Abstract:A method of constructing the dynamic temporal and spatial evolution image of deformation field by using records of multi permanent deformation stations is attempted. On the base of this method, water-tube tiltmeter records of 47 deformation stations in China are analyzed, and images of temporal and spatial evolution of ground tilt are constructed. As a example, the dynamic change of ground tilt before and after the Ms8. 1 earthquake west to the Kunlun Mountain pass is studied. The result shows that there are obvious changes in the day average value of water-tube tiltmeter in many stations before and after the event. The spatial distribution of EW average, NS average and NW M2 tidal factor also appear noticeable difference, but there is no noticeable change in EW M2 tidal factor. This method is expected to use in the work of earthquake prediction through constructing the temporal and spatial deformation image of every month or every week with accumulation of observition data.
