摘要
传统的地震分析通常使用微震仪记录,利用云南测震台网现有的国家台强震仪记录,仿真成速度记录后测定汶川地震主震的震级,从而解决了因微震仪记录限幅而不能及时、准确测算强震震级的问题,该方法可应用到今后的速报工作。
Traditional seismic analysis normally makes use of microseismograph records.In this paper,we simulate the strong-motion seismograph records of the Yunnan seismic network to velocity records,and use these records to determine the magnitude of the Wenchuan earthquake.The method solves the problem that accurate magnitude can not be obtained because the earthquake is so strong that the waveform recorded by microseismograph is usually clipped.This method can be applied to the quick report of strong earthquake in the future.
