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.
