• The Hyogo-ken Nanbu Earthquake of January 17, 1995 caused severe damage to buildings, highway bridges, railways, lifeline systems, port facilities, and so on. This event is the first instance in which engineering structures which were designed for the highest seismic forces in the world have been subjected to such destructive ground motions. This paper shows several calculated response spectra for the Kobe record together with the Sylmar record obtained during the Northridge Earthquake, which occurred on exactly the same day of 1994. Comparing these response spectra with those for previously obtained historical earthquake records, extremely high damage potential is revealed for near field earthquake ground motion. Urgent retrofit of old structures and re-examination of present seismic design codes are essential.
