A device that records ground movements caused by seismic waves as they move through Earth travel through liquids and solids, push and pull, faster, arrive first A wave that requires a medium through which to travel Breaks in Earth's crust where rocks have slipped past each other. vibrations that travel through Earth carrying the energy released during an earthquake The study of earthquakes travel through solids only; cause rock to move in a side-to-side or up & down motion, slower waves Point on Earth's surface directly above an earthquake's focus
