Abstract Aiming at the uncertainty of earthquake discrimination by using anomaly of fault deformation, 3 strong earthquakes in the northeast margin of QinghaiTibet block as typical examples were analyzed. In addition, the abnormal characteristics (modality、time series、spatial distributing) of fault deformation before the earthquake, the seismic activity of correlative outer tectonic region were analyzed.From these analyses the following conclusions are drawn. If the anomaly of fault deformation satisfies the criterion of abnormal characteristics before earthquake and the seismic activity of correlative outer tectonic region is strong, the possibility of an earthquake is big; otherwise little possibility of an earthquake.
Key words ：
anomaly of fault deformation
northeastern margin of QinghaiTibet block
earthquake
no earthquake
discrimination
