Geophysicists say seismic activity by Grimsey island in North Iceland could be activating earthquakes in a wider area, RÚV reports. An M3.6 earthquake which occurred at Öxarfjörður bay, North Iceland this morning could be connected to the seismic swarm which has shaken the residents of Grimsey over the past week.
The Öxarfjörður earthquake occurred at 7:34 this morning and was felt as far away as 90 kilometers from its source. It was followed by 20 smaller quakes.
Geophysicist Sigurlín Hjaltadóttir says it is possible a 5.2 magnitude earthquake which occurred close to Grimsey on Monday has changed the pattern of the seismic activity in the area. “The swarm by Grimsey is just the same, it’s been dying down over the past 2-3 days. It’s impossible to say what the future holds. It’s quite possible a bigger part of this belt has been activated, but we just have to wait and see,” she stated.
