The upper crustal structure of the Soya Coast, Antarctica was estimated by a seismic refraction experiment which was carried out in January 1979. A surface thin layer with a P-wave velocity of 4-5km/s was derived from the traveltime analysis for the first time in East Antarctica by explosion seismology.
