How did the Indian Ocean tsunami affect biodiversity?

There is no evidence that the conservation status of any Globally Threatened bird species has worsened as a result of this event. … Extensive areas of mangroves were destroyed or damaged by the tsunami, meaning that mangrove specialist birds will have lost a proportion of the habitat available to them.

How did the Indian Ocean tsunami affect the environment?

Most of the damage was to the coastal infrastructure, including harbours, destruction of coastal vegetation, and extensive sand erosion. Sea water intrusion into inland areas also affected soil fertility, causing many islands’ top soil to be washed away and increasing the salinity of the soil.

How do tsunamis affect biodiversity?

Tsunamis not only destroy human life, but have a devastating effect on insects, animals, plants, and natural resources. A tsunami changes the landscape. It uproots trees and plants and destroys animal habitats such as nesting sites for birds.

How did the Indian Ocean tsunami affect different countries?

The tsunami killed at least 225,000 people across a dozen countries, with Indonesia, Sri Lanka, India, Maldives, and Thailand sustaining massive damage. Indonesian officials estimated that the death toll there alone ultimately exceeded 200,000, particularly in northern Sumatra’s Aceh province.

Why was the Indian Ocean tsunami so disastrous?

The December 26, 2004 Indian Ocean tsunami was caused by an earthquake that is thought to have had the energy of 23,000 Hiroshima-type atomic bombs. … As a result, trillions of tons of rock moved, causing the largest magnitude earthquake in 40 years.

How could a tsunami affect a coastal ocean ecosystem?

Tsunamis scrape seafloor sediments and invertebrates, crash through coral reefs and destroy coastal vegetation. While ecosystems can recover, human interference may interfere.

How do tsunamis affect aquatic ecosystems?

Tsunami currents increase strongly in shallow water where weaker corals can be broken by the force of the tsunami. Fish and marine animals are sometimes stranded on the land after they are carried by the currents to shore. The currents also move sand from the beach onto nearby coral reefs, burying low lying corals.

How does a tsunami affect the atmosphere?

The high and low points of tsunami waves compress and extend the air above them, creating corresponding gravity waves in the atmosphere. These waves travel upward through the air, where they affect the density of the electrons in the upper atmosphere layer called the ionosphere.

How a tsunami wave changes as it approaches the coast?

As the tsunami waves become compressed near the coast, the wavelength is shortened and the wave energy is directed upward – thus increasing their heights considerably. Just as with ordinary surf, the energy of the tsunami waves must be contained in a smaller volume of water, so the waves grow in height.

How much did the 2004 tsunami cost?

How much financial damage did the 2004 tsunami cause? In terms of the death toll and the number of displaced people, this was the worst natural disaster in recorded history in Indonesia, Sri Lanka and Thailand. The total economic cost of damage was estimated at US$ 9.4 billion.
