| 摘 要： | In this paper we discuss the differences and relationship between ＂great earthquakes＂, rare ground motion, and very rare ground motion. Taking the Beichuan-Yingxiu potential seismic source zone in Longmenshan seismic belt as an example, we revealed the relationship between the effects of ＂great earthquakes＂ and rare ground and very rare ground motion. After pointing out scientific and technical problems in the current seismic fortification system, we suggest that very rare ground motion should be considered if we want to deduce the potential hazard of great earthquakes in the future.
