Abstract

This paper presents the capabilities of the Franz Josef Land, Omega, and Severnaya Zemlya island-based seismic stations for seismicity monitoring in the Arctic region. We first analyze how seismicity parameters in the European sector of the Arctic region change over time; we then compare the spectral power density of microseismic noise for positioned seismic stations sites to Peterson models; and finally we analyze M_Lrepr variations and the accuracy of earthquakes location. To assess registration capabilities, we examined the monitoring results obtained for the Gakkel Ridge, which is characterized by ultra-slow spreading.

俄罗斯基于岛的地震台站的注册能力：以Gakkel山脊监测为例

摘要

本文介绍了弗朗兹·约瑟夫（Franz Josef）土地，欧米茄（Omega）和塞维尔尼亚·塞姆利亚（Severnaya Zemlya）岛型地震台站在北极地区进行地震活动监测的功能。我们首先分析北极地区欧洲部分的地震活动参数如何随时间变化；然后，我们将定位地震台站的微震噪声的频谱功率密度与Peterson模型进行比较；最后，我们分析了M _{L repr}变化和地震定位的准确性。为了评估注册能力，我们检查了Gakkel Ridge的监测结果，该监测结果的特征是超慢扩散。
