Double-Difference Seismic Event Relocation: A Study of the Applications and Limitations of the Relocation Problem
Earthquake relocation provides refined earthquake catalogs based on additional considerations or data beyond the initial earthquake location estimates. Double-difference relocation, in particular, utilizes the assumption that ray paths in close proximity to one another will pass through a similar …

Source Parameters and Tectonic Setting of the 2017 St. Elias Earthquake Sequence near the Southern Terminus of the Eastern Denali Fault, Northwestern Canada
… to the eastern Denali fault (EDF). These double mainshock events 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 …

Micro-seismic observations in Leeu Gamka, Karoo, South Africa
… fall within a one square kilometre block). Double-difference relocation resolved the hypocentres onto a structure with an apparent NW - SE orientation, consistent with large-scale fabric that can be recognised in satellite imagery. The focal mechanisms display strike-slip faulting with the …
