摘要
对陕西6个数字化台站18套仪器近5年资料的分析结果显示:频繁的扰动具有很高的映震能力,每次扰动在400 km内有4级以上或500 km内5级以上的地震发生;汉中台垂直摆,乾县、西安水管仪和宁陕垂直摆对2008年汶川地震的余震有较好的响应;乾县台垂直摆对河津4.8级地震的响应明显。
Through analyzing deformation data in Shanxi province,perturbations frequently appeared before M≥4 earthquake in range of 400 km or M≥5 earthquake in range of 500 km.It is shown in two aspects： 1）response of vertical pendulum in Hanzhong seismostation,water tube tiltmeter at Qianxian station and Xi＇an station,vertical pendulum at Ningshan station to large aftershocks of Wenchuan Ms8.0 earthquake,2）response of vertical pendulum at Qianxian station to Hejing Ms4.8 earthquake.
