Strong motion data were recorded in the vicinity of the source area during the Hyogoken-nambu earthquake, 05 : 46 January 17,1995. Observation sites have been established by the Committee on Earthquake Observation and Research in the Kansai Area (CEORKA). Two of them are deployed in Kobe which fault rupture reached during the mainshock and which are adjacent to a heavily damaged area. The horizontal maximum velocity recorded at a rock site, Kobe University, was 55 cm/s. Strong motion data also was recorded at the Japan Meteorological Agency (JMA) site in the central area of Kobe (horizontal max. 818 cm/s^2). The Kobe City Office recorded horizontal max. 341 cm/s^2 at a reclaimed island. In this paper, seismograms in the source area recorded by CEORKA are shown and compared with the data recorded by the JMA and Kobe City Office.
