What are Earthquakes?
• Earthquake-sudden movement of the ground caused by the release of energy when the rocks move along a fault.– Fault-a break in rock where movement
occurs.
Where do most earthquakes occur?
• Most earthquakes occur at plate boundaries, where there is a lot of stress.
• Some happen at fault zones
• Focus-where the first movement occurs in the earth’s crust.
• Epicenter-point on the earth’s surface where the earthquake is felt first.
Seismic Waves
• Body waves-travel thru the earth’s interior.Includes:– P waves-primary• Fastest waves, first to be detected.• Move back and forth parallel to the motion of
the wave.• Move thru solids, liquids and gases.
– S waves-secondary• Second fastest• Move perpendicular to motion of wave.• Move only thru solids
• Surface waves-travel along the earth’s surface.– Slowest moving waves– Move rock side to side and up and down– Cause the most damage during earthquakes
Seismology
• Seismology is the study of earthquakes.
• Seismograph-instrument that records seismic waves.
Measuring Earthquakes
• Magnitude-strength of an earthquake.– Richter scale
• Intensity-how much damage an earthquake causes.– Mercalli
scale
