摘要 "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。
