Document Summary
Be able to define what an eq is and that they can be caused by (cid:1) various factors, including, but not limited to movement along faults. Earth shaking caused by a rapid release of energy : due to tectonic stresses that cause rocks to break, energy moves outward as an expanding sphere of waves, can be measured around the globe. Eqs destroy buildings & kill people: 4. 2 million deaths in the last 2,000 years. Common: plates are always moving, potential for seismic waves to always be released (cid:1) (cid:1) seismic waves. Be able to differentiate among the four different types of. Body waves inside the earth: p waves causes things to move back and forth, s waves shear wave, like a snake, secondary wave. These help you pinpoint where an earthquakes occurs. Surface waves cause the most damage: larger magnitude , more damage (cid:1) (cid:1) travel-time curves from 3 stations to locate and eq epicenter.
