During responses:
When the Indian Ocean Tsunami struck, the only warning that people had who were in the region had was the sight of this big wave heading towards them in fast speed.
Survivors who were found, were moved to hospitals and injured people were being aided.
The government were doing everything they could to help each and every person.
Helicopters were being used to search for missing or injured people.
After responses:
Numerous governments and non governmental agencies around the world offered aid, service and other support to countries affected by the tsunami. An example of sponsors would be New Zealand, NZ donated $62,000,000 to support the United Nations and other international programmes. NZ public donated millions of dollars through a range of charitable organisations.
Government agencies helped donate $1.4 billion to the relief effort.
In the aftermath of the disaster, scientists and governments began working on an early warning system for the people living in the region so that they can predict and be more aware about when a tsunami is anticipated. In June 2006, the Indian Ocean Tsunami Warning System was launched to provide warning to the inhabitants of the coastal areas which border the Indian Ocean.
Seismic gauges can detect the earthquakes or volcanic eruptions which may cause a tsunami.
Other sea-based instruments are needed to help scientists decide if a tsunami has been triggered.
1. Recorder on sea bed measures water pressure every 15 mins - an unusual result triggers a reading every 15 secs.
2. Buoy measures surface conditions and sends this plus data from sea bed to satellite
3. Satellite receives data and relays it to ground stations
This extreme natural event occurred on the 26th of December 2004 which unfortunately happens to be the day after Christmas; Boxing Day, thus why it is called the Boxing Day Tsunami, was one of the worst tsunamis the southern Asia countries encountered.
The tsunami occurred in the Indian Ocean, affecting the countries situated there. It affected 13 countries: Kenya, Somalia, Tanzania, Seychelles, Maldives, Andaman and Nicobar Islands, Bangladesh, Myanmar (Burma), India, Bangladesh, Thailand, Malaysia and Indonesia.
The scale of the destruction caused by the tsunami was huge.
Many of the world's poorest people lost everything.
Effects on the natural environment
Many lives were saved from the effects of diseases and hunger as a result of the immediate international humanitarian response that followed the disaster. Due to the tsunami being widespread, humanitarian aid was used to build infrastructure and provide food, shelter and medical supplies. Diseases like typhoid were of particular concern from international aid groups so to avoid it, they provided sanitation facilities a fresh clean drinking water.
A tsunami is a huge wave usually caused by volcanic or earthquake event. When an earthquake that causes the ocean floor to suddenly rise and fall, it can set off a tsunami. In deep water, the tsunami waves can be less than one metre but it can travel around 800kph. When a tsunami wave hits shallow water near the coast, it slows down but the wave increases in height. Tsunami waves don't often crash onto shores but instead they swamp around big areas of land which causes widespread destruction. (Water from tsunami waves can reach far inland.) The tsunami was caused by a 9.0 magnitude earthquake. A tsunami forms when the energy of an underwater earthquake jolts the seafloor vertically by several metres displacing the massive volume of seawater above. When the displacement of water reaches the surface of the sea, large waves are formed and move away from the earthquake's epicentre.
In deep water, a tsunami's waves can travel at many hundreds of kilometres per hour. However when the waves approach the shallow waters of the coastline, tusnami waves will slow down and increase in height. When the deep sea earthquake struck wih a magnitude of 9.1 travelling at an estimated 500-1000km per hous from the epiccentre slowed down to a mere 10kmph when it neared the coastline, but also increased in height to 24m when it neared the coastlines of Aceh Province in Indonesia.
The tsunami had a significant effect on coastal ecosystems bordering the Indian Ocean.
- The tsunami waves destroyed the dune (a mound or ridge of sand or other loose sediment formed by the wind, especially on the sea coast or in a desert.) systems, coral reefs, mangroves and coastal vegetation but also resulted in the contaimination of groundwater supplies as a result of flooding.
By Nancy Sau
- A quarter of million people died
- 2 million people became displaced
(- In South East Asia, the tsunami killed more than 225,000 and displaced an estimated amount of 1.2 million??)
- A death toll of 186,983.
- 42,883 people went missing.
- 229,866 people were lost during the tsunami.
- People were swept away in the waters which arrived violently and without warning, everyone is frightened and terrified, the tusnami washing away loved ones.
- Family members die or are missing. Parents are lost somewhere in the waves or parents dying, leaving their kids traumatized at night, waking up from nightmares or even unable to fall asleep at night. The children are terrified, scared, crying, miserable and lonely. Not knowing what to do or how to survive without their parents.
- The tsunami effected some of the poorest people in Asia.
-
- Tree branches snapped off and broken
- Damage to building and infrastructure
- Broken houses, furniture and much more
- Short term aid for example water purification tablets, temporary housing and medical supplies were provided by countries around the world
-Washed away two thirds of their inhabitants
- Flooding which caused the water to be able to crumble the coastal structures.
Tsunami hit Indonesia first. After 45 minutes, the tsunami reached Thailand destroying everything.
Compared to the Pacific, the Indian Ocean did not have a warning system to alert residents living in the areas that a tsunami was approaching. When the tsunami struck, there was no warning apart from the sight of a large wave heading towards them, leaving them terrified, unprepared and parents shouting at their children to evacuate and find some kind of safety.
A tsunami is a series of ocean waves that sends surges of water, sometimes reaching heights of over 100 feet (30.5 meters), onto land. These walls of water can cause widespread destruction when they crash ashore.
These awe-inspiring waves are typically caused by large, undersea earthquakes at tectonic plate boundaries. When the ocean floor at a plate boundary rises or falls suddenly it displaces the water above it and launches the rolling waves that will become a tsunami.
