南加州开展地震预报的准备短期预报是实用地震预报台网的主要目标。然而,要对可能是一次地震前兆的短临异常作出有效的判断,需要有长期基础资料、对某地区的构造格架的了解以及对作为预报目标的具体地震作出长期评定。由于认识到这种情况,美国从科学的角度普遍倾向于这样一项地震预报的战略,即通过对特定地区地震重复间隔的确定,逐步使长期地震灾害的评定工作过渡到长期地震预报,从而最终在最危险的地区进行详细的区域性监测,以作出中长和短临地
Southern California Preparation for Earthquake Prediction Short-term prediction is the main objective of a practical earthquake prediction network. However, to make an efficient judgment of the short-term anomalies that may be a precursor to the earthquake, long-term basic information is needed to understand long-term structural tectonics in a region and make long-term assessments of specific earthquakes that are the targets of prediction. In recognition of this situation, the United States generally prefers a science-based strategy for earthquake prediction by gradually transitioning the assessment of long-term earthquake disasters to long-term earthquake prediction by identifying the seismic repeat intervals in a particular area, so as to ultimately Conduct detailed regional monitoring in the most dangerous areas to make medium and short cuts
