The Japanese earthquake and tsunami of 2011 has been officially named by the Japan Meteorological Agency said the earthquake the Pacific coast of the Tohoku region 2011.
The earthquake of magnitude 9.0 on the Richter scale, caused a tidal wave or tsunami of up to 10 meters. The epicenter of the earthquake stood in the sea off the coast of Honshu, 130 km east of Sendai, in Miyagi Prefecture, Japan.
occurred due to a shift in the area near the interface between subducting plate between the Pacific Plate and the North American Plate . At the latitude where the earthquake occurred, the Pacific plate moves westward over the North American plate at a speed of 83 mm / year. The Pacific plate moves under Japan in the Japan Trench and sinks beneath west Asia.
The earthquake was the strongest Japan has suffered to date and fifth in the world.
Valdivia (Chile)
The most powerful earthquake ever recorded hit Chile on 22 May 1960, with a magnitude of 9.5 degrees on the Richter scale. It was the largest earthquake in the world, perceived in all the Southern Cone of America. 1,655 people were killed and 3,000 wounded, and 2,000,000 homeless. The tsunami that was generated after the quake caused serious damage in Hawaii, Japan, New Zealand, the Philippines and the United States.
Alaska (USA)
On March 27, 1964, Good Friday, a magnitude 9.2 earthquake hit Alaska. Also caused high tsunami, with waves that reached more than 5 meters. With a duration of 4 minutes, the "great Alaskan earthquake," as it's known, is considered the most powerful earthquake recorded in American history. Later estimates put at 200,000 square kilometers of the surface crust was deformed as a result of the earthquake. In addition, a major side effect of the shock was the change temportal soil and sand from solid to liquid as the hills Turnagain areas where the clay cliffs collapsed, taking with it homes.
Sumatra-Andaman
(Indonesia)
In 2004, an earthquake of 9.1 degrees in the Indian Ocean, with its epicenter near the west coast of Sumatra (Indonesia). Fourteen countries in South Asia and Africa were affected. Nearly 228,000 people dead or missing due to the earthquake. Is the longest of all has been made so far: between 8.3 and 10 minutes. And it was big enough to make the entire planet to vibrate at least one inch.
Kamchatka (Russia)
On November 4, 1952, a 9.0 magnitude earthquake hit Kamchatka, Siberia, and Kuril Islands, causing devastating tsunamis that hit Hawaii, Japan, Alaska, Chile and New Zealand. Tsunamis triggered reached Hawaii, Japan, Alaska, Chile and New Zealand.
Tohoku (Japan)
On March 11, 2011, lasted two minutes. NASA using satellite images has found that the quake may have moved Japan more than 2 meters. Several infrastructures have been severely affected by the earthquake, including four nuclear plants.
Side effects:
Japan widens
To calculate the displacement experienced by the island, experts Service United States Geological Survey (USGS) analyzed data from global positioning system (GPS). They have found that the nearest GPS stations the epicenter of the earthquake was moved up to four meters eastward. According to the USGS, the change occurred mostly in areas near the epicenter, while more distant stations showed much less movement. Geophysicist Ross Stein says that as a result, "Japan is wider than it was before."
According to NASA, the speed of rotation of the Earth has also been disrupted by the earthquake. Initial calculations show that day length was reduced by 1.8 microseconds (millionths of a second). This timescale is imperceptible to humans, but can be detected by satellites.
Broken Arrow
Four workers were injured in the blast, and have been transfers to a local hospital, sources said Tokyo Electric Power (TEPCO) the company that operates the plant, which has not yet information about their status. After the level of radioactivity recorded in the control room of a nuclear reactor in Fukushima I is a thousand times higher than normal, nuclear plant operators had successfully managed to release pressure from the number 1 reactor of the plant, given the high risk of existing nuclear fission. People living within a radius of ten kilometers from the plant were evacuated.
Economic Crisis
Experts estimate that Japan's reconstruction will cost about 180,000 million dollars or, which is the same, 3% of the country's current economic output. Will benefit the infrastructure associated with raw materials, whose prices may rise in 2012.
Despite the punishment that raw materials are suffering on the stock exchange next year is forecast that demand will grow by rebuilding infrastructure Nipponese. Worse
utilities will stop. Worldwide Air consultancy located between 15,000 and 35,000 million dollar losses in the sector.
Other sources of energy like oil, natural gas or coal are the face of the coin. According to analysts quoted by Barclays elconfidencial to replace the current reactors would require an increase of 7,800 tons per day of coal, 143,000 barrels of fuel, 67,000 oil and 800 million cubic feet of natural gas.
After the Kobe earthquake in 1995, Japan took just under five years to recover. The country has the resources and social cohesion needed to make the process faster. The drop in production can be offset by demand for reconstruction.
