earthquakes
chapter 6
| Question | Answer |
|---|---|
| aftershock | termor that follows and is smaller than a major eathquake |
| earthquake | vibration of the earth's crust |
| elastic rebound theory | theory that rocks that are strained past a certain point will fracture and spring back to their original shape |
| epicenter | point on the earth's surface directly above the focus of an earthquake |
| fault zone | group of intherconnected faults |
| focus | area along a fault at which slippage first occurs, initiating an earthquake |
| intensity | amount of damage caused by an earthquake |
| magnitude | a measure of the energy released by an earthquake; desscribed as the amount of ground motion |
| mercalli scale | scale the expresses the intensity of an earthquake with a roman numeral and a description |
| microquake | earthquake with a magnitude less than 2.5 on the richter scale |
| P wave | primary wave; the fastest wave generated by an earthquake and the first to be recorded by a seismograph |
| pacific ring of fire | major earthquake zone that forms a ring around the pacific ocean |
| S wave | secondary wave; a wave generated by an earthquake and the second to be recorded by a s |
| seismic gap | |
| seismograph | |
| surface wave | |
| tsunami | |
