Source mechanism and tectonic setting of 29.09.2017 earthquake near Stebnyk

Purpose. The paper’s purpose consists in determining the source mechanism of 29.09.2017 earthquake near Stebnyk (21h46m8,4s, = 49,34˚, λ = 23,49˚, h = 1,9 км, MD = 2,9) using two methods – from polarities of first P-wave arrivals and by inversion of wave forms registered at a limited number of stations. Methodology. Seismic waves in the inhomogeneous medium represented by horizontally layered elastic structure are calculated using the matrix method.
