应用波速比预报地震的某些问题讨论

THE DISCUSSION ON THE PROBLEMS OF EARTHQUAKE PREDICTION BY VELOCITY RATIO

本文讨论了地震波速变比异常在地震预报应用中的一些问题。如多台求波速比值方法的误差因子、是否存在正异常的问题、关于异常时间的判别指标以及异常与空区的关系等。为了说明问题,列举了众多天然地震的震例以及一项人工爆破的试验结果。这些讨论的问题对于应用波速比异常预报地震的实践是有意义的。

Some problems have been discussed, such as the error factors, the positive anomaly of velocity ratio, the anomalous time indices and the relation between anomaly and seismic gap. Many actual examples are presented and a result of an artificial explosion has also beem introduced, It is significant to discuss the above problems for the earthquake prediction by anomalous velocity ratio.
