本文用苏03井记录到的全球大地震的井水地震图上的脉冲振幅A与相应持续时间T求得Msτ震级的公式: Msτ=1.02LogT+0.756 LogA+5.73 结果表明,所求得的震级Msτ值与地震目录的Ms震级标准差小于0.20。此方法简便,易于计算,也许是求全球大地震震级的一种较好途径。
This paper uses the pulse amplitude A and the corresponding duration T of the well water seismogram of the global earthquake recorded by Well Su in the well to obtain the formula of Msτ magnitude: Msτ = 1.02LogT + 0.756 LogA + 5.73 The results show that the obtained magnitude The Ms magnitude and Ms magnitude standard deviation of the earthquake catalog are less than 0.20. This method is simple and easy to calculate and may be a better way to find the magnitude of the global earthquake.
