Our new activity is now ready for you to try - 'When will it blow? - predicting eruptions'. It shows how a simple tiltmeter can demonstrate the bulging of a volcano before eruption. Our short video clip shows the bulging in action.
This is a brilliant, simple activity and could form part of a lesson about volcanic eruptions and their effects. It could also be used as part of the preparation for the best response to an eruption in a volcanic area. Pupils will be able to relate this simple classroom demonstration to the fact that tiltmeters are used on volcanoes all over the world to help to predict eruptions.
