Icelandic authorities have declared a state of emergency after a series of powerful earthquakes rocked the country’s southwestern Reykjanes peninsula, signalling the increased likelihood of a volcanic eruption in the region.

“The National police chief … declares a state of emergency for civil defence due to the intense earthquake (activity) at Sundhnjukagigar, north of Grindavik,” the Department of Civil Protection and Emergency Management said in a statement.

“Earthquakes can become larger than those that have occurred and this series of events could lead to an eruption,” the administration warned.
