Teleseismic Epicentre Locations from Arrival Times at Regional Networks

Arrival time reportings from local and regional networks can be used for preliminary epicentre location of teleseismic events via slowness and azimuth estimation. Robust techniques for doing so are presented, and their relative performance tested on ISC listed P arrival times of Fennoscandian statio...
