Abstract The leveling data crossing fault in Changjiazhuang，the NS component of tiltmeter in Yantai and gravity data in Taian before Laizhou M4.6 earthquake were analyzed.The result shows that each of the 3 kinds of observation data appeared midterm or shortterm trend abnormities.The characteristics of the abnormities is：the closer of the distance from epicenter，the earlier it occured，and the farther from epicenter，the longer it lasted for.The distance away epicenter of the farthest abnormal point reaches 276 km，and the abnormities are connected to the geological structure.
