[ A critical Analysis of Tohoku Earthquake an Tsunami , Japan] TOHOKU EARTHQUAKE AND TSUNAMI 2011 [JAPAN] Saurabh kumar MD2014DM024 EARTHQUAKE AND TSUNAMI TOHOKU, JAPAN 2011 Introduction Japan is one of the developed economies of the world .Basically Japan is one of the islands nations .It has long history of disaster. It has felt nuclear bombing as a major disaster in the year 1945 during the 3RD World war due to which a large chunk of its Population gets diseased due to the exposure to the radiation .It experiences frequent earthquake and tsunami due to its geographical location just because of it lies where Eurasian and pacific plates meet .If there is any disturbance in the techtonic plates then it is going to feel earthquake or tsunami …show more content…
Why did the Tohoku earthquake happened ....??????????? According to the scientists of international organisations it poses a question what made such a powerful earthquake possible ,and could it happen again in japan or somewhere else again. So, a group of international scientists drilled miles beneath the pacific ocean and found an interesting phenomenon The epicentre of the 2011 quake was in an the unusual spot ,about 130 kilometres east of Sendai ,Japan just off the northern coast of the nation .In this area a subduction zone the pacific plates driving beneath the Eurasian plates. Strong earthquake are possible here ,but scientists hadn’t thought that there was enough energy to produce one larger than magnitude 7.5.They were wrong ,and they,ve been interested in finding out more about what made the fault capable of producing such large earthquake. After some time they sent a drilling vessel Chikyu with the mission to drill into the fault
Activity of the Cascadia Fault is what had triggered the activity of St Helens in 1980 and in 2004. The Cascadia fault is a convergent plate boundary. The fault is a described as long and slopping, it starts in Northern Vancouver Island and expands down to Northern California. The Cascadia fault line separates the Juan de Fuca plate and the North American plate. Tectonic processes active in the Cascadia subduction zone region include accretion, subduction, deep earthquakes, and active volcanism of the Cascades.
On March 22, 2014 a 600 foot high hillside fell into the town of Oso, Washington. The total area consumed by the slide was 1,500 feet long, 4,400 feet wide and varied in depth from 30 to 70 feet deep – 49 homes and other buildings were destroyed, 13 people were seriously injured, and 44 people were killed (Department of Homeland Security 2015, p. 2). The slide itself moved “about 200 miles per hour, generating an estimated 10 million cubic yards of material covering approximately 318 acres” (Department of Homeland Security 2015, p. 2). According to eye-witness accounts it took mere seconds for the flood of debris to make its way down the hill. Other issues arose as a result of the mudslide, the river was dammed by the debris, which caused flooding
This investigation developed the first comprehensive post-earthquake investigations. This investigation was chaired by Andrew Lawson among other geologists. This report offers a comprehensive understanding about the fields of geology, geodesy and seismology. The report also revealed the magnitude of damage within San Francisco and evidence of similar earthquakes in the past.
According to John Claque, the motion is curling the edge of the North America plate upwards, much the same way a rug would buckle if you pushed on one edge. This creates a major strain on the fault line until eventually, the north America plate "elastically bounces back", causing the mega thrust and creating the tsunami".
Although the San Francisco Earthquake of 1906 and the Great Chicago Fire of 1871 were both horrific events that created huge destruction on the United States, they took a big toll in people’s lives in many different ways and encouraged them to take charge and rebuild back their hometowns that they loved. The San Francisco Earthquake commenced at five thirteen o’clock in the morning, with the epicenter offshore of San Francisco. The city carried more than 400,000 people during this event (Earthquake of 1906, 1). Most of the citizens who were present during the earthquake were all in bed asleep, but the early morning risers were able to witness the start of everything (The Great 1906, 5).
The Loma Prieta Earthquake has played a significant role in shaping the San Francisco Bay area. It has helped bring awareness to the potential dangers an earthquake could cause. On October 17, 1989, a 6.9 magnitude earthquake rattled along the San Andreas fault line through the San Francisco Bay area. It killed over 67 people and caused about 3,800 injuries. My father was a police officer in the city Salinas, which was directly affected by the quake.
