  3. QUIZ 1 REVIEW • Draw and label the following features in a single sketch: Mid-ocean ridge, trench, subduction zone, oceanic lithosphere, continental lithosphere, mountains/volcanoes. Draw arrows showing direction of plate movement. http://www.tulane.edu/~sanelson/geol204/eqhazards&risks.htm REVIEW | 3 Department of Earth Sciences

  4. LAB 3 - EARTHQUAKES - KEY CONCEPTS • Understand the effects of shaking on various objects • Underlying geology changes seismic wave properties • Liquefaction EARTHQUAKES | 4 Department of Earth Sciences

  5. SEISMIC WAVES • Release of accumulated energy leads to quake • Energy travels in waves of vibration • Body waves • P-waves - primary • S-waves - secondary • Surface waves • Love • Rayleigh EARTHQUAKES | 5 Department of Earth Sciences

  6. SEISMIC WAVES • Damage usually highest from waves of highest amplitude From the seismogram, which wave is most destructive? EARTHQUAKES | 6 Department of Earth Sciences
