whereas the Love waves cause the ground to ripple back and forth (like the movement of a snake). 8. Ask the students to recall how scientists use seismic wave observations to investigate the ...

but bounced off of features in the Earth or at the surface and arrived at the seismic station a little later. The surface waves (Love and Rayleigh waves) are the other, often larger, waves marked on ...

Basically, a seismic wave is generated underneath the earth's surface, and then picked up by sensors called "geophones" as the waves bounce off subsurface formations -- that is, layers of rock ...

Los Angeles sits above an enormous bowl of sediment that alters how seismic waves move under the city (Credit: Getty Images) Southern California is frequently shaken by earthquakes. How they feel ...

A surface wave travels along the surface of the Earth. It is the slowest of the three types of seismic wave. Surface waves usually have larger amplitude than the other waves and cause the most damage.

While earthquake locations are normally done with a computer that can quickly determine the paths of seismic waves through the Earth to many seismic stations, you can get a good estimate of an ...

which uses "electrical energy . . . as a wave source" that "monitor[s] seismic wave energy" on dry, wet, and frozen diabase samples. Experimentation revealed that the seismic velocities of the dry ...
