Iceland’s biggest volcano has been shaken by a series of earthquakes in the past week, possibly presaging an eruption.

The 6,590-foot Bardarbunga volcano, buried underneath the Vatnajökull glacier, has been hit with four quakes. According to Pall Einarsson, a geophysicist at the University of Iceland, this shows that pressure in the volcanoes magma chamber is increasing.
