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.
A small Cessna plane, flying over the area on Tuesday, allowed a cameraman to film fountains of lava shooting 44 miles into the air.
Huge clouds of smoke - mostly vapor and gas, rather than ash, which is dangerous for planes - could be seen coming out of the volcano.
Experts are worried the lava fault expanding to the north might also spread to the south, reaching below the glacier, and that the continuing five magnitude tremors could result in a violent eruption below the glacier.
If that happened, it would result in the melting of an enormous quantity of ice, causing vast floods in the area and major explosions with more volcanic ash.
In the past 72 hours, the volcanic activity has increased dramatically, with the lava now covering an area of more than 1.5 square miles.
The fissure eruption appeared about 28 miles from the main Bardarbunga volcano, which lies under the vast Vatnajokull glacier that dominates the eastern corner of Iceland.
Though remote and sparsely populated, the area is popular with hikers in the summer.
Officials earlier evacuated all tourists in the region following a period of intense seismic activity.
