[4] No tsunami was generated since the earthquake was an almost pure strike-slip on a near vertical plane, producing little upward movement of the sea floor that would cause a large displacement of water.

[5] The earthquake occurred at a depth of around 10 kilometres (6.2 mi) on a transform fault zone known as the Swan Islands Transform Fault in the Cayman Trough, where it forms part of the boundary between the North American plate and the Caribbean plate.

[6] According to a finite fault model created by the U.S. Geological Survey, the earthquake generated a maximum slip of 24 meters in a compact rupture zone.

Three sub-events were discovered during the rupture process, the third of which, occurred at a velocity exceeding that of the shear wave.

Propagating at 5 km/s, faster than the shear wave velocity of 4 km/s, the event is classified as a supershear earthquake.
