| Question | Answer |
|---|---|
| Fault | A fracture in bedrock, along which blocks of rock on opposite sides of the fracture move. |
| Intensity | A measure of the damage done by an earthquake that is determined on the basis of the earhquake's effect on people, structures, and the natural environment. |
| Magnitude | A measure of the total amount of energy released at the focus of a earthquake. |
| Destructive | Causing damage or injury. |
| Stress | The amount of force being applied to a rock or surface. |
| Tsunami | A long high sea wave caused by an earthquake, submarine landslide, or other disturbance. |
| Seismogram | The record is made by a seismograph; the paper on which data about earthquake waves is recorded. |
| Seismograph | An instrument used to detect earthquake waves. |
| Tension | refers to the stress building in rocks that causes them to slip, releasing energy as seismic waves. |
| Compression | the squeezing stress that pushes rocks together, causing them to fold, fracture, or slide, often creating reverse/thrust faults. |
| Shearing | A type of tectonic stress where rocks slide horizontally past each other along a fault plane, causing one surface to move sideways relative to the other, like a deck of cards being pushed sideways. |
