New project to help predict volcanic eruptions
Work is under way to improve monitoring of Iceland's volcanoes and give earlier warning of possible eruptions.
The FutureVolc project is funded by the European Union and involves more sensors as well as better real-time data analysis.
It is a response to the 2010 eruption of Eyjafjallajokull, which closed down much of European airspace.
The BBC's Neil Bowdler reports from the heart of a dormant volcano.
