摘要
采用多种数学方法,对龙岩地震台SQ-70型水平摆倾斜仪1989—1998年的观测数据进行处理,并利用EIS2000软件进行绘图分析。得出:龙岩地区两次4.5级以上地震前,龙岩地震台地倾斜观测值均有异常变化。
The observations of the horizonal penbulum tiltmeter at Longyqn seismostation from 1989 to 1998 are arranged systematically,and then,the data are processed by using a variety of mathematical methods,and their result curves are drawn out and analyzed with software EIS2000.It can be seen that there were anomalous variation of the ground tilt value at the Longyan station before the two above %M%s4.5 earthquakes in Longyan area.
