A local earthquake with 20s S-P time was recorded at two seismic stations (Syowa and Tottuki) with three-component seismographs in Lutzow-Holm Bay, Antarctica in June 1987. The earthquake was located at about 170km northeast of Syowa Station. Its magnitude was estimated to be about 1.8. Other ten earthquakes of 20s S-P time were recorded by a test small tripartite seismic array in East Ongul Island during March 1987. The east Antarctic shield has been considered to be an aseismic area. It becomes clear, however, that some local earthquakes are located in the marginal area of the east Antarctic continent.
