Indian Ocean

The Indian Ocean is the third largest body of water in the world, covering approximately 20% of the Earth’s water surface. It has a total area of 73,556,000 square kilometers (28,350,000 square miles).

Why did the Indian ocean tsunami of 2004 take so many lives?

-500 kilometre wave wrecked havoc throughout the area

-struck at 8am meaning many were still asleep

-building quality not strong enough

-no medication

-water born diseases

-no early warning system

Do ocean currents change directions when weather affects it?

Actually, ocean currents are what largely regulate the weather and the wind. Currently, the North Atlantic current is warm, therefore a small area of Greenland and the Arctic are warming and causing a little more melting of glaciers in that area.

Where was the Indian Ocean tsunami located?

The Indian Ocean tsunami impacted almost every country around the Indian Ocean. Worst hit were Indonesia, Thailand, India, and Sri Lanka, but there was damage as far away as Madagascar and Mozambique.

Were they prepared for the tsunami Indian ocean?

No, many countries were not adequately prepared for the Indian Ocean tsunami in 2004. Early warning systems and disaster response plans were lacking in the region, leading to significant loss of life and destruction. Since then, efforts have been made to improve preparedness and response to future tsunamis.

Is the mid ocean ridge the location of the oldest ocean floor?

No, the mid-ocean ridge is actually where new oceanic crust is formed through volcanic activity. As the crust moves away from the ridge, it becomes older. The oldest oceanic crust is found near the edges of the ocean basins.

How fast was the 2004 Indian Ocean tsunami when it hit land?

When the waves first spread out from the earthquake's epicentre, they travelled at up to 800 kilometers per hour (500 mph). As tsunami waves approach the shore, their speed decreases, so by the time the 2004 tsunami reached land, the waves weren't going much faster than normal waves. They were travelling at about 1 kilometer per minute, which is about 60 kph or 37 mph. The subsequent force, together with the height and speed of the wave and the volume of water in it caused the damage to the land. Then when that same water retreated it sucked many people out to sea where many of them drowned.

How many aftershocks did the 2004 Indian Ocean earthquake cause?

The 2004 Indian Ocean earthquake resulted in thousands of aftershocks. Some sources estimate there were over 50,000 aftershocks following the main earthquake, with magnitudes ranging from 4.0 to 7.3.

Will the Indian Ocean tsunami happen again?

Not from the current location. The ocean floor shift had been building pressure for many years.

However, there will probably be another tsunami in the Indian Ocean eventually - there is no way of knowing when. When it does occur it will be a different tsunami from the one that occurred in 2004.

What was the speed of the Indian ocean tsunami?

Tsunamis will sometimes go undetected until they draw near shallow waters along a coast. Tsunamis are recurrent in Japan. Approximately 195 events have been recorded. Due to the immense volumes of water and energy involved, tsunamis can devastate coastal regions. Casualties can be high because the waves move faster than humans can run. These waves have outsized wave length (up to several hundred miles) that is a function of the depth of the water where they were formed. Although these waves have a small height, there is a tremendous amount of energy linked with them. As an effect of this huge amount of energy, these waves can become gigantic as they approach shallow water. As they crash upon the shore there height depends on the underwater surface features.

They can reach up to 100 to 300 feet. The world's largest tsunami ever recorded was in Lituya Bay, Alaska on July 9, 1958. The waves reached up to the height of 1,638 to 1,720 feet high. It was triggered by a landslide and an earthquake with a magnitude of 8.3.

Which is bigger the Atlantic Ocean or the Southern Ocean?

The Southern Ocean is 7.848 million square miles in size. The Southern Ocean is located at the bottom of Earth and surrounds Antarctica.

How were people affected by the 2004 Indian Ocean earthquake?

The 2004 Indian Ocean earthquake resulted in massive destruction, affecting several countries including Indonesia, Sri Lanka, India, and Thailand. Hundreds of thousands of people lost their lives, and many more were left displaced or injured. The disaster also caused widespread economic and infrastructural damage in the region.

Which states got hit by the tsunami the great Indian Ocean tsunami of 2004?

The 2004 Indian Ocean earthquake was an undersea megathrust earthquake that occurred at Sunday, 26 December 2004. The earthquake was caused by subduction and triggered a series of devastating tsunamis along the coasts of most landmasses bordering the Indian Ocean, killing over 230,000 people in fourteen countries, and inundating coastal communities with waves up to 30 meters (98 ft) high. It was one of the deadliest natural disasters in recorded history.

How did the Sumatra-Andaman earthquake cause so much damage if it occurred in the middle of the Indian Ocean?

Most of the damage from the Sumatra-Andaman earthquake was from the tsunami it triggered rather than the earthquake itself. When the earthquake occurred it caused the seafloor to shift upwards, displacing an enormous column of water. This caused a wave to race across the ocean that came ashore in many locations as a surge of water with enough force to sweep away entire buildings.

How many people can one tsunami wave kill?

The number of people a tsunami wave can kill depends on many factors, such as the wave's height, speed, and the population density of the area it hits. In major tsunamis, thousands of people have been killed, while smaller events may result in fewer casualties. Early warning systems and evacuation procedures can help reduce the death toll.

Does seaweed live in rivers?

Seaweed typically lives in saltwater habitats like oceans and seas. While some freshwater species of algae, which may resemble seaweed, can be found in rivers, true seaweed is not commonly found in river environments.

What causes the golden haze over the Indian Ocean?

The golden haze over the Indian Ocean is typically caused by the scattering of sunlight by particles in the atmosphere such as dust, pollution, or sea spray. This scattering effect gives the sky a golden hue during sunrise or sunset, especially in areas with high humidity.

How does the animal and plant life contribute to the Indian Ocean?

Animal and plant life in the Indian Ocean play a crucial role in maintaining the overall health of the marine ecosystem. They help to regulate the food chain, recycle nutrients, and provide habitats for other species. Some species also support local economies through fishing and tourism activities.

Which island in the Indian Ocean is crossed by the Tropic of Capricorn?

What is the depth of the continental slope in the Indian ocean?

The depth of the continental slope in the Indian Ocean can vary, but on average it ranges from about 600 to 6,000 feet (180 to 1,800 meters). This steeply sloping region connects the continental shelf to the deep ocean floor of the abyssal plain.

What is the quickest way to get by ship from the mediterranean sea to the indian ocean?

The quickest way to travel by ship from the Mediterranean Sea to the Indian Ocean is through the Suez Canal. This man-made canal in Egypt connects the Mediterranean Sea to the Red Sea, providing a shortcut for ships traveling between Europe and Asia. The journey through the Suez Canal helps ships avoid the longer route around the southern tip of Africa.
