Simulation of co-seismic secondary fracture displacements for different earthquake rupture scenarios at the proposed nuclear waste repository site in Forsmark

•We simulate secondary fracture displacements induced by high stress drop earthquakes.•We vary hypocentre location, rupture velocity and amount of strain energy release.•In the near field, close to fault edges, the static stress effects dominate.•No displacement in the proposed repository area exceeds 40 mm (150 m radius fracture).•Large stress drops suggest that the fracture displacements are upper bound estimates.
