| 摘 要： | 基于近震震级公式,得出景洪电站水库诱发地震监测台网理论监测能力在坝区为M_L 0.5,在坝区周边,理论监测能力为M_L 0.7。基于G-R震级频度关系及Wiemer Wyss最小完整性震级估计方法求取景洪电站水库诱发地震监测台网实际监测能力,结果证明,其实际监测能力能够满足理论监测能力的要求。在0.5的理论监测区范围内,最小完整性震级为M_L 0.0,而在0.7的理论监测范围内,最小完整性震级为M_L 0.4。

| Abstract: | Based on the local magnitude formula, the theoretical monitoring capabilities, in and around Jinghong Hydropower Reservoir, of seismic network are ML 0.5 and ML 0.7, respec- tively. To test the theoretical monitoring capability of seismic network of Jinghong Hydro- power Reservoir, we calculate the practical monitoring capability of seismic network of Jing- hong Hydropower Reservoir. The results show that the practical monitoring capability is consistent with the theoretical monitoring capability. In the M1 0. 5 region and M1 0. 7 of theoretical monitoring capability of seismic network, the minimum magnitudes of complete- ness are M1 0.0 and M1 0.4 respectively. |
