Hello and this is our project on tsunamis
What is a Tsunami?
A tsunami is a series of high sea waves caused by underwater earthquakes, volcanic eruptions, rock slides, and some scientists believe that meteors can also cause tsunamis too. They are also called tidal waves.
How Tsunamis Work?
When the underwater earthquake occurs, it pushes the water upward and makes a little wave. Then the wave gradually becomes bigger until it is a gigantic tsunami (average height is about 20 feet). The wind pushes the water particles into a circle which slowly creates an arc on the side of the tsunami as seen in this picture.
How are they detected?
An organization called the National Oceanic and Atmospheric Administration ( NOAA )have detection buoys that sense the wave height or sea level and a network of sensors to track any tsunamis to warn people immediately so there are hopefully no casualties at all.
How frequently are they generated?
There are usually 2 tsunamis a year, and every 15 years, there is a super, really strong and devastating tsunami that wreaks havoc.
How to prepare for a tsunami
Follow the following instructions:
- Plan an evacuation route
- practice that route
- take a radio to keep informed of the situation
- and talk to an insurance agent
PS. you don't have to prepare unless you are at a place that borders the sea or ocean.
- A tsunami is not only one wave, but can have 5-6
- The highest tsunami in the world is 528 meters tall!
- A tsunami can travel as fast as a jet. (500 miles per hour)
- It has two plural forms, tsunamis and tsunami
- Most tsunamis happen in the pacific ocean in the Ring Of Fire
HOPED YOU LEARNED SOMETHING!!!!!!!! :):):):):):):):):):):):):):):)
