What to Do? What are the factors of destruction from tsunamis? Available in English and Samoan. The water can be just as dangerous, if not more so, as it returns to the sea, taking debris and people with it. The debris in the water is particularly dangerous as evidenced by bruises on the bodies of many victims of the Indian Ocean tsunami.
In addition to loss of life and mass injuries, other potential impacts include damage to and destruction of homes and businesses, ports and harbors, cultural resources, utilities, and critical infrastructure and facilities. There may be loss of access to basic services such as power, sewer, and water. Communications, transportation ground, air, and marine , and health and public safety services may be disrupted.
Impacts from a large local tsunami will likely be in addition to impacts from a preceding earthquake, and impacts from both may trigger secondary hazards, which could be more devastating than the direct destruction.
Earthquakes and tsunamis can cause fires, transportation accidents, and hazardous material releases into the environment, contaminating water supplies and threatening public health. These impacts can further complicate evacuation, response, and recovery. Governments around the world may help with the cost of bringing aid to devastated areas. National institutions, the United Nations, other international organizations, community groups and NGOs , and a variety of other entities come together to provide different kinds of aid and services.
There might also be appeals and donations from people who have seen pictures of the area in the media. Reconstruction and clean up after a tsunami is a huge cost problem. Infrastructure must be replaced, unsafe buildings demolished and rubbish cleared.
Loss of income in the local economy and future losses from the destruction of infrastructure will be a problem for some time to come. The total financial cost of the tsunami could be millions or even billions of dollars of damage to coastal structures and habitats. It is difficult to put an exact figure on the monetary cost but the cost may represent an important share of a nation's GDP. Victims of tsunami events often suffer psychological problems which can last for days, years or an entire lifetime.
These people were suffering from grief and depression as their homes, businesses and loved ones were taken from them. Many still had PTSD. Periliya Village counts 2, dead and families became homeless. These people were found to still have psychological problems 2 years after the tsunami. Tsunamis: the effects Introduction The effects of a tsunami on a coastline can range from unnoticeable to devastating.

The indiscriminate conversion of natural shorelines and mangrove forest ecosystems for shrimp farming, urban settlements, tourism development and other often unregulated and unplanned human activities over the past several decades often make the coastal areas and its inhabitants much more vulnerable to the immense destructive force of the tsunamis.
The need for a global effort to prevent and predict tsunamis has been widely articulated after the disaster. The article 'Tsunami Warning Systems' presents a brief overview of different warning systems and the international effort to set up a warning system across the globe. For an update on the efforts at another level, visit the official site of the World Meteorological Organisation.
Natural barriers against tsunamis: coral reefs and mangroves Apart from technology, we can also use natural barriers to protect us from natural disasters. Coral reefs act as natural breakwaters, providing a physical barrier that reduces the force of a wave before it reaches the shore, while mangrove forests act as natural shock absorbers, also soaking up destructive wave energy and buffering against coastal erosion.
