<p>The Wave That Shook The World – December 26, 2004 (NOVA) Discussion 5 points </p><p>The rupture occurred at a depth of 30 km and the fault line broke along a 1200 km stretch of the sea floor. There was 10-20 meters of displacement along this thrust fault, a type of low angle reverse fault that dips about 10 degrees to the NE. The shaking lasted about 4 minutes.</p><p>Draw a cross-section showing the India-Australian plate subducting beneath the Burma- Sundra plate of Indonesia. This image will show up again in the movie if you don’t get it all the first time.</p><p>What kind of stress was involved with this earthquake? tension, shear, or compression</p><p>Since this area had not experienced a quake of this magnitude in over 100 years, was this an example of fault creep or stick-slip movement?</p><p>Approximately how long does it take seismic waves to travel through and around the world?</p><p>The tsunami that was produced is similar to what type of seismic wave? P, S, or L Some coastlines close to the epicenter were not as severely damaged as others at a similar distance from the epicenter. What was different?</p><p>How did the quake affect the Earth as a whole object?</p><p>Should we consider this earthquake to be an anomaly, a freak occurrence? Why or why not?</p>
