The seismic zoning map of China (1999) is a new generation of the hazard map of the country. The project was start in 1996. Hundred scientists were involved in this project. The new data and results achieved in about ten years enrich the database of the seismic zoning. The parameters of standard response spectrum of acceleration, A and T _g, were used as the zoning parameters. The probabilistic approach was adopted in this project. The seismicity parameters such as annual occurrence rates and b value are determined in a large region called seismic provinces. The annual occurrence rates of the potential source are evaluated from relative spatial distribution of the earthquakes with different magnitude. The logic tree is used to treat the uncertainty in the delineation of the potential. Three groups of scientists with different background provided their own potential sources of the country. The attenuation of the parameters was regressed from the data of the western United States. The curves were modified through the comparison of the attenuation of intensity in both countries. The country was zoned by A and T_g. There are frequent interaction with the users and local people. We emphasis the engineering application of the zoning map.
