Around 290 earthquakes were detected last week by the national seismic network of the Icelandic Meteorological Office, slight increase in numbered events from the week before. The largest earthquakes of the week M2.9 both were suboceanic. First one, 45km WSW of Reykjanes peninsula and the latter 170km north of the country. Rather low activity in BÃ¡rÃ°arbunga volcano with only 7 earthquakes detected this week. The largest earthquake there measured at M1.6 in the northeastern caldera rim on February 13th. More seismic activity in MÃ½rdalsjÃ¶kull glacier with 70 detected events, majority of which were small. Three earthquakes measured above M2.0 counting the largest event M2.5 on the 19th. More

Mass balance measurements carried out by the Institute of Earth Sciences at the University of Iceland and the Icelandic Meteorological Office have shown that glaciers in Iceland have retreated and thinned steadily since 1995. The volume of the glaciers has been reduced by approximately 10 km³ per year on average. The mass loss of the glaciers causes perturbations in the Earth's gravity field near Iceland that are detected by sensitive instruments on board of German/American GRACE satellites.Read more
