Abstract

In this study, the visibility graph analysis of seismicity triggered by Song Tranh 2 hydropower (Vietnam) is performed. The relationship between the seismic (the Gutenberg-Richter -value) and topological (the - slope) parameters of seismicity is analysed. Our findings indicate that the relationship between the Gutenberg-Richter -value and the - slope of the investigated seismicity is in agreement with that characterising the tectonic seismicity. The results obtained from analysing the reservoir-triggered seismicity of Song Tranh 2 area could contribute to better characterisation of the relationship between the seismological and topological parameters of seismicity, strengthening the universal character of the relationship between the -value and the slope.

摘要

在本研究中，对越南松川2号水电站引发地震的可视性图分析进行了研究。分析了地震活动性的地震学参数（古登堡-里希特b值）与拓扑学参数（b斜率）之间的关系。我们的研究结果表明，所研究地震活动性的古登堡-里希特b值与b斜率之间的关系与构造地震活动性的特征相符。对松川2号地区水库诱发地震活动性分析所获得的结果，有助于更好地刻画地震活动性的地震学参数与拓扑学参数之间的关系，强化b值与b斜率之间关系的普遍性。
