Abstract

For the 19 strongest earthquakes of Russia and the world the dynamic parameters: seismic moments, lengths of ruptures, stress drops, the values of motion in the source are brought. The spectra of Р-wave were calculated on records of IRIS-IDA digital equipment at stations Obninsk-OBN, Talay-TLY, Kislovodsk-KIV in the range of epitsentralny distances of =25–82°. On the basis of the values of seismic moment Мo received on digital records at stations Obninsk-OBN, Talay-TLY, Kislovodsk-KIV, the momentny magnitude Mw (Kana-mori) are presented.
