Abstract In order to study the present movement state of Shandong and surrounding blocks, GPS data from the Crustal Movement Observation Network of China (CMONOC) and the Continuous Observation GPS Network of Shandong Province was used and thus analyzed the baselines between GPS stations on different blocks. Using the K-L best straight line fitting and Slide Fourier method, we got the baselines changes by year cycle, and analyzed the trend of baselines crossing different blocks. In addition,we obtain the present crustal movement characteristics of Shandong and surrounding blocks, and analyzed the influence of Japanese earthquake of 9.0 on Shandong area.
Key words ：
crustal movement
Shandong province
GPS
baselines change
seismic risk
Japanese earthquake
