| normal fault | when rock is streched by force |
| reverse fault | surface is foced up and over rock |
| strike slip fault | rocks on either side are moving past echother |
| wave | rythmic movment that carries energy through matter |
| seismic wave | generated by eathquakes traveling through earth |
| focus | were energy is released |
| primary wave | causes particals in rocks to move |
| secondary wave | moves through earth by causing particals in rocks to move |
| surface waves | moves rock particals in backward rolling motion |
| epicenter | point on earths surface directly above earthquake focus |
| seismograph | registers waves |
| crest | highest point in wave |
| magnitude | were energy is released |
| inquefaction | were wet soil turns to liqued |
| isunamis | ocean waves caused by earthquakes |
