Nuclear disasters set precedence for one of the most difficult disasters people may deal with. The duration of these disasters have lasting effects for generations and present an astronomical cost to man and the environment. Significant damage will persist from the nuclear disaster which occurred at the Nuclear Power Plant Fukushima Daiichi. With the nuclear revolution only in its infancy, our ability to cope with these incidents is limited to our experiences of the Three Mile Island reactor meltdown and the events in Chernobyl Ukraine. With so few instances of major nuclear disasters taking place, the Fukushima disaster presents many significant and exceptional challenges for Japan and the rest of the world. Several aspects unique to, but not limited to nuclear disasters are damage assessment, debris removal and media interaction with authorities throughout the emergency management process. On 11 March 2011 the Tohuku earthquake and subsequent tsunami struck the coast of Japan causing one of the most expensive disasters in human history. The earthquake is often referred to as the “Great East Japan Earthquake,” which measured 9.0-magnitude (Zhang 1). The tsunami, created by the earthquake sent powerful waves into the land mass of Japan, devastating many coastal areas. Recognized as one of the most powerful earthquakes to have been recorded in modern times, The Tohoku earthquake and related effects resulted in an estimated $235 billion in damages (Zhang 1). Located along the North-East coast of Japan, the Fukushima Daiichi Nuclear Power Plant, managed by Tokyo Electric Power Company (TEPCO), was one of the most distinct pieces of infrastructure damaged in the wake of the earthquake and tsunami.

Early in the morning of April 27, 1986, the world experienced its largest nuclear disaster ever (Gould 40). While violating safety protocol during a test, Reactor 4 at the Chernobyl power plant was placed in a severely unstable state, and in a matter of seconds the reactor output shot up to 120 times the rated output (Flavin 8). The resulting steam explosion tossed aside the reactor’s 1,000 ton concrete covering and released radioactive particles up to one and a half miles into the sky (Gould 38). The explosion and resulting fires caused 31 immediate deaths and over a thousand injuries, including radiation poisoning (Flavin 5). After the accident more than 135,000 people were evacuated from their Ukrainian homes, but the major fallout occurred outside of the Soviet Union’s borders. Smaller radioactive particles were carried in the atmosphere until they returned to earth via precipitation (Gould 43). The Soviets quickly seeded clouds to prevent rainfall over their own land, so most of the radioactivity burdened Western Europe, Scandinavia, and the Atlantic and Arctic Oceans (Flavin 12). This truly international disaster had far reaching effects; some of these were on health, the environment, social standards, and politics.
Chernobyl, one word that still strikes pain and fear in the hearts of many, even after 28 years is still causing serious damage. It was largest nuclear disaster ever, Chernobyl was “. . . about 400 times more potent than the bomb dropped on Hiroshima during World War II . . .” (Walmsley “26 years on: helping Chernobyl's children”). The disaster was not immediately seen as a large threat, and this is why so many lives were taken or destroyed.
TOHOKU, Japan, Friday, Mar. 11 -Yesterday, a 9.0 magnitude Earthquake struck the east of Tohoku, Japan. The epicentre of the earthquake was located approximately 72 km east of Tohoku (38.3 degrees North latitude and 142.4 degrees East longitude), or 130 km east of Sendai as shown by the X in figure 3 below. The focus of the earthquake was 24.4 km under the epicentre. The earthquake therefore caused a tsunami due to the displacing of water above the Pacific Plate. The earthquake and tsunami together have caused approximately 20,000 deaths, 6152 injuries and 2500 people missing. Approximately 90% of these deaths were by drowning. Approximately 140,000 people have been displaced and over 500,000 buildings and structures have been destroyed or damaged. The early warning system of Japan stopped many bullet trains, and many residents received texted warnings of the earthquake and tsunami on their mobile phones giving them time to evacuate. Figures 1 and 2 show exactly how destructive the tsunami caused by the Tohoku Earthquake was.

