The alert warning for the area surrounding Iceland's Bardarbunga volcano was kept at orange on Tuesday, indicating that it is showing increased unrest with greater potential for an eruption. Since August 16, a series of earthquakes in the area have created breaks in the Vatnajokull glacier, which is northeast of the volcano. The tremors have created cracks in the glacier, allowing streams of lava to pour through. In the past 72 hours, the volcanic activity has increased dramatically, with the lava now covering an area of more than four square kilometres.
