新疆地震条带的定量分析

本文试图利用一个新的参数值C_B—带状集中度来定量分析地震空间分布的成带程度。根据1978年1月—1989年8月新疆拜城、乌鲁木齐、乌苏、富蕴四个地震区的地震资料,算出了四条C_B—t曲线,发现在研究的时段和区域内发生的15次Ms≥5.0级地震,其中绝大多数有C_B高值异常。

THE QUANTITATIVE ANALYSIS OF SEISMIC BELT IN XINJIANG

In this paper, we tried to use a new parameter value CB-banded concentrative strength to analyse the zonation of the space distribution of earthquakes in the region. According to the seismic data of Baichen, Urumqi, Wusu and Fuyun in Xinjiang from 1978.1 to 1989.8, we have calculated four curves of CB-t and found out that the abnormal high values of CB often occurred before the fifteen stronger earthquakes, which took place in the researching regions and times, and the CB value remained low during the normal times.
