     Choosing the East China offshore areas as the study area （25～41°N,117～126°E）, we divided the seismotectonic unit based on the regional seismotectonic setting and earthquake activity level etc. , and calculated the earthquake occurrence rate of each grid point by using seismic activity parameter evaluation method of circu- lar-Gaussian smoothing model based on the input earthquake catalog and fault-rupture-oriented elliptical smoot- hing model. On the basis on the grid source, we obtained the division maps of ground acceleration peak with ex- ceedance probability of 10% in 50 years by seismic hazard probability evaluation method.
