Аnnotation: In this paper, we continue studying parameters of propagation of seismic waves in the Northern Caucasus and estimate the quality factor ( Q -factor) of the crust and the upper mantle in the vicinity of Makhachkala, which is compared with the previously estimated quality factors in the vicinities of Sochi, Anapa, and Kislovodsk. Based on the records of regional (with epicentral distances < 300 km) earthquakes ( M
