Waves

An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.

They can cause huge waves in the ocean called tsunamis.

In its most general sense, the word earthquake is used to describe any seismic event—whether natural or caused by humans—that generates seismic waves.

You can hear the waves at night.

It just needs a window and the sound of waves.
