华北地区地震的时间分布特征及其意义
THE TIME DISTRIBUTION CHARACTERISTIC OF EARTHQUAKES IN NORTH CHINA AREA AND ITS SIGNIFICANCE
-
摘要: 本文研究了华北地区地震的时间分布特征,结果发现华北地区地震的时间间隔与其出现频次之间存在一定的规律分布。例如:大华北地区地震有: Ms≥5.0时: 1gN△T=2.33-0.39·|△T|Ms≥6.0时: 1gN△T=1.84-0.41·|△T|本文还讨论了利用上述经验式进行地震背景性预报问题。Abstract: In this paper, the time distribution characteristic of earthquakes in North China area is studied. As a consequence, it is found that there is a certain regular distribution between time interval of earthquakes in North China area and their occurrence rates. For example, for the earthq uakes in large North China area, at Ms≥5.0 1gN△T=2.33-0.39·|△T|at Ms≥6.0 gN△T=1.84-0.41·|△T|This paper also discusses the problem of predicting seismic risk by above mentioned empiric formulas.
