WebEarthquake detection. A seismogram is a record of the ground motions caused by seismic waves from an earthquake. A seismograph or seismometer is the measuring instrument that creates the seismogram. Almost all seismometers are based on the principle of inertia, that is, where a suspended mass tends to remain still when the ground moves. WebSoon a little bit of foam rubber along the crack (the fault) will break and the two pieces will suddenly slip past each other. That sudden breaking of the foam rubber is the earthquake. That's what happens along a strike-slip fault. Seismic waves can also be caused by natural processes other than earthquakes and by human activities.

And our focus here is going to be on the seismic waves, but the principles, how things refract when they go from a fast to a slow medium or a slow to a fast medium, It's actually the same as you would see when you're studying light waves or actually any type of wave.
