Earthquake and Tsunami
Tsunamis and earthquakes are both natural disasters arising out of the movement of the earth's tectonic plates. There are a number of risk-management plans in place that can help mitigate each disaster, but some, frankly, are more effective than others. The risk management of both earthquakes and tsunamis are entirely dependent upon the location and severity of the issue. For instance, Japan, which is prone to both, has built a number of tsunami walls designed to protect the shore from waves. They have also built floodgates and channels to redirect the water should it rise above the protection. Some countries plant vegetation like coconut palms or casurina to create a natural barrier, and studies have shown that mangrove forests and enhanced coral reefs can, if worked properly, reduce tsunami wave heights by about 80% (Tsunami Barriers). Both earthquakes and tsunamis can be mitigated by reforestation projects (tsunamis), but building using earthquake proof technology and materials that will "bend" or hold longer, and most particularly by setting up a warning system, by communicating effectively to the populace with an evaluation or preparedness plan, by having an infrastructure available to respond to the disaster, and then a wider range recovery plan. These last few issues are at the...
It was the most powerful earthquake to hit Japan, and one of the most five powerful earthquakes since 1900. The earthquake triggered tsunami waves that exceeded 130 feet, and travelled about 6 miles inland. The earthquake was so powerful, it moved Japan's main island of Honshu 8 feet east and shifted the Earth's axis by 4-10 inches (Buerk).
The aftermath of the earthquake was both a human and economic disaster. It displaced over 300,000 people, caused tremendous economic damage to the infrastructure of Japan through shortages of food, water, shelter, and fuel. In addition, the economic impact included the immediate costs (insurance, lack of resources, closed or damaged businesses, workforce issues) but also a $122 billion cost of rebuilding. Industrial production was suspended in many factories, and the transportation networks were so affected that many businesses that regularly shipped goods to Japan (Japanese and other imports) were curtailed during the crisis. Power shortages and damage hit the north-east coast of Japan causing a drop in overall production and…

In the past century, tsunamis have killed more than 50,000 people. Scientists have set the Pacific Tsunami Warning System in Hawaii in U.S.A to save lives. The system of earthquake detectors and tide gauges can sense quakes that may create a tsunami. We cannot conquer the tsunami, but we can know when it's approaching and run away from the sea monster's vehemence. (Killer wave! Tsunami) Tsunami in Indonesia: An earthquake measuring
Tsunamis A succinct definition of a tsunami is " ... A natural phenomenon consisting of a series of waves generated when water in a lake or the sea is rapidly displaced on a massive scale. ( Wikipedia: Tsunami) A more explicit and technical definition is, " A tsunami is a very long-wavelength wave of water that is generated by sudden displacement of the seafloor or disruption of any body of standing
Besides the deaths, more than one million people were left homeless and hundreds of thousands homes and businesses were destroyed. The United Nations estimated that, "...the disaster will prove to be the costliest ever recorded, with full economic recovery not expected for up to 10 years in many areas. " (Intute: Science, engineering and technology: Tsunamis) The physical structure of the coast and the environment was severely damaged which meant that
Earthquakes The major earthquake that struck offshore from Japan in March, 2011, was one of the largest earthquakes experienced in that region of the world in many years. It caused massive damage and it spawned a powerful tsunami that literally wiped many Japanese towns off the map. The causes of earthquakes are known to scientists, although science has not yet become sophisticated enough to predict when and where an earthquake will
Earthquakes Over the past 25 years, powerful earthquakes have struck different parts of the planet with alarming regularity. In this relatively short time span, there have been more than 30 earthquakes that have resulted in death tolls of more than 1000 people, with several of this disaster measuring over 7.0 on the Richter scale (U.S. Geological Survey, 2010). One of the biggest earthquakes in the last 25 years is the 2010
