【摘要】 结合甘孜地区的地震构造,对甘孜县境内及县城附近55 km范围内发生的ML≥3.0级以上地震与周围地区的中强地震活动分析,发现甘孜附近3.0级以上地震与附近地区的中强地震的发生具有一定对应关系,提出了2个预测指标,预测时间为半年的通过了置信水平为97.5%的R值检验,分析认为甘孜地区的地震活动是鲜水河地震带强震活动及附近中强地震活动的指示窗口。更多还原

【Abstract】 According to the geological structure around Ganzi area,we analyze the activities of small earthquakes(M>=3.0) and the medium-strong earthquakes within the range of 55 kilometer and find a relationship between small earthquakes and moderate-strong earthquakes.Then we put forward 2 predictive indexes based on the seismic activity around Ganzi area.These indexes are useful for the earthquake prediction for this region.更多还原
