The epicenter of the swarm is 230 km (143 miles) north of the coast of North Iceland, on Kolbeinseyjarhryggur ridge, a part of the Mid Atlantic Ridge extending to the north from Iceland into the Arctic. The part of the ridge is named after Kolbeinsey Island, a small volcanic island which has been eroded by the fierce waves of the Arctic Ocean.

A powerful earthquake swarm took place just north of Kolbeinsey one month ago.
