日本位于世界上最活跃的地区之一，太平洋和菲律宾海板块正在向欧亚板块俯冲，地壳的应力和应变在那里积累（图1）。这导致了许多地震、海啸和火山爆发。一年中定位的地震多达50000次，其中实际感觉到的地震有1000-2000次（图2）。有些袭击城镇，造成破坏性灾害。兵库县南部大地震（坂神淡路大地震灾害）是近50年来最严重的地震灾害，伤亡人数超过6000人。因此，预防和减轻这种现象造成的灾害的努力一直是日本最重要的国家方案之一。
Japan is situated in one of the most active areas in the world, where the Pacific and Philippine Sea Plates are subducting the Eurasian Plate and where stress and strain of the crust are accumulated (Fig. 1). This results in a lot of earthquakes, tsunamis and volcanic eruptions. As many as 50000 earthquakes are located in a year, among which 1000–2000 earthquakes are actually felt (Fig. 2). Some strike towns and cities causing destructive disasters. The Southern Hyogo Prefecture Earthquake (the Great Han-shin-Awaji Earthquake Disaster) was the worst earthquake disaster in the past 50 years with more than 6000 casualties. Therefore, efforts for prevention and mitigation of disasters caused by such phenomena have been continued as one of the most important national programs in Japan.
