It's one of the world's most active volcanoes... And was the stuff of legend all the way back in Roman times. But Mt Etna in Sicily has sat quiet for nearly two years. That was until late February when it started erupting again. Volcanologists in Italy are using drones and thermal imaging cameras to study changes on Mt Etna and see what's causing the eruptions. (Soundbite) Volcanologist, Emanuela De Beni, saying (English): "On the backside you can see the new southeast crater and the southeast crater. In the 15th of March lava flow began to flow from the lower flank of this crater and now we are here to monitor the lava flow field with the staff of the Etnean Observatory. During this day we perform thermal image, GPS measurement and lava flow mapping, also using drone to better understand how the flow field evolved during this eruption." Etna is Europe's highest volcano and can burst into action several times a year. The last major eruption was in 1992.
