Tsunami Olivia & Mana

What is this tragic series of waves?

It's a tsunami! A tsunami is a series of waves that hit coastlines hundreds of miles away! They expand more and more as they reach an area of land. Their largest point is when they are on the coastline because the water gets shallower and the waves pile up. Then they CRASH! The waves of a tsunami move in all directions. A tsunami is not very well seen in an open ocean, so it's hard to prepare for one!

How are they created?

Tsunamis are created by an earthquake underwater. The earthquake is created by the moving of tectonic plates. The tectonic plates push and pull against each other until they move out of place. This releases a lot of energy and creates a displacement of water. Waves are the result that get larger and faster as they reach an area of land.. A tsunami can also be created by other natural disasters (ex. volcanic eruptions, landslides, etc.)BOOM, A TSUNAMI IS BORN!!!!!!!

What do they result in?

Depending on the amount of force given, the effects and causes are different . Small tsunamis can be destructive but with specialized equipment, the amount of damage can be reduced. Architects have been creating troughs and barriers or even just raising houses to prevent the damage. When the waves are large in height, it can cause devastating property damage and loss of many lives. Another devastating event that can happen is starvation and disease after a tsunami has occurred. The reasons for this is because they can poison fresh-water surface and ground water systems as well as the soil by leaving large amounts of salt behind.


Characteristics of a Tsunami

Tsunamis are also known as rising tides, harbour waves, seismic sea waves or tidal waves. Tsunamis can last minutes to hours! A wave of a tsunami can reach up to 100 feet! A tsunami can move up to 560 mph! When it reaches a coastline it slows down to 30 mph.

The riskiest and most common areas a tsunami hits

What do you do in preparation for a tsunami?

If a tsunami warning is issued in advanced, get as far away from coastlines as you can. Maybe about 2 miles away. You should also try to stick to higher grounds. Lastly, make sure you have water, food, and a safety kit.
