Detection capability of teleseismic events recorded at Syowa Station, Antarctica: 1987-2007
A phase identifying procedure for the teleseismic events at Syowa Station (69.0°S, 39.6°E), Antarctica has been carried out since 1967 by use of analog and digital records of short- and long-period seismometers. After the establishment of an INTELSAT telecommunication link, several kinds of digital...
