Abstract: With the rapid development of China’s earthquake prevention and mitigation, earthquake science and technology innovation and earthquake information construction are changing day by day. The national seismic science and technology projects are increasing, but the development of corresponding information technology of seismic science and technology archives is lagging behind. The classification method and file number compilation method of seismic science and technology archives are still using the regulations of 25 years ago, which are out of line with the requirements of national archives management standard and the development of seismic science and technology innovation under the new situation. Therefore, how to scientifically classify and compile file numbers for seismic science and technology archives to meet the current needs of the development of earthquake prevention and disaster reduction and to provide efficient services for earthquake research is an urgent problem to be solved.
