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 ...

Earth’s solid inner core appears to have changed shape in the past 20 years or so, according to seismic wave measurements – but the behaviour of these waves could also be explained by other ...

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.
