A 3.9 magnitude earthquake shook the Bárðarbunga caldera at around half past nine on Saturday morning. The quake is the one of the latest in a line of more than seventy that have hit the caldera from the start of last week. According to the Icelandic Meteorological Office there were around thirty earthquakes around Bárðarbunga the week before.
Three of the earthquakes a week ago were greater than three magnitude according to the National Broadcasting Service RÚV. They all occured at the northern edge of the caldera the evening of the 20th of May.
Constant seismic activity since the Holuhraun eruption
Bárðarbunga, which is located beneath Vatnajökull glacier, is one of the two largest and most powerful volcanoes in Iceland. Katla, the other, is located beneath Mýrdalsjökull glacier.
Bárðarbunga has seen constant seismic activity since the 2014-2015 Holuhraun eruption. Dozens of powerful earthquakes, larger than 3 on the Richter scale, have been detected. The seismic activity is most likely caused by the re-filling of the magma chambers of the sub-glacial Bárðarbunga, which is the heart of the most powerful volcanic system in Iceland.
