According to the Icelandic Meteorological Office the swarm began at 12 minutes past 7 in the morning, with an epicenter 2.5-3 km (1.5-1.9 mi) north-east of Fagradalsfjall mountain, which is located east of the popular tourist destination the Blue Lagoon. The epicenter of the latest quake was 2.7 km (1.7 mi) north east of Fagradalsfjall, 11.4 km (7 mi) east of the Blue Lagoon.

The epicenter of the quakes is at a significant depth, the first two powerful quake took place at a depth of 4.9 km (3 mi) and 10.4 km (6.5 mi). The third 3.9 magnitude quake was at a depth of 2.3 km (1.4 mi). 

Reykjanes is an extremely active area, with high levels of volcanic, geothermal and seismic activity. The peninsula is effectively an extension of the North Atlantic Ridge, the boundary between the North American and European tectonic plates. The quakes are most likely connected with the movement of the plates, which are drifting apart at a pace of several centimeters each year on the Reykjanes peninsula.

There are no signs of imminent volcanic activity in the area.
