SPECTRAL and SOURCE PARAMETERS of NORTH CAUCASUS EARTHQUAKES in 2020
Journal: Earthquakes in Northern Eurasia
Year: 2024

The spectral parameters of the sources of 38 earthquakes in the North Caucasus were determined from the displacement spectra of S-waves for the period 2020. The calculations used events with an energy classes KR=9.3–12.9 and waveforms from stations with epicentral distances 50–250 km. The values of local magnitudes ML were calculated using a new calibration curve. The calculation of source spectra was carried out in the SEISAN program based on the frequency-dependent quality factor Q(f). The fol
