Focal mechanisms and seismic moments of large earthquakes in the Antarctic Peninsula-Drake Pasage region (abstract)
P(論文) Fault plane solutions and seismic moments of four largest shallow events which occurred in the Antarctic Peninsula-Drake Passage region were redetermined by the moment tensor inversion method (FITCH et al. : J. Geophys. Res., 85,3817,1980) for body waves on WWSSN long-period records. The June...
