【摘要】 系统总结了山西形变台网对近年来5级以上地震的映震能力,分析了形变异常特征。认为,大部分地震均发生在异常转折或异常结束时段,异常持续时间一般为半年至1 a,震中距大多为200 km~300 km,并出现明显的丛集活动。更多还原

【Abstract】 In this paper,reflecting earthquake ability of deformation network in Shanxi to earthquakes of M>5 in recent years is systematically summarized and the characteristics of deformation anomaly is also analyzed.It is concluded that the most earthquakes occur at anomaly turning time or end anomaly period of time,the anomaly duration is commonly from half a year to one year,the epicenter distance is usually 200-300 km,and obvious cluster activities appear.更多还原
