The 2010 eruptions in Iceland disrupted air travel for weeks, costing the global economy an estimated $4.9bn. In response enormous improvements are being made in the technology used to detect imminent volcanic eruptions. But is the technology enough on its own? Do changes need to be made in the way that vulnerable communities in the developing world are taught about the dangers on their doorstep? Can more be done to communicate risk without inducing panic?
From Nicaragua to Iceland, Montserrat to Santorini, Tom Heap hears from the scientists on the frontline, men and women enchanted by the stunning beauty of volcanoes but well aware of their potential to destroy communities and change our climate.
