Scientists in Iceland say they are examining several 'cauldrons' found near Bardarbunga volcano, which could potentially be a sign of an eruption. The cauldrons, depressions in the volcano's surface, each between 10-15m (49 ft) deep and 1km (0.6 miles) wide, were seen during a flight on Wednesday. via Pocket http://ift.tt/1mWDAsF
