A comprehensive method for estimating and comparing the damage potential of strong ground motion;

The research of physical measure of seismic intensity is a history and basic subject and the study of damage potential of earthquake ground motion has been worked on for more than one hundred years.

Study on the damage potential to masonry structures of earthquake ground motions;

Latent destruction of ecological environment refers to the possible de-struction under some conditions.

The simple talk about the compositive measures to reduce the earthquake destruction for building;

Based on investigation on spot and analysis of earthquake destruction,some countermeasures were suggested in the paper.
