摘要
依据震中迁移、频度变化曲线、能量释放曲线、震级频度关系和时间序列的预测方法等,对陕西地区的地震活动性进行了初步分析,认为:陕西地区M_L>3.5级的地震活动存在着明显的由北向南、自东向西的迁移特点,其地震活动水平比较正常,今后5年内可能发生M_L≥4.3级地震。
Using the methods of seismic migration, variation of accumulation frequency and the relations between magnitude and frequency, thd author primarily studied the seismicity in Shaanxi seismic belt. It is obtained that the earthquakes of magnitude ML≥3. 5 in the belt have a obvious migration characteristics from north to south and from east to west. The seismicity in the belt is normal. In the next 5 years, there might have the probability of occurring the earthquakes with magnitude ML≥4. 3.
