Earthquakes - The shaking and trembling by the sudden release of energy , associated with movement along a fault line. -After shocks are continuing fault slippage Elastic Rebound theory - Stress builds up and begins to deform the rock - when the break occurs the rock snaps back to undeformed shape - The energy is released into waves that move outward from the fault Focus – the point in which the fault begins Epicenter- the point directly above the focus on the surface Seismographs record earthquake events Most earthquakes occur in the Circum-Pacific Belt (80%) Others at the Mediterranean- Asiatic belt (5%) Some by the interior of plates and others on the spreading of Mid-Ocean Ridges Earthquakes causes -Building to collapse -Fires -Ground failure (landslides) -Tsunami’s Seismic waves are vibrations produced by fault movement P WAVES – expansion , compression , expansion , compression… -Fastest -Travel through Liquid , solid and gas -compressing waves S WAVES -slower - travel through solids only - Transverse waves SURFACE WAVES (L) -slowest - travel only at the surface - damaging to structures P WAVES arrive first then S WAVES then L WAVES – speed varies Size and strength of Earthquakes 1.
