Abstract:

In this paper, based on waveform comparision of theoretical seismgrams with four teleseismograms recorded by SBA(New Zealand) and SPA(U.S.A) of WWSSN.It shows that the crustal thickness beneath South Pole is about 45km, double layered structure.That crustal thickness below Ross Sea Beach is single structure, about 24km.At the depth of 350-450km it presents low velocity layer. The above results indicated different tectonic characteristics in both sides of Antarctic Transantarctic Mountain.
