| seismometer | same as seismograph |
| seismicbelts | follows tectonic plate boundaries |
| seismogram | the paper that the earthquake is recorded on |
| liquefaction | causes structures to sink in the ground |
| surfacewave | seismic wave that moves in two directions |
| pancaking | vertical collapsing of multifloor buildings |
| magnitude | rates earthquake intensity |
| fault | fracture in rock along which movement occurs |
| strain | deformation of materials in response to stress |
| tsunami | wave generated by vertical motions of the sea floor |
| mercalliscale | rates earthquake intensity |
| swave | waves that cannot pass through the core |
| pwave | waves that are the fastest |
| faultscarps | vertical offset where the fault intersects the ground |
| normal | fault that moves away from each other |
| reverse | fault that moves toward each other |
| strikeslip | fault that moves horizontally |
| stress | pressure that exceeds the the strength of the rocks |
| focus | the origination point of the earthquake |
| epicenter | the point on the surface where the earthquake originated |
