Tsunamis are giant waves from the sea and are very destructive. A tsunami is caused by earthquakes or meteors. Tsunamis are giant ocean waves caused by a large earthquake, they are also known as seismic sea waves.
The name “Tsunami” is Japanese and means “Harbor wave”, there also are tidal waves which are similar to tsunamis. Tsunami is Japanese but it’s now used in English. The term “Tsunami” is from Japan and means harbor (tsu) wave (nami).
Tsunamis occur by meteors or earthquakes. They are caused by sudden movement from the ocean, basically underwater earthquakes. Tsunamis happen mostly in the Pacific Ocean, the Mediterranean Sea and the Caribbean.
People measure tsunamis with a recorder. The recorder transmits with buoys, the buoys relay measurements of wave height to the satellites.
The maximum height of a tsunami is 1720 feet (543 meters) which probably was the highest tsunami ever. The normal height of a tsunami is 30 meters but 543 meters (1720 feet) is a whole lot higher.
Tsunamis are giant waves from the sea and are caused by underwater earthquakes.

Underwater Earthquakes: earthquakes that are underwater in the ocean.
Meteor: a small body of matter from outer space that enters the earth’s atmosphere, becoming incandescent as a result of friction and appearing as a streak of light.
Transmit: cause (something) to pass on from one person or place to another.
