An earthquake measuring 2.6 occurred at 1:20 PM about 1.4 kilometers West-Southwest of Grindavík on the Reykjanes peninsula in Southwest Iceland on Sunday, RÚV reports. It was measured at a depth of 6 kilometers. A local from the area reported that he was able to feel the earthquake in town, but that it wasn’t strong enough to knock things off his bookshelves.
Per the Icelandic Met Office, at the end of April, “[o]ver 520 earthquakes were detected by the IMO's SIL seismic network, considerably more than in the previous week.” The largest of these was measured at 3.8 in Bárðarbunga, the stratovolcano that last erupted between August 2014 and February 2015, on April 29. This isn’t in and of itself any cause for great concern: due to its location on the Mid-Atlantic Ridge, Iceland regularly experiences earthquakes and earthquake swarms, often experiencing as many as 500 small magnitude earthquakes in a week.