I. (Gain Attention and Interest): March 11, 2011. 2:45 pm. Operations at the Fukushima Daiichi Nuclear Power Plant continued as usual. At 2:46 pm a massive 9.0 earthquake strikes the island of Japan. All nuclear reactors on the island shut down automatically as a response to the earthquake. At Fukushima, emergency procedures are automatically enabled to shut down reactors and cool spent nuclear fuel before it melts-down in a catastrophic explosion. The situation seems under control, emergency diesel generators located in the basement of the plant activate and workers breathe a sigh of relief that the reactors are stabilizing. Then 41 minutes later at 3:27 pm the unthinkable occurs. As workers monitored the situation from within the plant, citizens from the adjacent town ran from the coastline as a 49 foot tsunami approached. The tsunami came swiftly and flooded the coastline situated Fukushima plant. Emergency generators were destroyed and cooling systems failed. Within hours, a chain of events led to an explosion of reactor 1 of the plant. One by one in the subsequent days reactors 2, and 3 suffered similar fates as explosions destroyed containment cases and the structures surrounding the reactors (Fukushima Accident). Intense amount...

Humans were a victims of the Chernobyl nuclear accident which affected their lifestyle and their health. People of Chernobyl were evacuated to clean and safe areas. According to the World Health Organization (WHO) (2006), there were 116 000 people who were evacuated from Chernobyl region to other safe areas in the summe...
Chernobyl was the greatest nuclear disaster of the 20th century. On April 26th, 1986, one of four nuclear reactors located in the Soviet Union melted down and contaminated a vast area of Eastern Europe. The meltdown, a result of human error, lapsed safety precautions, and lack of a containment vessel, was barely contained by dropping sand and releasing huge amounts of deadly radioactive isotopes into the atmosphere. The resulting contamination killed or injured hundreds of thousands of people and devastated the environment. The affects of this accident are still being felt today and will be felt for generations to come.
While the early warning saved thousands of people, the Japan’s Meteorological Agency underestimated this earthquake as the subduction zone of Japan should not produce the magnitude 9.0 quake (Oskin, 2013a). The Tohoku Earthquake and its tsunami approximately killed 16 thousand people, injured 6 thousand people and around 3 thousand people were missing. Most people died from drowning. Around 300 thousand buildings, 4000 roads, 78 bridges, and many more were affected by the earthquake, tsunami, and fires from leaking oils and gas. Electricity, telecommunication, and railways were severely damaged. The debris of 25 million tons was generated and carried out to the sea by water (BBC News, 2012). The country’s authorities estimated more than 309 billion US dollars of damages. Landslides occurred in Miyagi and liquefaction in Chiba, Tokyo, Odaiba, and Urayasu (USGS, 2013). Furthermore, the tsunami destroyed protective tsunami seawalls. Approximately 217 square miles of Japan covered in water (Oskin,
The energy industry is beginning to change. In today’s modern world, governments across the globe are shifting their focuses from traditional sources of power, like the burning coal and oil, to the more complex and scientific nuclear power supply. This relatively new system uses powerful fuel sources and produces little to no emissions while outputting enough energy to fulfill the world’s power needs (Community Science, n.d.). But while nuclear power seems to be a perfect energy source, no power production system is without faults, and nuclear reactors are no exception, with their flaws manifesting in the form of safety. Nuclear reactors employ complex systems involving pressure and heat. If any of these systems dysfunctions, the reactor can leak or even explode releasing tons of highly radioactive elements into the environment. Anyone who works at or near a nuclear reactor is constantly in danger of being exposed to a nuclear incident similar to the ones that occurred at the Chernobyl and Fukushima Daiichi plants. These major accidents along with the unresolved problems with the design and function of nuclear reactors, as well as the economic and health issues that nuclear reactors present serve to show that nuclear energy sources are not worth the service that they provide and are too dangerous to routinely use.
There was a multitude of causes of the disaster in Japan. The first cause was a 9.0 magnitude earthquake that occurred off the coast of Japan. Japan is located in “The Ring of Fire,” an area in the Pacific Ocean that has multiple faults and earthquakes (Pedersen 13). Tectonic plates shifted off the North Pacific coast of Japan and created a massive earthquake. The next cause was a thirty-three foot wall of water that swept over cities and farmland in Japan (Branigan 2). Martin Fackler, a journalist, stated, “The quake churned up a devastating tsunami” (Fackler 3). The tsunami reached speeds of 497 miles per hour while approaching Japan (Fackler 3). The third and final reason of the disaster was that the cooling systems at multiple nuclear power plants failed. At Fukushima, a nuclear power plant in Sendai, Japan, the radioactive rods began to overheat due to the absence of water, which cools it. Explosions occurred at three of the reactors, which spewed radiation into the air (“Comparing nuclear power plant crises”). In conclusion, the earthquake, tsunami, and nuclear power plant issues were the causes of the disaster in Japan, but they also had a myriad of effects.
