摘要

通过计算分析新疆北天山地区、南天山东段地区、南天山西段的柯坪块区及喀什—乌恰交汇区中强震前地震活动性总体状态参量Rt的变化特征,给出了各区中强震发生时间和强度基于Rt值的判定指标。Rt≤0.89可作为北天山地区1年内发生5.1～6.0级地震的指标;Rt≤0.79可作为南天山东段1年内发生5.4～6.0级地震的指标;Rt≤0.85可作为柯坪块区1.5年内发生6级地震的指标;Rt≤0.88可作为喀什—乌恰交汇区1年内发生6～7级地震的指标。
Tianshan Seismic Belt in China was divided into four areas:North Tianshan,the east of South Tianshan,Keping Block and the Kashi-Wuqia junction region.Based on the calculation and analysis result of Rt,the integrated parameter of seismic activity,before mid-strong earthquakes in the four areas,we gave the Rt-based criterion for judging the time and strength of mid-strong earthquakes in the areas.Rt≤0.89 can be as the judge index of MS5.1-6.0 earthquake occurring within one year in North Tianshan;Rt≤0.79 can be as the one of MS5.4-6.0 earthquake occurring within one year in the east of South Tianshan;Rt≤0.85 can be as that of MS6.0 earthquake occurring within 1.5 years in Keping Block;Rt≤0.88 can be as that of MS6-7 earthquake occurring within one year in the Kashi-Wuqia junction region.
