How can volcanic eruptions be predicted?
Earth Learning Idea (noreply@blogger.com)
Continuing our natural hazards theme, our ELI today is 'When will it blow? – predicting eruptions; how a simple tiltmeter can demonstrate the bulging of a volcano before eruption'. There is also a teaching video demonstrating this activity. You might enjoy watching another video too! This activity demonstrates how a simple ‘tiltmeter’ can show the bulging of a volcano before eruption – using trays of water to highlight ‘bulging’ as a bag or balloon is inflated.
