Terms | Definitions |
Elasitic Rebound Theory | This theory, the rocks on each side of a fault move slowly |
Seismic Waves | When rocks along a fault release engery in form of vibrations |
Aftershocks | Smaller tremors |
Focus | Area along a fault where slippage first occurs |
Epicenter | Point on earth's surface directly above the focus |
Pacific Ring of Fire | This ring includes west coasts of North and South America, east coast of Asia, and the western Pacific islands of the Philipean, Indonesia, New Guinea, and New Zealand |
Fault Zones | Some plate boundaries there are groups of interconnected faults |
Seismograph | Seismic waves can be recorded by using this instrument |
P Waves (Primary) | These waves move the fastest and are the first waves to be recorded |
S Waves (Secondary) | These waves can only travel through solid material |
L Waves (Long waves) | These are the slowest moving waves and travel slowly over the earth's surface |
Richter Scale | Expresses the magnitude of an earthquake |
Microquakes | These type of quakes have a magnitude of less than 2.5 |
Mercalli Scale | Expresses the intensity of an earthquake and amount of damage it causes |
Tsunami | A large earthquake with an epicenter on the ocean floor can sometimes cause a giant wave |
Seismic Gaps | A place where the fault is locked and unable to move |
