The place where the earthquake occurred is a seismically active area, where 3 plates meet, the North American plate to the Northeast, the Cocos plate and the Rivera plate to the South. Both the Cocos and Rivera plates are slowly sinking below the North American plate by 2 centimeters (0,79 inches) per year, relative to the rapid movement of the Cocos Plate with that of North America which moves 4 centimeters (1.8 in) per year.

## Earthquake 
The earthquake occurred due to thrust fault, between the Cocos plate and North America plate. This earthquake is not related to that of 1985, 1995 and 2003. According to the United States Geological Survey, earthquakes of this size typically rupture in an area measuring 90 km (56 mi) x 40 km (25 mi). Most of the co-seismic slip occurred directly below ground rather than offshore with a maximum displacement of 1.2 m (3 ft 11 in). 

The earthquake coincides with the 37th anniversary of the 1985 earthquake that killed 10,000 people and the 5th anniversary of the 2017 earthquake, an hour before the national drill of 19S had occurred in case of earthquakes.
