A Tsunami is formed by underwater earthquakes and underwater volcanic eruptions. Tsunamis are also known as a tidal wave but is nowhere near related to the tidal activity caused by the sun and moon.a tsunami is basically just a bigger version of a normal wave They have a trough and a crest and both move by the energy in the water . The only Difference is where the energy comes from.

Some of the warning signs for a tsunami are the buoys in the when a tsunami is is travelling under it through the water or around it though the water the buoys will start to move rapidly through the water. There is also something called a seismograph which some scientists use to detect tsunamis early.
