| 摘 要： | 本文把地震矩和地面加速度之间的理论关系与地震烈度和该加速度之间的经验关系结合起来,导出了使用Ⅵ度等震线平均半径估算我国历史大地震矩震级的公式。 我们使用这一公式给出了53个大地震的矩震级,并对其它震源参数作了计算和讨论。从本文的结果来看,板内地震的矩震级不大于9.0。

| Abstract: | Combining a theoretical relationship between the seismic moment and the acceleration of an earthquake with an empirical relationship between the intensity and accelaration, this paper derived a formula to estimate the moment magnitude Mw of large historical earthquakes in China by using the average radius of the isoseismal line with intensity VI.This formula was applied to 53 events. Other source parameters were calculated and discussed. It appears that there are no intraplate earthquakes with Mw larger than 9.0 based on our results. |
