From people on the the ground to satellites in the air - how do we monitor and understand volcanos in an attempt to understand when they might erupt?
Professor David Pyle discusses how combinations of different types of information is pieced together to help volcanologists better understand how different volcanoes behave. Each volcano has it's own 'fingerprint' so a more detailed knowledge of their behaviour can be used to inform policies for communities that live near volcanoes, helping to avoid tragedy.
