4. 2. Regulations on Power Supply System Storage battery should set fence protection because storage battery inclines easily and current halt. Fence protection measures should be set particularly in big aquarium-like storage battery and outlet of storage battery should adopt soft connection way. Various high voltage electrical equipment with electromagnetic type, such as breaker, separation earthquake switch, current mutual inductance equipment, voltage mutual inductance equipment, Lightning arresters and brace insulator should be seamed or connected firmly by bolts with basis, in case of inclining in earthquake. Other regulations of civil structures and electric facilities.

7. Steps of Seismic Decision Ⅰ To fast determine seismic source parameters. Ⅱ To fast estimate economy losses, injured and death. The population by seismic disaster prediction method. Ⅲ to determine the levels of earthquake emergency response. Ⅳ The rescue team, specialist team to earthquake site. Further justify seismic activity trend in the future Evaluate economy losses and the numbers of death and injured Ⅴ To take other emergency actions.

8. Levels of Seismic Decision. While general destructive earthquake happened the condition of seismic decision is: 5.0≤M<6.5, there are some deaths and economy loss. While seriously destructive earthquake happened the condition of seismic decision is: 6.5≤M<7.0, there are death population more than 200~1000. While the most seriously destructive earthquake happened the condition of seismic decision is: M≥7.0, there are death population more than 1000.

22. . Major electrical power failure can be caused by disconnectivity and abnormal load flow in a power transmission network.. Disconnectivity would be occurred primarily through civil structural damage and damage of the equipment, whereas abnormal power flow could result from power imbalance, abnormal voltage, or operational power interruption.. Power supply network system is studied by load flow analysis and net linked probability analysis in the paper.. Some meaning seismic decision ideas have been gotten. 6. Discussion and conclusion
