Download file to see previous pages People who lost their lives were as many as 250 000 across the shores of the Indian ocean and millions of people were displaced from their homes and their livelihoods destroyed. Countries that were directly affected by the earthquake include Indonesia, Maldives, the Seychelles, Somalia, Sri Lanka, Thailand and Yemen. The livelihoods of people were greatly affected especially the poor people who depended on the ecosystem and natural resources for survival. People lost their food stores and the shops in the coastline were greatly affected. Impact on environment/pollution Environmental impact assessment showed that there are great damages to both human and natural resources. The damage could have been larger but the natural resources also provided a first line defense to the tsunami effects. The damage needed an environmental reconstruction programme that cleaned the hotspots, carried the rehabilitation of the livelihoods and ecosystem, and strengthens environmental policies. The water and soils within the periphery of the coastal systems were greatly contaminated thus interfering with the coastal ecosystems (Samarajiva 14). Inland waters, wetlands, and agricultural lands that support people with food were greatly salinated thus affecting the agricultural yields. Shallow wells and ground water supplies in the small islands and in the coastal lands were greatly affected since their fresh waters were also salinized with the waters that overflowed from the ocean. About 90% of the toilets on the badly affected highlands and coastal regions lost and the waters contaminated with sewage. The living conditions were greatly affected since the survivors stood great chances of contaminating water borne diseases. In Sri Lanka; more than 25% of the wells become contaminated when the waters from the saline Indian Ocean and sewerage treatment systems mixed with them (UNEP 15). Waterborne diseases and vector borne diseases increased considerably resulting to high mortality rates along affected coastlines. The environmental infrastructure like water and sanitation systems together with disposal sites were tampered and greatly damaged. Contamination from waste deposits caused health and environmental problems that threatened livelihoods for several years. Most lives were saved due to the enormous humanitarian response that was quickly mobilized across the globe with appropriate mitigation measures put in place to improve environmental standards (Dawson & Stewart 17). Production of goods and services/Economic impact The economic activities in the coastline and the coastal highlands were greatly affected by the tsunami. Sources of daily income and food were totally destabilized leaving people vulnerable to hunger and thirst. Many of the victims were involved in fisheries prior to the attack but they are left with no source of income since their boats were destroyed and the aquatic system destabilized. Mangrove systems and the aquaculture provided a sustainable balance in the coastal systems that were greatly interfered with in the course of mangrove attack (UNEP 19). Rice crops in islands were seen to be yellowing in the field few weeks after the deadly tsunami, an indication that they were drying out. Soil conditions doubled their salt content needed by plants ...Download file to see next pages Read More

Tsunami Analysis

... tsunami. For instance, the article explores the displacement of over 458 households in the district of Aceh in Indonesia. The 2004 Asian tsunami caused a lot of damage and led to the loss of lives and livelihoods for a period of 3 months. Many people also died as a result of disease outbreaks in several regions after the tsunami. An earthquake with a magnitude of 9.0 occurred undersea off the coast of Sumatra led to the tsunami that caused a lot of damage. The tsunami did not spear the environment since several coastlands where the coastlines were redrawn leading to change in coastlines. For instance, the Andaman and Nicobar islands were severely destroyed by the Asian tsunami (Jayasuriya, 2010). Sea creatures were not speared...

Japan Tsunami

... earthquake but the current earthquake broke all the previous records on the Richter scale. The earthquake spread on a large area of 1,300 miles and it shook large cities miles away from the epicenter. The epicenter of the earthquake was said to be in Miyagi Prefecture which is about 230 miles away from Tokyo (Widespread destruction from Japan earthquake, tsunamis 2011).The intensity of the earthquake was such that one employee in Tokyo was stated as saying “It felt like the whole structure was collapsing” (Foster 2011). The tsunami had caused widespread chaos and had halted several services being operated within Japan. Electricity was lost in almost 10% of the households in Japan. The official figures of the people dead in Sendai...

Earthquake and tsunami in Japan

...of the paper will also take a look at other uses water could be put to. Earthquakes and Tsunamis are two of the worst devastating natural occurrences that could befall a nation or a region. The Japanese archipelago (which is a large group of Islands) is located in an area where several continental and oceanic plates meet. This is the cause of many earthquakes in Japan, (1). Earthquakes that occur below or close to the ocean may trigger tsunamis (which are tidal waves). Because of the radioactive leak from the damaged nuclear reactors, an estimated 200,000 residents in the area have been evacuated, according to the International Atomic Energy Agency. Iodine was also being distributed to those affected by...

The 21st Century Tsunami

...ay, the battle rages between contentment versus consumerism, freedom versus slavery and happiness against gloom. For many decades, developed countries have been unable to control their consumption rates. Unfortunately, the developing countries have also begun to follow the same destructive steps that create more worry and devastation at the expense of environment, happiness and human health. The result is a world filled with suffering. Consumerism has evolved to a Tsunami, sweeping the world away. The question in waiting is; Is the world suffering from consumerism? The increased rate in consumption poses a great threat to the meager resources in the world. Increased appetite depletes the natural resources with the exchange of non...

