| The calculated values of annual probability of assumed seismic wave acceleration andsensible vibration in a random place acceleration to be able to be used as an earthquakeproofing index considering about conditions environmentally characteristic in the region．However，the estimated value is greatlyaffected by regional conditions，the number of earthquake information，and measured seismic wave acceleration records，so additional earthquake information in future and further investigation to make the system more precise as the forecast will have less probable errors are necessary． |