However, peculiarities of the lithosphere of the city can scare the newcomer. The city of San Francisco is in a high seismic activity zone, as very close are faults the San - Andreas (along the San Francisco Peninsula) and Hayward (on the eastern side of the bay). Small tremors come here often enough, but twice throughout its history (1906 and 1989) the city suffered the earthquake damage. The territory of San Francisco is a difficult terrain, as it has about fifty hills.
Hiroshima There were many factors that led up to the events of the U.S. dropping the bomb. the war dragging on and causing our generals to be very quick to pull the trigger. Many think that we could have won the war without dropping little boy( this is the name of the bomb) that killed close to two hundred thousand people. Because we dropped the bomb japan has been affected and the population of japan has been affected.
There are a lot of unexpected thing happened to our life. The Valdivia earthquake and Alaskan earthquakes is the most strongest earthquakes that ever happen in the world and this earthquakes are giving both of the two country a very big impact to their population and economy, they also losing a lot of people, housed, money and a huge of the area that earthquakes happened got damage. By the way one of the American author, Thomas Sowell, had said that “All thing are the same except for the differences and different except for the similarities” and that it true however both of them are the top strongest earthquakes but they are some different and similarity between them. Valdivia earthquake and Alaska earthquake are happened in America.
The commencing shock registered a magnitude of 7.0 and was then shortly followed by two aftershocks of magnitudes 5.9 and 5.5. More aftershocks occurred in the subsequent days. Causes of the Disaster The earthquake was generated by contractional distortion along
These two plates push and shove each other causing small tremors throughout which can cause landslides,volcanic eruptions and once in a couple years, quakes with devastating results. The strongest earthquake recorded occurred in 1991 with a measure of 7.6 on the Richter scale. This earthquake left 4 dead and buildings as well as bridges and road were completely destroyed. If another Earthquake occurs, the coastal cities would be the most affected ones as they are closer to the plates.
2006 L’Aquila earthquake hit Italy, for example, judges have had to determine whether scientists and authorities were criminally responsible for failing to adequately assess L’Aquila’s risks and for providing false assurances. Beyond the basic tenuousness of putative objective assessments, systematizing frameworks often conceal subjective value judgments and preferences. Because “numerical estimates of risks, costs, and benefits are [rarely] impartial reflections of factual reality,” at numerous junctures of decision-making, simply employing “alternative assumptions, valuation techniques, discount rates, and other seemingly technical trappings” can dramatically alter normative assessments. The same considerations apply to evaluations of
The 2011 Tōhoku earthquake and tsunami caused an immensely colossal number of displaced people. The number of the evacuees, as of 26 January 2012, was 341,411. Some earthquake survivors died in the shelters or in the process of voidance. Many shelters struggled to aliment evacuees and were not medically sufficiently equipped. Quandaries in stabilizing the Fukushima I plant have hardened postures to nuclear potency.
Case study 1 earthquake:(LEDC) On September 19th 1985 Mexico city was struck with a deadly earthquake. This earthquake measured at a magnitude of 8.0 and killed about 25 thousand people 9.5 thousand official and the rest weren 't found, 30 thousand injured and many more left home less, about 3 thousand buildings where demolished and 100 thousand badly damaged. This event costed the Mexican government 3-4 billion dollars to repair and support their city and the government didn 't accept any help from foreign countries, the next day September 20 Mexico city was struck by an after shock and then the Mexican government announced that they would accept any food, heath care ….
The Tohoku Earthquake was the most powerful earthquake recorded to have hit Japan. The earthquake was a magnitude 9.0 off the coasts of Japan that occurred at 2:46pm on Friday 11 March 2011, which triggered a powerful tsunami that reached the height up to 10.4 meters. A Japanese National Police Agency reported 15,889 deaths, 6,152 injured, and 2,601 people missing, 127,290 buildings totally collapse, 272,788 buildings half collapse, and another 747,989 buildings partially damaged. The Tohoku earthquake and tsunami caused severe structural damage in northeastern Japan, including heavy damage to roads, railways and dams, not to mention fires in many areas. It was the toughest and the most difficult crisis in Japan after the World War 2 leaving
