| The Santa Cruz mountains suffered little damage from the seismic waves, even though they were close to the epicenter. |
| The scientists compared the time it took seismic waves generated by nearly identical earthquakes to travel through the Earth's inner core. |
| Many countries around the world have seismographic networks that monitor and record seismic waves. |
| For three years, the seismometers recorded how seismic waves from hundreds of earthquakes worldwide bounced through the mantle. |
| These seismic waves in the crust are what people feel when they experience an earthquake. |
| Most crustal rocks of interest to exploration geophysics are either inherently anisotropic or behave as anisotropic materials when sampled by seismic waves. |
