Scientists in Sicily are closely monitoring Mount Etna, one of Europe's most active volcanoes, in order to predict eruptions. They collect a wide range of data including seismic readings, gas measurements, thermal images and more from over 75 seismic stations and sensors placed around the volcano. This data gives insights into the movement of magma below the surface. Changes in the levels and ratios of different volcanic gases can help scientists estimate how close magma is to the surface and predict imminent eruptions. Constant monitoring through this extensive data collection network allows scientists to provide warnings, sometimes months in advance, helping authorities manage risks from the volcano.
