摘要

保加利亚西部地区,特别是保加利亚西南部地区,由于有大量活动断层,是地 球动力学活跃的地区。利用全球导航卫星系统测量对该地区地球动力过程的观测已持续了 26 年多,涉及 38 个台站。本文介绍了该地区现代地壳运动监测的最新结果。目前测量了 26 个点,其中 10 个是新增加的。通过处理和分析 1997 年至 2023 年期间定期活动测量获得的全球导航卫星系统数据,得出了点运动地球动力网络和变形累积的结果。经过多年的定期测量,获得了更加准确可靠的点速度结果。该地区北部的速度为 1-2 毫米/年,最南部为 3-4 毫米/年。新的结果清楚地证实了这一点以及保加利亚西南部向南部的大范围移动。增加 10 个新点和扩大网络所获得的结果提供了更好、更详细的信息,可用于对该地区活 动构造进行详细的地球动力学和地质学研究。

Monitoring of recent crustal movements in the region of western Bulgaria. Results from 2023
The region of west Bulgaria and especially southwest Bulgaria is geodynamically active region due to the large number of active faults. The observation of geodynamic processes using GNSS measurements in the area has been going on for more than 26 years involving 38 stations. This article shows the latest results of the monitoring of modern crustal movements in the area. Presently, 26 points are measured, 10 of them newly added. GNSS data obtained from periodic campaign measurements between 1997 and 2023 are processed and analyzed to obtain the result of points movements geodynamic network and deformation accumulation. As a result of many years of periodic measurements, much more accurate and reliable results for point velocities are obtained. The velocity rates are between 1–2 mm/y in the north and 3–4 mm/y in the southernmost part of the area. The new results clearly confirm this as well as the extensive movement of southwestern Bulgaria to the south. The results obtained from the addition of 10 new points and the expansion of the network provide better and more detailed information and can be used for detailed geodynamic and geological research of the active tectonics in the area.
