Eurasian Plate
The quake reportedly occurred within the subducting Arabian Plate below the overriding Eurasian Plate. The Strait of Hormuz separates two forms of plate collision. To the northwest, continental crust portions of the Arabian and Eurasian Plates are colliding, resulting in compressive faulting. To the southeast, dense oceanic crust of the Arabian Plate is subducting underneath the Eurasian Plate at the Makran Trench.
