Four seismic zoning maps of China respectively published in 1957,1977,1990,and 2001 are inspected in this study.The isoseismals of shallow earthquakes of M≥ 5 occurring in the mainland of China after the maps were published are overlaid on the maps by means of Geographic Information System (GIS).The total areas with observed intensity of at least 1° larger than the corresponding intensity on the maps are summed.The percentages of areas with positive intensity difference against the entire mainland of China are calculated by the GIS function of special manipulation and analysis.The reliability of each map is tested according to its hazard definition.A key point for improving zoning methods is suggested by recognizing regions with the potential for large earthquakes ofM ≥ 7 on the basis of statistics of deaths,injuries,and losses by earthquakes during the four time periods.
