A series of large earthquakes hit Bárðarbunga, one of Icelands’ top three volcanoes in the running for the next eruption, as four large earthquakes occurred in it’s volcanic system last night. The earthquakes in Bárðarbunga volcano last night were measured as being the largest occuring there since the volcanos’ 2014-2015 eruption. The first earthquake, measured up as a 3.9 on the Richter scale, occured at 23:02 last night. It was then closely followed by a 3.2 earthquake at 23:03, with the third quake, measured as a 4.7, hitting the volcano at 23:26. The fourth earthquake of a magnitude of 4.7 on Richter occured at 12:16, or sixteen minutes past midnight.
Located under the northern part of the Vatnajökull glacier, Europe’s largest glacier in South Iceland, with a volcanic system approximately 200 km (120 miles) long, Bárðarbunga is the largest and most powerful volcano in Iceland. The 2014-2015 Holuhraun eruption in the Vatnajökull volcanic system on the edge of the glacier is the largest volcanic erpution in Iceland since 1783, and earthquakes of the magnitude of 4.7 on the Richter scale are the largest earthquakes to have occured in the Bárðarbunga caldera since the 2014 eruption. The Holuhraun eruption, which began on August 31st 2014, lasted until February 28, 2015, the eruption producing a huge lava field of more than 85 km2 (33 square miles) up in the highlands in the middle of Iceland.
