摘要
汾渭地震带M_s≥6级地震在时间上具有可公度性,可公度值为4.09年。中强地震序次节律存在以3为倍数的韵律特征,据此可建立该带M_s≥6级地震可公度性预测公式。对1989年大同M_s=6.1级地震检验表明,预测公式有较强的稳定性和较高的预测精度,结合节律分析可对汾渭地震带今后的中强地震活动作出一定程度的预测。
The Ms°6. 0 earthquake on Fen-Wei seismic zone is of commensurability in time series. The commensurable value is equal to 4. 09 years. The succession rhythm for moderate shocks has got the character of which can be multiplied by 3, and from this we set up a predicting model of commensurability for those Ms°6. 0 earthquakes on the zone. After checking them up ,we have found that this model gets a higher stability and precision and is valuable in moderate earthquake prediction in future , combining with the rhythm analyis.