Tsunami: Definition And Prevention

... has been great. An estimated 245,000 people are in evacuation shelters; 243,000 homes are without power; and 720,000 homes without potable water. (Nanto, Cooper and Donnelly 5). The disastrous natural calamity that commonly hits Japan shows up when “a large volume of the ocean is quickly displaced, it will sometimes create a huge wave,” (Jeffrey 4). The source of tsunami is an underground earthquake usually from the ocean floor that can travel great distances and once the waves reach the coastline, it produces a giant wave called as “harbor wave.” The term was coined by the fishermen who experienced the surging waves. They found out later on when they returned to their harbor villages already destroyed by the waves (Spilsbury...

(Geology) Tsunami Threat in California

... Ocean Tsunami was one of the deadliest disasters that killed over 230,000 people in 14 countries near the Indian Ocean. Although researchers have identified the causes and other characteristics of this natural disaster, many facts about Tsunami still remain undiscovered. This paper will discuss the “Tsunami threat in California” in detail. Strike slip faults and dip slip faults Geological surveys have identified that most of the faults in the United States, specifically in California, are strike slip faults. In addition, the presence of dip slip faults also has been discovered in California (State of California, 1992). In geology, a fault indicates a discontinuity in a large volume of rock and this discontinuity or planar fracture often...

Indian Ocean Tsunami

..., cautionary system and safe places. Construction of physical barriers or dykes around the sea could have greatly reduced the effects of tsunami. Mitigation approaches could also have been applied to correct the situation. Such measures involve analysis of possible destructions from other similar occurrences. Such measures would also involve an analysis of seismic triggers to establish areas prone to an earthquake. Communication between the authority, seismologists, and the society could have helped to improve the situation as well. Such communication would be followed by recommendations and possible correction measures for any possible occurrence. Authorities in the affected areas could also have applied early warnings to the people...

... known as “run-up”. This phenomenon is very many feet high and its variation depends on the strength of striking waves (NOAA, 2009). Normal run-up height is about 30 meters high although there are some extra high run-ups such as that witnessed in Alaska in 1958 which went up to 60 meters high. Run-up rush onto the sea shore and strikes the coastal areas with an intensive, destructive force. Huge earthquakes are able to send tsunami waves across oceans. For instance, recent earthquakes in both Japan and Chile send tsunami waves which struck Alaska, Hawaii, Oregon, California, and Washington causing enormous losses of life and property. Water masses subjected to tsunami waves can take hours to regain stability hence tsunami effects can...

Emergency Risk Management: Tsunami as a Natural Disaster

... the above steps cannot escape the management from the residual risk, which remains and planning to manage the affects of residual risk has to be made. Treatment of risks comes in the last. It requires first of all identifying the choices. Next in line is the evaluation and selection of right options. After selecting the right options, treatment planning has to be prepared to finally implement it (Hodges, 2000). The process of disaster management stated above can be reexamined by knowing the disaster, its origin, its occurrence and how Tsunamis reach the land. How are Tsunamis generated? Tsunamis are generated when the water gets displaced at the bottom of the sea due to tectonic earthquake; it displaces the water. Waves get generated...

Disaster Management: Tsunami

...ext for its analysis. It is important to test the criteria to measure the risk and decide its body structure or elements to be followed on by analysis. Context should be found out at the beginning to build the body structure to accomplish risk analysis. For this, a complete evaluation of the environment and related policies, mission of the organisation is mandatory to know the practical aspects of risk management (Hodges, 2000). In the context of disaster or risk management, it is first of all important to know about the risk, and then its strategic management becomes fit for analysis, as it is not the work of a single organisation to manage a disaster like Tsunami. For this we need to know what a Tsunami is, causes and impacts of...

Nonetheless, when the tsunami (a rare and larger one) happened, it caused floods to the diesel generators and made them to fail (TEPCO press release (2011). A fundamental aspect of all nuclear power plant structure is “defense in depth.” This aspect results in engineers designing nuclear plants that can resist harsh disasters, even in case of various systems failing. A big tsunami that damages all diesel generators at the same time is also anticipated; however the tsunami that happened that day was not expected at all. Upon the failure of diesel generators, the operators switched on emergency battery powers. However the battery power was...

The Effects of the Tsunami in Japan

... on March 11, 2011 by a 9.0 magnitude earthquake. The huge tsunami destroyed a large number of many physical properties and many lives of Japanese citizens were lost. It caused damage to Japan’s economy because the economy is connected with other nations internationally from trade in goods and services (Steiner). The tsunami’s destruction of properties affected the main sources of Japan’s exports, and if it cannot export, then the economy is in jeopardy (Ferris & Solis). Therefore, it shows that tsunami had a negative effect on basis of cost of damage, stock market, Gross Domestic Product or output, power, currency, loss of lives, and food exports. Body Before tsunami occurred, Japan was the third largest country with respect to increase...
