USGS Tectonic Summary “The June 22, 2017 M 6.8 earthquake offshore of Guatemala occurred as the result of shallow thrust faulting on or near the subduction zone interface in the region. At the location of this earthquake, the Cocos plate converges with the Caribbean plate at a rate of 69 mm/yr towards the northeast, and subducts beneath Central America at the Middle America Trench, 110 km to the southwest of this earthquake. The June 22nd event is located near to the triple junction between the Cocos, Caribbean, and North America tectonic plates; just to the northwest of this earthquake, the Cocos plate subducts beneath the North America plate at the slightly faster rate of 79 mm/yr, accommodating left-lateral strike-slip motion between the Caribbean and North America plates near the surface in south-central Guatemala. The location, depth, and focal mechanism solution of the June 22nd earthquake are all consistent with the event occurring on the subduction zone interface.”
