    What’s An Earthquake, Anyway?Types of Seismic WavesWhy Seismic Waves Are ImportantStudying The Earth with Seismic WavesOther Types of Seismic WavesIn the broadest sense, an earthquake is just what the name suggests — any shaking of the Earth’s interior. Earthquakes can happen for a variety of reasons, but by far the most common cause is tectonic.The Earth’s crust (the outermost layer) is split into rigid plates, all of which are moving relative to each other. The movement produces more and more stress on the ground until something eventually breaks along what’s called a geological fault. This is why, if you overlay a global tectonic pla...
