The effect of tsunami

What is a Tsunami ?

Tsunami is a sea wave of local or distant origin that is an outcome from large-scale seafloor displacements related with large earthquakes, major submarine slides, or exploding volcanic islands. The definition of tsunami and its geographical meaning is also discussed here. The causes of occurrences of Tsunami and their after effects are mentioned in the passage.

When an earthquake occurs, the energy travels outward in all directions.

For the epicentre,the energy causes a sea wave to move away at great speed.

Tsunami can be generated when the sea floor abruptly deforms and vertically displaces the overlying water.

The 2004 Indian Ocean earthquake, known by the scientific community as the Sumatra-Andaman earthquake, was an undersea earthquake that occurred at 07:58:53 local time on December 26, 2004.

The earthquake generated a tsunami that was among the deadliest disasters in modern history, killing well over 200,000 people.

2004 Indian Ocean earthquake-affected countries

The earthquake and resulting tsunami affected a large number of countries in Southeast Asia and beyond, including Indonesia, Sri Lanka, India, Thailand, the Maldives, Somalia, Myanmar, Malaysia, and others.

Introduction of the tsunami video

Location: Thailand

Video Description: A really quick shot of the wave coming in and crashing into a garden between two large hills. Three people are standing in the garden as the wave comes in, and the video stops as the wave gets close to them.

The destroyed of Tsunami

The tsunami impacts can divided in few main areas: 1)Humanitarian Impact ： Since many people hurt or die in there. also, the sea water

made the infrastructure fell down, and shortages of food and drink water,Therefore, they needed a great deal of humanitarian aid.

2) Economic impact: The impact on coastal fishing communities and

fisher folk , has been devastating with high losses of income earners as their boats and fishing gear In Sri Lanka's coastal areas.But some economists believe that damage to the affected countries' economies will be minor because losses in the tourism and fishing industries are a relatively small percentage of the GDP.

Tsunami impacts3) Environmental Impact ：Tsunami Inundation, North of Phuket, Thailand ASTER Images and SRTM Elevation As many human lives destroyed by the tsunami. It has caused the environmental impact that will affect tin the following years. It has been reported that severe damage has been inflicted on ecosystems such as mangroves, coral reefs, forests, coastal wetlands, vegetation, sand dunes and rock formations, animal and plant biodiversity and groundwater.

4)Spiritual / psychological impact

Many health professionals and aid workers are reporting widespread psychological trauma associated with the tsunami, and many sightings of ghosts have been reported, particularly those of foreigners. Traditional beliefs in many of the affected regions state that a relative of the family must bury the body of the dead or the ghost will return.

The amount damage tsunamis caused is partly related to the intensity of the earthquake that produced them.Some other contributing factor include the nature of the coastline and the distance from the epicentre.

Damage caused big tsunamis include: 1) People living in coastal areas are badly

affected.Houses are destroyed and people become homeless.There will be a great loss of life casualties.

2) Pier or the seaport facilities will be battered by giant waves.Ships will be overturned and dock is torn up.

3) Scattered debris hinder rescue and recovery work. 4) Coastal villages and cities are destroyed. For

example,buildings are destroyed, bridges collapse,sections of highways are flooded and railways crack.There will be a huge economics loss.

As at noon, 4 June 2005, there were 12 unlocated Hong Kong residents. All were reported to be in Thailand. As of today, a total of 28 Hong Kong residents were reported to have deceased.

‧Poor Warning system‧The economics development is poor‧The buildings structure is not unfluctuating‧The people awareness is very low‧The government don’t teach the public about the serious effect of tsunami

‧Evacuate people from the affected area and provide emergency aid such as supplying food,water,blanket, shelter and other basic necessities to victims.

‧Send rescue teams to search for survivors, especially in the rubble after an earthquake and give immediate medical services to the injured.

‧Carry out other relief work such as restoring communication and transport , putting out fire and providing medical services to prevent the spread of disease.

Long term measures to minimize loss Countries around the Pacific Ocean have set up

the Tsunami Warning System to record potential tsunamis generated by earthquakes.

We can take some various long term measures to minimize their negative effects：

‧Setting Earthquake prediction and warning system‧Improving modern technology and construction

regulations‧Land use zoning‧Education and emergency plans

After seeing these photos, what do you think about Tsunami?

We felt very sad.In this photo, We saw many people died and they hurted by Tsunami.

Moreover,people became homeless.Also,the building fall down and bridge collapsed.

We are the member of society,I think we should a duty to help the sufferer.We can donate money to the non-profit making organization.Also, we must pay more attention to our life.

We use this song to become the background music because we think that it is related to Tsunami.The song was about children.After listening the song,we think that we should save our life.Also, we should try our best in everything, such as this song’s lyrics.Here are the main part of the song:

We are the world, we are the childrenWe are the ones who make a brighter daySo lets start givingThere's a choice we're makingWe're saving out own livesits true we'll make a better dayJust you and me
