Abstract
In order provide basic data for strong ground motion distribution of the recent damaging earthquakes, the occurrence areas of destructive ground motion are collected from isoseismal maps of the earthquakes and their characteristics are examined. The results show that the areas of seismic intensity more than 6 lower almost agree with the previous earthquake data while the areas of seismic intensity 7 are smaller. We also confirmed that the distance from the earthquake fault and the local ground condition largely affect the occurrence of the destructive ground motion.
