Abstract
A deterministic seismic hazard map of Japan using the concept of maximum credible earthquakes (MCE's) is developed for engineering. Seismogenic mapped faults on land in Japan, which may produce a significant earthquake, are used for seismic sources. An appropriate attenuation relationship of peak rock accelerations (PRA's) for this analysis is selected after comparing five published attenuation studies. The horizontal PRA's are obtained by applying the estimated MCE magnitude to the attenuation relationship. The median PRA contours for 0.7g, 0.5g, 0.3g, and 0.1g (g: acceleration due to gravity) levels are shown in the seismic hazard map.
