Abstract 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 Ms4.5 earthquakes in Longyan area.
