What do seismic waves caused?

Answer 1

Earthquakes are caused by movements of the earth to relieve pressures.. for example pressures from the movement of tectonic plates under the crust, or pressure changes with the movement of magna in a volcano.

This movement in the earth is detected as seismic waves.

I suppose since the definition of seismic waves is just a wave in the earth, it could also be made by man-made phenomena. For example a large explosion, or a large impact could create seismic waves that extend beyond the point of origin.

If the seismic waves occur on land, they cause vibrations, or the sensation of the movement of the earth that can be felt over great distances, and they can cause severe the destruction of property depending on the distance from the epicenter of the earthquake and the strength of the earthquake.

If they occur in the oceans, or run into the oceans, they can cause Tsunamis or Tidal Waves which can travel over great distances. Propagation of waves in deep water is often hard to perceive due to their cyclical nature, but they can climb and can be very devastating when they hit land which can be a significant distance from the original earthquake.

Now, you have this under "science experiments". I wouldn't recommend trying to blow anything up. However, it is possible that you could hit a block of wood on the ground with a sledge, and have the impact travel in a wave to something nearby, for example dominoes standing upright nearby (arranged so they wouldn't fall onto each other. High speed Photography would be cool to use with it, but may not be accessible. You would, of course, have to control for wind somehow.

You may be able to also simulate seismic waves with Jello.... Consider making a house out of cards sitting on a tray of Jello, and inducing a wave.

While water and Jello couldn't be in contact for long, you might be able to induce a water wave starting with a wave in Jello.

Answer 3

Seismic waves cause earthquakes to be stronger by releasing energy......... [:
