摘要

基于GNSS水平运动数据，描述了西北高加索和中高加索地区的当代形变场。结果表明，形变速度足以激活该地区的大型断层，随后发生矩震级达7.0级的地震事件。然而，造山带的抬升速度高达12mm /年，并不能仅仅用外部水平应力的作用来解释其变化多端的深部破碎起伏。这些过程在很大程度上取决于内部的均衡力。

Analysis of Contemporary Deformations of the North-Western Caucasus and Ciscaucasia Based on GNSS Data

The field of the contemporary deformation of the North-Western Caucasus and Ciscaucasia is described based on GNSS horizontal movement data. It is shown that the deformation velocity is sufficient for the activation of large-scale faults of the region to be followed by seismic events with a moment magnitude of up to 7.0. Yet, the orogenic uplift at a rate of up to 12 mm/yr and the development of its varied, deep-broken relief cannot be explained only by the effect of external horizontal stresses. These processes are conditioned, to a great extent, on internal isostatic forces.
