Modern seismometer

Modern seismometer. Three components of motion can be measured. east-west. north-south. up-down. If you speeded up any earthquake signal and listened to it with a hi fi, it would sound like thunder. Station 1. Station 2. Station 3. Station 4. Station 5.

Earthquakes and earthquake (or seismic) waves

Earthquakes and earthquake (or seismic) waves. EARTHQUAKE: Vibrations caused by the sudden release of energy stored in the rocks. SEISMIC WAVES or EARTHQUAKE WAVES : Energy that moves through the earth because of an earthquake. Surface waves. Travel along the surface of the earth.

Forces Inside the Earth

Forces Inside the Earth. Earthquakes. California, USA. The red line is the San Andreas Fault, dividing two crustal plates. Everything to the left (west) of the fault line is trying to move northwest. Everything to the right (east) of the fault line is trying to move southeast. The result:

What are Earthquakes?

What are Earthquakes?. Where do most earthquakes occur? By looking at maps showing past seismic activity, one can see that earthquakes occur mostly at the boundaries of tectonic plates, where the plates move with respect to each other. What are Earthquakes? continued.

The Speed of a Wave

The Speed of a Wave. Calculating Speed. Wave Speed = Frequency x Wavelength Speed = Number of Waves per Second X Distance Between Waves. Factors that Affect the Speed of a Wave. Density: The closer the particles the faster the wave can travel.
