N2 - As a seismic risk evaluation, Probable Maximum Loss (PML) is mainly used as an index and its most general definition is 90% non-excess loss by the earthquake which occurs 10% excess probability in 50 years, but it is not enough clear so that the result has been different by the one who calculates. We evaluated 9 sites in Japan and found that PML differs when we evaluate a point where there is a strong impact by the active fault whether we use the average or maximum case of the seismic hazard data released by J-SHIS. By using the data of 2% excess probability, we can get a result which has less difference between the average or maximum case of the 10% excess probability and what is more, to evaluate base-isolated buildings, 2% excess probability would be a better index to indicate the effectiveness comparing the seismic design buildings.
