Results show that viscoelastic post-seismic relaxations caused by the 1939 Ms 7.9 Erzincan earthquake is still strong and influencing the seismic activity in the region. Post-seismic effects have increased the stress on the Yedisu segment as much as 5.3 bars, whereas supressed stress on the Kahramanmaras-Malatya segment. In general, increases in stress due to viscous-elastic effects are comparable, or in certain cases even larger than the increases in stress caused by co-seismic deformations. This indicates that the additional stress changes derived from viscoelastic deformations could be significant and should be taken into consideration when assessing seismic hazard along the active seismic zones. Two regions are identified as having high positive Coulomb stress changes therefore high seismic hazard; a segment close to Bingol Province in the East Anatolian Fault Zone and the Yedisu segment of the North Anatolian Fault Zone.eninfo:eu-repo/semantics/closedAccessEast Anatolian FaultNorth Anatolian FaultCoulomb stress changeTime-dependent seismic hazardHector-Mine-EarthquakeMojave-DesertDeformationNorthAccumulationEvolutionGpsArticle10.1016/j.jog.2019.03.0011262331Q3WOS:0004662567000032-s2.0-85062804408Q1
