Time-space order of severe earthquake disaster chain and its prediction;

Characteristics of seismic disaster in rural area and relative disaster reduction countermeasures in China;

Main factors influencing seismic disasters risk and a fuzzy algorithm for the risk evaluation index;

Gansu Province is one of region with the most serious seismic disasters.

) In order to exhibit some overall perspective of the approaches, this paper reviews the development history of earthquake damage information acquisition methods based on remote sensing and summarizes earthquake damage identification techniques in every development stage of remote sensing.

In this paper, the status quo and problems of earthquake damage evaluation are analyzed and the feasibility of application of GIS technique in earthquake damage evaluation is discussed.

The relation between earthquake intensity and the average loss ratio of rural houses in earthquake damage is given.

The research result indicates that the seismic hazards show the character of frequent occurrence,various types,wide-ranging distribution and heavy damage.

The main topic in earthquake dynamics is to deal with rupture processes, faulting mechanism, source radiation, and propagation of the radiated seismic waves and ground motions, on which seismic hazard assessment is based.

It is thought, from the analysis on the global seismic trend and recent seismic activity in and around the continent of China, that the fifth high seismic activity period in the continent of China is getting over, but it does not mean the level of seismic hazard will come down.
