“北极”地区,即北极点位于北冰洋的中心。一直以来,北极地区影响着地球从地质时期到现在的环境变化。然而,该地区的地震活动并未得到足够的监测。因此,通过对地震现象进行长期监测并将其作为可持续参数,我们可以更深入地理解地球的构造演化和地球表层的低温层与岩石层之间的动态相互作用。本文研究了北极地区地震活动与结构的联系,特别着眼于欧亚大陆及其周围海洋,以及其与地球历史时期地区演化的关系。目标区涵盖了北极欧亚区有代表性的构造区,例如西伯利亚的广袤地区、贝加尔裂谷带、俄罗斯远东地区、北冰洋,以及格陵兰和加拿大北部。基于对地震活动特征等的讨论,本文总结了北极地球表面的地壳和上地幔的非均匀结构、大地构造史和最近的动力学特征。
“Arctic ” area, the North Pole is located in the center of the Arctic Ocean. The Arctic has long affected the Earth’s environmental changes from geology to the present. However, the seismic activity in the area has not been adequately monitored. Therefore, through the long-term monitoring of seismic phenomena as a sustainable parameter, we can gain a deeper understanding of the tectonic evolution of the Earth and the dynamic interaction between the cryosphere and the lithosphere on the Earth’s surface. This paper studies the relationship between seismic activity and structure in the Arctic, with a special focus on the oceans in and around Eurasia and its relationship with the evolution of the Earth’s history. The target area encompasses representative tectonic zones in the Eurasian Arctic, such as the vast regions of Siberia, the Baikal Rift, the Far East of Russia, the Arctic Ocean, and Greenland and northern Canada. Based on the discussion of the characteristics of seismic activity, the paper summarizes the non-uniform structure of the crust and upper mantle on the surface of the Arctic, the tectonic history and recent dynamics.
