This clip builds on the concept of constructing lava barriers which is introduced in the main programme. It`s not possible to prevent an eruption from happening, but scientists can predict when one will happen and suggest the best course of action for protecting the local towns from the destructive lava flows. Computer modellers at the Institute of Volcanology in Catania use data collected from the volcano, such as thermal imaging, to predict the path of the lava flows. Civil protection authorities then use this information to construct barriers of old lava to divert the flow of fresh lava away from the towns.
