Considering different spatial and temporal ranges for the same earthquake，we investigate the objectivity and generality of the phenomenon of accelerating strain release before stmng earthquakes. A systematic analysis of all the earthquakes which occurred in China with Ms≥7.0 from 1990 to 2003 is conducted. It is found that the real seismic activity seems much more complex than the simple pattern as described by the accelerating strain release model.Therefore，the potentials of application of accelerating strain release model to the estimation of seismic hazard are in need of future investigation.
