There are body waves including P wave and S waves. There are surface waves which include love waves and rayleigh waves. Waves have crests and troughs and wavelengths. Different waves travel at different speeds. 
           Sometimes they cause earthquakes. Underwater earthquakes can cause tsunamis. Any sharp jolt in the ocean can cause a tsunami. A tsunami can travel 500 miles an hour. Boxing Day and a Japan tsunami caused a lot of destruction. Warning systems were created such as DART that can predict tsunamis.

Body wave- Type of seismic wave that travels through the body of a planet; body waves include primary waves and secondary waves

Crest- highest point of a wave

Love wave- Surface wave that has a side-to-side motion, much like a slithering snake

Primary wave- (P-wave) Fastest type of body wave, capable of traveling through solids, liquids, and gases

Rayleigh wave- Surface wave that has a rolling motion

Secondary wave- (S-wave) Slower moving, transverse body wave that can only travel through solids

Surface wave- Seismic wave that travels around the ground surface; the two types are Love and Rayleigh
waves

Trough- Lowest point of a wave

wave length-Horizontal distance between two waves, as measured from crest to crest or trough to trough

A deadly set of waves can rise high on a beach and travel far inland

the boxing day tsunami was created by the biggest  recorded earthquake ever
