Across 4. the point beneath Earth's surface where rock breaks under stress and causes an earthquake 8. was developed to rate earthquakes according to the level of damage at a given place 10. the shaking and trembling that results from the movement of rock beneath the Earth's surface 11. a number that geologists assign to an earthquake

Down 1. seismic waves are measured 2. a rating system that estimates the total energy released by and earthquake 3. move more slowly the P Waves and S Waves, but they can produce severe ground movements 5. a rating of an earthquake's magnitude based on seismic waves 6. seismic waves that compress and expand the ground like an accordian 7. the point on the surface directly above the focus 9. seismic waves that vibrates from side to side as well as up and down
