters and Tectonic Setting of the 2017 St. Elias Earthquake Sequence near the Southern Terminus of the Eastern Denali Fault, Northwestern Canada
… were followed by more than 2,700 aftershocks. Moment-tensor inversion of the mainshock signals shows that the initial event produced reverse slip on a steeply dipping fault with a NW-SE strike direction, while the second produced left-lateral strike-slip on a near-vertical fault with an E-W …
