Abstract

The Gorlovsky coal deposit began to be intensively developed in the last decade, and, as a result, technogenic earthquakes started to occur in the area of its quarries. The Kolyvan earthquake with M = 4.3, which occurred on January 9, 2019, was the largest of them and had a tangible impact on settlements including the city of Novosibirsk. This earthquake is the strongest in the area for more than a hundred years, being second to the 1882 Berdsk earthquake. Based on the analysis of seismicity, it is shown that the seismic hazards for Novosibirsk from natural and technogenic seismicity are comparable. The only differences are that zones of natural and technogenic seismicity are spatially remote from each other and catastrophic natural earthquakes will occur less frequently than technogenic ones.

2019年1月9日科利文地震，ML = 4.3，戈洛夫斯基煤盆地的诱发地震特征

摘要

在过去的十年中，戈洛夫斯基的煤炭矿床开始大量开发，结果，在其采石场附近发生了技术性地震。2019年1月9日发生的M = 4.3的科利文地震是其中最大的一次，对包括新西伯利亚市在内的定居点产生了明显影响。这次地震是该地区一百多年来最强烈的地震，仅次于1882年的别尔德斯克地震。通过对地震活动性的分析，表明新西伯利亚的自然和技术地震活动对地震的危害具有可比性。唯一的区别是自然地震区和技术地震区在空间上彼此相距遥远，而灾难性自然地震的发生频率要低于技术地震区。
