摘要
通过对2013年数字水平摆倾斜仪观测资料的分析研究,发现不同地震台站的水平摆倾斜仪对不同地区的地震,可记录到相同的形变特征,而对同一地区的地震形变异常记录形态各异。以巴基斯坦7.8级、安德裂亚诺夫群岛7.0级地震为例,总结在这两次地震前后的异常特征,结果表明,不同台站的水平摆倾斜仪在这两次地震前记录到了相同的异常特征。
By analyzing the observation data of digital horizontal pendulum tiltmeter in 2013in Shanxi,we find that deformation features of earthquakes in different regions recorded in horizontal pendulum tiltmeters may be the same in different stations,whereas the features of earthquakes recorded in the same region are different.Taking the Pakistan 7.8and Andrea Ivanov Islands 7.0Earthquake as examples,the anomalies recorded in horizontal pendulum tiltmeter in different stations are the same before both earthquakes.
