Journal: Earthquakes in Northern Eurasia
Year: 2025

The results of calculation and analysis of the amplitude and energy spectra of P- and S-waves of earthquakes in the Crimean-Black Sea region for 2021 are presented. For 12 earthquakes in the range of energy classes Кп=7.0–10.2, the dynamic parameters of the sources (М0, r0, Δσ, ε, ησ, Δσr, ū, EU and Mw) were reconstructed from the amplitude spectra using Brune’s theoretical dislocation model (ω –2 ). The average values of the dynamic parameters of earthquake sources in 2021 are in most cases est
