Source Mechanism and Focal Deth
Source mechanism of the June 6, 2003, Kentucky, earthquake determined by
using seismic signals recorded at regional distances (from 59 km to 463 km).
Waveform data are used to determine focal depth and source mechanism
parameters using moment tensor inversion method.
This is a preliminary results. Source mechanism indicates predominantly strike-slip
motion along steeply dipping fault planes striking 250 or 345 degree.
Source depth of 0.5 km fits the observed records best.
Data source: broadband stations of the regional seismographic networks
in the Central United States.
