“Earthquakes can be expected to continue in the area, and the strongest of them near Grindavík. “The most likely explanation for this activity is a magma intrusion at a depth of 3-5km (1.9-3.1mi) just west of Þorbjörn. Most often such activity concludes without an eruption,” the statement closes.
According to geophysicist Páll Einarsson, if an eruption were to occur, experts would most likely be able to warn authorities hours in advance.”
