Seismotectonic Activation of Modern Structures of the Siberian Craton

Dynamics of the Zones of Strong Earthquake Epicenters in the Arctic–Asian Seismic Belt

“…Due to thrusting, the eastern wing of the anticline is overlain with the Vend-Cambrian deformed beds of the East Sette-Daban tectonic zone. The E-NE orientated compression is evidenced by two fault planes reconstructed from the seismological data for the Sette-Daban earthquake, the NE plane (right-lateral strike-slip), and the NW plane (left-lateral strike-slip) [27,32]. In general, the identified seismotectonic deformation parameters reflect the trends in the distribution of crustal stress fields reconstructed from the structural data.…”

“…The principal compressional axis is subhorizontal (dip from 3 • to 44 • ) and acts across the strike of the structural elements in this zone ( Figure 6). The extension stress axis is often coincident with the fault strike and oriented either horizontally or subvertically (dip from [27,32]). 1-7-ages of deposits: 1-Cretaceous, 2-Jurassic, 3-Carboniferous-Permian, 4-Ordovician-Silurian-Devonian, 5-Vendian-Cambrian, 6-Middle-Upper Riphean, 7-Lower Riphean; 8-10-kinematics of active faults: 8-thrust; 9-strike-slip; 10 -normal fault; 11-syncline axis; 12-anticline axis; 13-Kyllakh earthquake epicenter; 14-focal mechanism, dates and magnitudes of earthquakes (lower hemisphere; the principal stress axes of compression and extension are marked by black and white dots, respectively).…”

Seismotectonics of the northern sector of the Verkhoyansk fold system (north-east of the Russian Arctic)

“…ПРИРОДНЫЕ РЕСУРСЫ АРКТИКИ И СУБАРКТИКИ, 2020, Т. 25, № 2 data [28]. In the western segment, positive velocities of recent vertical tectonic movements amount to 2-4 mm/year and; further to the east, velocities decrease to weakly negative values.…”

Geodynamic features of the seismotectonic structures in the central part of the Chersky Zone (North-East of Russia)

“…Локализация Арктико-Азиатского сейсмического пояса (ААСП) в Арктической зоне и на северо-востоке Азиатского континента [1,2,3,5]. В прямоугольнике показана территория исследований, представляющая сейсмотектоническую зону Черского [5,6,8]. Fig.1.…”

“…Localization of the Arctic-Asian seismic belt (AASB) in the Arctic zone and the northeast Asian continent [1,2,3,5]. The rectangle shows the research area representing the Chersky seismotectonic zone [5,6,8]. обусловленном различным типом напряженного состояния земной коры со сменой тектонических режимов на отдельных участках границы Евразийской и Североамериканской литосферных плит, и зависит от условий их взаимодействия [8].…”
