1. 1. EarthquakesBrittany ConnellyAleksandra Kocz Mrs. Smith 3rd Hour April 8, 2011
2. 2. Basic Background Information-What is an earthquake?The shaking that results from the movement of rock beneath Earth’s surface .-How are earthquakes measured?Seismic Waves .-What does magnitude mean?A measurement of earthquake strength based on seismic waves and movement along faults .-How is magnitude measured?Movement Magnitude Scale .
3. 3. Damage Caused by Earthquakes• Tsunami .• Death .• Damaged Nuclear Power Plants .• Buildings Fall Apart .
4. 4. WavesWhat are earthquake waves called?Seismic Waves .What two types of seismic waves are there?Primary and Secondary .What two types of body waves are there?Primary and Secondary .
5. 5. Body WavesHow do P waves travel?Stretch and compress the rock in their path through Earth .How do S waves travel?Move the rock in their path up and down and side to side .Which move faster?Seismic Waves .
6. 6. Elastic ReboundTheory of earthquakes that envisades gradual deformination of the fault slippage until friction is overcome , when suddenly slips to produce the earthquake .The elastic rebound theory of earthquakes sources allows rough prediction of the occurrence of large shallow earthquakes .The uplift associated with earthquakes and mountain building. Uplift of the Earth’s surface also has occurred in response to the removal of Pleistocene ice sheets through melting and wastage .Elastic rebounds occur in the QuickTime™ and a decompressor are need ed to see this picture.
