DataSheet1_Distribution of Strongest Aftershock Magnitudes in Mining-Induced Seismicity.PDF

The paper considers the distribution of magnitudes of the strongest aftershocks–depending on the time after the main shock–that occur during the extraction of minerals in tectonically loaded rock massifs. The study is based on the data of long-term seismological observations at the apatite-nepheline deposits of the Khibiny Massif located in the Kola Peninsula. The article demonstrates that the distribution of the difference between the magnitudes of the strongest aftershock and the main shock is described by the dynamic Båth law, previously obtained by the authors during the study of the regularities of aftershock processes of tectonic earthquakes.本文探讨了构造应力加载岩体矿区采矿作业期间发生的最强余震的震级分布——该分布随主震后时长动态变化。本研究基于位于科拉半岛的希比内岩体（Khibiny Massif）磷灰石-霞石矿床的长期地震观测数据。本文证实，最强余震与主震的震级差值分布符合动态巴瑟定律（dynamic Båth law），该定律此前由作者在研究构造地震余震过程规律时推导得出。
