EARTHQUAKES
![Page 5: What is the Great Shake Out?](https://reader030.vdocuments.mx/reader030/viewer/2022033108/56649f435503460f94c62c53/html5/thumbnails/5.jpg)
Earthquake
• Release of energy when pressure and/or stress is built up between rocks
• Usually occurs along faults and plate boundaries
• Causes the area of rock to snap when energy is rapidly released in all directions along seismic waves

Earthquake Terms• FOCUS – actual location of where the
earthquake originates
• EPICENTER – Surface directly above focus

Types of Faults
Normal Fault Reverse Fault Strike-Slip Fault
FAULT - Fractures or cracks on earth’s surface that occur due to tectonic plate motion

Faults
• Normal fault– Found in areas
under tension• Where sections of the
landscape are pulling apart (divergent)
Called Fault Block Mountains

Faults (cont.)
• Reverse fault– Found in areas under
compression• Zones of convergence
Like the Himalaya Mountains

Faults (cont.)
• Strike-slip faults– More horizontal
movement than vertical movement
Like the San Andreas fault in California
