Геофізичні аспекти сучасних горизонтальних рухів у центральній частині Закарпатського внутрішнього прогину

The work studies the spatial-temporal distribution of seismicity in the Carpathian region in 2023 and analyzes the results of research and scientific achievements in the study of geophysical processes in seismic-generating regions. The urgency of the research is due to the fact that recently, certain features of seismic activity in the seismic-generating region have been noted, and the probability estimates of strong, noticeable earthquakes have increased. The observations of modern horizontal crustal movements in the Oash deep fault zone for the studied period have been analyzed. The relationship between the modern crustal movements and the spatial-temporal distribution of seismicity in the Carpathian region (particularly the Transcarpathian Inner Trough and the Vrancea zone (Romania)) has been studied. The existence of sign-changing processes in horizontal crustal movements in the Transcarpathian Inner Trough in the studied time interval has been shown. In modern horizontal crustal movements, there has not been found a sign-changing process that determines the nature of crustal movements for up to 10―12 years and is important in the formation of seismic activity in the region. The local seismicity correlates with the seismicity of a powerful seismic-generating region, the Vrancea zone: seismicity increases in both regions starting from May―June 2023. The seismicity of the region is associated with the processes of local compression of rocks measured in the tunnel of the deformometric observation station «Korolevе» of the Department of Seismicity of the Carpathian Region (S.I. Subbotin Institute of Geophysics of the NAS of Ukraine).
