The Earth is a dynamic planet continually pulsating to its own rhythm as tectonic plates grind against each other, mountains and hillsides crumble and collapse and volcanoes explode.   Join the British Geological Survey – leaders in seismology – to learn how we measure seismic shaking. Hear the earth shaking in real time (we can guarantee there will be an earthquake somewhere in the world every day), discover how seismometers work, find out how scientists discovered that the core of the earth is a liquid, and then and make your own (mini) earthquake!
