Short summary
We present a suite of realistic 3D dynamic rupture earthquake–tsunami scenarios for the Húsavík–Flatey Fault Zone in North Iceland and compare one-way linked and fully coupled modeling workflows on two fault system geometries. We find that our dynamic rupture simulation on a less segmented strike-slip fault system causes local tsunami wave heights (crest to trough) of up to ~ 0.9 m due to the large shallow fault slip (~ 8 m), rake rotation (± 20°), and coseismic vertical displacements (± 1 m).
