Investigating Strike‐Slip Faulting Parallel to the Icelandic Plate Boundary Using Boundary Element Models

Abstract Most faults in Iceland strike roughly parallel to the divergent plate boundary, a part of North American‐Eurasian which would be expected lead primarily normal faulting. However, several studies have observed significant component rift‐parallel strike‐slip faulting Iceland. To investigate these fault kinematics, we use boundary element method model slip and crustal stress patterns Icelandic tectonic system, including spherical hotspot uniaxial that represents rifting. On network faults, estimate required relieve traction imposed by inflation remote rifting compare results with seismicity, geodetic data. We note good fit between model‐predicted deformation metrics, both indicating components consistency recent data longer‐term records geologic slip.

This work provides new insight into physical mechanisms driving styles within away from current active implying portion is likely caused combined effects rifting, impacts, mechanical interactions across network.
