Tsunami

Anna Bruce, Taylor Garrison, Austin Grover, Gean Lee

Physical Characteristics

· Tsunami is a giant title wave that can be ranked on a scale a 1-9 magnitude

· They increase in size as they get closer to land

· Tsunamis can grow massively when in shallow sea bed

· Tsunamis are small and cannot be decteceded easily out in the sea.

· Tsunamis when fromed from go horizontily away they also when the water goes up it will spilt right down the colom creating atsunamie on either side that travel horizontally.

· Tsunamis have a long wave length

· They have large amounts of water behind them and are very heavy

· Tsunamis have multiple waves

· Tsunamies go inland for as far as possible dependeding on mass and magnitude and then drag everything back out to sea

· A level 9 tsunamie has a magnitude of 30 level 8 tsunamies

· Tsunamis can grow through emancipation

· Most tusnamies occur in pacific

· Tusnmaies can be casued by metors earthqukaes eruptions land slides


Awareness and Saftey

· The International Tsunami Warning System monitors oceans through a network of buoys and scientific instruments.


· When the instruments detect a major earthquake and the potential for tsunami to occur, warnings are issued to local authorities who can order the evacuation of low-lying areas if necessary· If in a coastal area and feel an earthquake:

· When the instruments detect a major earthquake and the potential for tsunami to occur, warnings are issued to local authorities who can order the evacuation of low-lying areas if necessary· If in a coastal area and feel an earthquake:

1st protect yourself from the earthquake. Drop, cover, and hold on.

2nd when shaking stops, move to a higher ground away from coast.

3rd Be prepared for after shocks, when you fell the earth shake drop, cover and hold on.

· Be aware of the signs or a tsunami:

A strong earthquake lasting 20 seconds or more near the coast.

A noticeable rapid rise or fall in coastal waters.

A loud roaring noise from the ocean.

Tsunami Occurance

· Most Tsunamis occur where tectonic plates meet or at other geological faults exist.

· Tsunamis can occur because of Earthquakes, volcanoes, Asteroids, and landslides.

· Most Tsunamis occur in the Pacific Ocean.

· People are able to research tsunamis patterns and predict when they will next occur.

· Tsunami Danger period continues for many hours as the water moves on to land, recede and return.

· The second and third waves can be more devastating than the first

· Tsunamis can occur any time of the year

· Aftershocks happen frequently each time the earth shakes near the coastline is a sign of a tsunami.



Tsunami impact on life

· Tsunamies can cause disease

· Phsycological damage to humans

· Reshape land

· Kills marine life

· Kills animale life and plant life

· Kills human

· Can cause a lack of transportation

· Poverty

· Peoples lives to be ruined

· Devaste the land scape taking it forever for a village to rebuild and start over

· No roads to drive

· Starvation

· A lot of wounded people

Questions

1. What are some characteristics of ways that factor into how much damage a tsunami causes?

-Height

-sea bed

-magnitude of a earthquake

-population of area

-and wave length


2. How do coastal or shore line features factor into the extent of damage a tsunami causes?

-If the coastline is a city

-(less populated places have less buildings and people to effect)

3. What role could a tsunami warning system play?

The warning system would alert people before it happend so they could find saftey which will save maney lives.
