新疆境内北天山西段地震活动图象的定量研究

文中应用带状集中度C_b值、信息熵H值及缺信量I_q值,定量分析了近年来新疆境内北天山西段小震活动图象的异常特征。结果表明,在这个构造较为复杂的研究区内,C_b、H、I_q值的变化均能较好的反映中、强震的短——临异常信息。

THE QUANTITATIVE ANALYSIS OF SEISMIC ACTIVITY PATTERN IN THE WESTERN PART OF NORTH TIANSHAN IN XINJIANG

In this paper ,the band concentricity ft,information entropy H and lack-information /, have been used to quantitatively analyze the seismic activity patterns in the western part of North Tianshan in Xinjiang. The results show that in the research region ,all of the Cb,H,Iq values are sensitive in short term and impending precursors before medium-strong earthquakes.
