摘要
对江苏省数字地震台网观测系统与模拟台网观测系统在震级测定方面的一致性进行了探讨。定量分析了数字台网的“速度型震级”、“仿真位移型震级”与模拟台网位移震级的差异。初步结果表明 ,在测量误差允许范围内 ,数字网的“仿真位移型震级”可以替代模拟网的位移震级 ,震级测定的连续性要求基本可以保证。
The consistency of magnitude determination between networks of numeral and simulation in Jiangsu province is discussed. The difference between velocity magnitude and simulation displacement one of numeral network and displacement one of simulation network is quantitatively analyzed. Prime result shows that the simulation displacement magnitude of numeral network represent the displacement one of simulation network in the allowed measure error, and the continued requirements of magnitude determination are basically guaranteed.
