The propagation velocity of seismic activity migrating along the directions of the geodynamic forces prevailing in the northeastern Baikal rift system, Russia

The recent tectonic stress field in the northeastern Baikal rift system (BRS) corresponds to crustal deformation field. stress-strain state of Earth’s crust determines fault network geometry and spatiotemporal structure epicentral characterized by many earthquake swarms migrations study area. In order seismic process dynamics different directions deformation, analysis time series has been made over 1964–2015 instrumental period. To determine relationship between features data were projected along horizontal tensor axes σ3 σ2, consistent with major a strike rifting structures, general azimuth active groups. NE-SW direction intermediate main faulted arears exhibits slow up 60 km long, propagating modal velocity about 30 kilometers per year. NW-SE principal axes, orthogonal areas, is shorter migration sequences less duration, higher than registered NE-SW. difference mutually can be attributed configuration differences process.
