As densely populated and wealth concentrated regions,cities are key areas that need special seismic fortification measures. Seismic microzoning is an important technical way to finely divide urban seismic fortification units,which can help to identify the potential earthquake disaster risks and provide more scientific seismic fortification requirements for urban planning and development. From 1986 to June 2022,a total of 369 urban seismic microzoning projects have been carried out in China,in which the total seismic microzoning area is 22856.6km2,involving 61.3% of provincial capital cities or municipalities directly under the central government,33% of municipal cities,and 14.1% of county-level cities. Through literature research and by using statistical methods,in this paper we systematically reviewed the progress of urban seismic microzoning in China,and put forward some suggestions for urban seismic microzoning in the future.
