Taking the necessity and feasibility of developing the real-time earthquake safety mapping and public dynamic query system as an example,the social requirement for the civil products of natural disaster mitigation and security information is expounded.

Active faults and seismic safety in Fujian coastal harbour construction;

The general situation of the rural residential seismic safety in Anhui is elaborated by investigation of the current situation of rural residential houses.

The analysis shows that remaining long enough deposited beach,controlling wier lead and lowering the phreatic surface of the dam are very important to ensure the earthquake safety and stability of the tailings dams and will provide practioe b.

The comprehensive promotion of seismic safety of coastal engineering in Qingdao is not only a key scientific program but also a systematic engineering construction, and is of great importance to the sustainable development of Qingdao′s economy.
