Factors to improve earthquake response are reviewed including those found by power system simulation. Factors contravening change and strategies to affect change are discussed. Many factors, such as society's increasing dependence on power, increasing population in seismically prone areas and the introduction of higher transmission voltages with attendant reduction in seismic resistance of equipment suggest that disaster may be in the offing. The extensive studies to determine if this situation exists have not been made. While serious damage to equipment and facilities has been observed in recent earthquakes, overall system response has generally been good. Thus, rigorous evaluation of power systems may demonstrate that because of their high level of redundancy only minor changes are required to yield an acceptable earthquake response. It is important that the professional community develop the methods for evaluation and improved mitigations practices so that when the opportunity presents itself implementation can be achieved.
