Comparative Study on Time Domain Simulation between Short Period Velocity Records and Acceleration Records in Local Earthquakes Monitoring

The short period velocity record and acceleration record of the same station in Chengdu network is mutual simulated by the use of the time domain recursive simulation algorithm. And the results show that, the time domain and frequency domain characteristics of the simulation results are consistent with that of the original observation records, and the error is generally not more than 10 percents. The short period seismometers and strong seismometers can be replaced in a way during the small and medium local earthquakes monitoring.
