摘要
从信息量的角度出发,研究定量描述地震活动时空分布异常图象的方法,并定义缺信量I_q值来定量分析地震活动在时间轴上或空间上分布图象的异常程度。文中还根据1978～1990年新疆天山部分地区的地震资料,计算出了4条I_q——t曲线,发现在研究的时段和区域内发生的10多次M_s≥5.0级地震,绝大多数有I_q低值异常。
In this paper, a method of quantitatively scanning the temporal spatial distribution of small earthquakes has been studied from the information amount,and the abnormal degree of those patterns has been quantitatively analyzed by the information deficiency value Iq. Based on the seismic data of Tianshan in Xinjiang from Jan. 1987 to Nov. 1990, the Iq-t seasonal curves have been calculated and the abnormal low values have been almost found during the above mentioned period before the strong earthquakes (Ms=5. 0) in the research regions.
