Formation of the earthquake preparation area: development of S.V. Goldin’s concepts
https://doi.org/10.18303/2619-1563-2026-1-48
Abstract
New data on the formation of an earthquake preparation zone, based on the development of S.V. Goldin's concepts, are presented. Evidence is obtained of the repacking of the block system on the eve of a strong earthquake, the formation of a deformation shadow zone in the area of the future earthquake, and the nature of medium-term seismic quiescences and short-term silence pauses is discussed.
Supporting agencies: the study was carried out within the framework of the state assignment FWZZ-2026-0051.
