How was the environment affected by the 2004 tsunami?

How was the environment affected by the 2004 tsunami?

The tsunami’s medium-long term effects on the environment include potential damage to coral reefs, loss of fertile soil, loss and degradation of vegetation (including e.g. mangroves and sea grass), and salt intrusion into soil and inland water.

How did the 2004 tsunami affect agriculture?

The Food and Agricultural Organization (FAO) reported that the tsunami affected significant agricultural land, destroyed irrigation canals, affected 92,000 farms, displaced 60,000 farmers and robbed 330,000 people of their livelihoods in fishing and agriculture in the province.

What were the environmental effects of the Boxing Day tsunami?

There were some environmental impact as an aftermath of the tsunami. In the affected region, crops were destroyed and farm land was ruined by the salt water. Many forest and trees such as mangrove forests along the coast were also destroyed. Coral reefs and coastal wetlands were damaged.

How do tsunamis affect estuaries?

As the tsunami bore reaches the bay mouth, the flow speed increases and scours the floor of bay. Inland of the mouth, the channel widens, causing flow to slow down, allowing sediment to settle out of the water column.

How does a tsunami affect the hydrosphere?

A tsunami creates a surge of ocean water that can sometimes engulf large geographic areas. As the ocean water comes ashore, drinking water wells can become submerged and potentially contaminated with microorganisms (bacteria, viruses, parasites) and chemicals that can adversely affect human health.

Why was the 2004 tsunami so destructive?

The violent movement of the Earth’s tectonic plates displaced an enormous amount of water, sending powerful shock waves in every direction. The tectonic plates in this area had been pushing against each other and building pressure for thousands of years.

What was the response to the 2004 tsunami?

The aid response to the 2004 Indian Ocean tsunami was unprecedented for a natural disaster, with a colossal $6.25bn donated to a central UN relief fund assisting 14 countries. The series of tsunamis on 26 December 10 years ago killed more than 228,000 people and left more than 2 million people homeless.

How do tsunamis affect landscapes?

Environmental impacts A tsunami changes the landscape. It uproots trees and plants and destroys animal habitats such as nesting sites for birds. Land animals are killed by drowning and sea animals are killed by pollution if dangerous chemicals are washed away into the sea, thus poisoning the marine life.

How do tsunamis affect coastlines?

Upon making contact with the shore, tsunamis can severely alter the coastal landscape through rapid erosion and deposition of sediment. High wave energy may transport coastal vegetation and marine debris and leave in place unstable barren dunes susceptible to further erosion.

How did the 2004 tsunami affect the hydrosphere?

Is a tsunami in the hydrosphere?

Tsunamis are giant waves in the ocean (hydrosphere), triggered by earthquakes (a primary force in the lithosphere), and have deadly consequences on coastal communities (the biosphere).
