| 21. | The seismic waves from Landers, Linde says, did just that.
|
| 22. | However, if the seismic waves were reflected back at him, he would be injured.
|
| 23. | Tsunamis are seismic waves caused by undersea disturbances such as volcanic activities or earthquakes.
|
| 24. | During the earthquake of 1985, the seismic waves were trapped in the soft strata.
|
| 25. | Venezuelan unrest could also set off seismic waves across the U . S . economy.
|
| 26. | Tsunami are seismic waves caused by undersea disturbances such as volcanic activities or undersea earthquakes.
|
| 27. | Natural or artificially created seismic waves can be used to map structures in the Earth.
|
| 28. | Velocity of seismic waves in the Earth versus depth.
|
| 29. | Maria de la Luz Calderon rode the seismic waves that rolled through her apartment building.
|
| 30. | The frequency-dependent attenuation of seismic waves leads to decreased resolution of seismic images with depth.
