合肥遥测台网限幅时间震级公式

The Clipping time Magnitude Formula for Hefei Telemetric Seismic Network

为了满足遥测地震台网地震速报的需要，本文利用地震限幅时间拟合给出了合肥遥测台网确定限幅地震震级的经验公式，给出了精度分析结果，认为在近震范围内利用地震限幅时间确定遥测台网内外多台限幅情况下的地震震级，是一种可行的方法，与地震持续时间方法比较，具有速度快。

In order to meet the needs of rapid earthquake determination for telemetric seismic network, an empirical formula for calculating the magnitude of clipped earthquake is established by using the method of the clipping time fit and the precision of the magnitude is given The results show that is a feasible way to calculate the magnitude of multistation clipped earthquake inside or outside network with clipping time information in the area of near earthquake Comparing with the duration magnitude calculation,this method has the adventages of more rapid speed and higher precision
