We propose a method to estimate amplification factor at an arbitrary point to obtain the spatial distribution of JMA seismic intensity including nonobservation sites. The amplification factor of JMA seismic intensity is estimated using the records from a high-density strong motion network. We compare the seismic intensities observed at some staions in Kanazawa city during the past earthquakes with those estimated calculated by seismic intensity at a reference station and amplifaication factor of each site. The predicted values were in good agreement with the observed ones.
