This study predicted the earthquake damage in Nagano city when the Shinanogawa-fault lines has been moved. This fault lines are located in the north area of Nagano Prefecture and serious damages in Nagano city is expected if the earthquake occurs. First, an assumed Magnitude was decided. Second, earthquake motions while shifting focal area along Shinanogawa-fault lines were simulated. Finally, we compare each focal area which is the most dangerous when the earthquake occurs by using Population Exposure to Seismic Intensity as an indicator.

This study predicted the earthquake damage in Nagano city when the Sinanogawa-fault lines has been moved. This fault lines are located in the north area of Nagano Prefecture and serious damage in Nagano city is expected if the earthquake occurs. In this research, the firstly the seismic scales and the indexes of liquefaction on the ground are predicted based on earthquake scenarios which vary in the earthquake's magnitude. The secondly, the damage points of the road network, the number of collapse in a building and the casualties are estimated.
