Japan Tsunami : 

J apan T sunami Japan Tsunami

PowerPoint Presentation: 

Japan was hit by a 9.0 magnitude earthquake on March 11, 2011, that triggered a deadly 23-foot tsunami in the country's north. The giant waves deluged cities and rural areas alike, sweeping away cars, homes, buildings, a train, and boats, leaving a path of death and devastation in its wake. The earthquake—the largest in Japan's history—struck about 230 miles northeast of Tokyo. According to the official toll, the disasters left 15,839 dead and 3,647 missing.

On March 11, 2011, a magnitude 8.9-9 megathrust earthquake off the north eastern coast of Japan triggered a large tsunami, with wave heights reaching up to 10m. These two events caused widespread devastation and destruction in Japan, including washing away entire cities as well as damaging the country's nuclear power plants, thus causing potential meltdowns

In light of Friday's tsunami following the Japan earthquake , find out how the killer waves are caused, what the warning signs are, and how to respond when a tsunami threatens. A huge tsunami spawned by the magnitude-8.9 quake—one of the largest ever recorded—rocked Japan's eastern coast, killing hundreds of people, according to the Associated Press :

Radiation :- Damage to the Fukushima Dai-ichi nuclear power plant after the earthquake and tsunami resulted in a leak of radioactive material from this facility. At this time, the risk of contamination from radioactive materials and the risk of exposure to radiation are thought to be low, especially for anyone staying at least 50 miles from the nuclear power plant.:

On March 11 2011, an earthquake at 9 on the Richter scale became the biggest earthquake in recorded history to hit Japan (and the fifth biggest in the world). Japan’s main island moved 2.5 meters and the earth’s axis moved 10 cm. There have been hundreds of aftershocks since (5 ranging from 6 to 6.2, the biggest a massive 7.1 on April 7 and 6.6 on April 11 2011.). THE TSUNAMI Tsunami wave was as high as 15 meters (North-Eastern Japan) and travelled as far as 10km inland. The worst hit was Kamaichi and the port town of Sendai as well as the nearest islands. At top speed, the tsunami travelled at 800km per hour.

Energy This earthquake released a surface energy of 1.9 ± 0.5×1017 joules, dissipated as shaking and tsunamic energy, which is nearly double that of the 9.1-magnitude 2004 Indian Ocean earthquake and tsunami that killed 230,000 people. If harnessed, the surface energy from this earthquake would power a city the size of Los Angeles for an entire year] The total energy released, also known as the seismic moment (M0), was more than 200,000 times the surface energy and was calculated by theUSGS at 3.9×1022 joulesslightly less than the 2004 Indian Ocean quake. This is equivalent to 9,320 gigatons of TNT, or approximately 600 million times the energy of the Hiroshima bomb. Japan's National Research Institute for Earth Science and Disaster Prevention (NIED) calculated a peak ground acceleration of 2.99 g (29.33 m/s²) The largest individual recording in Japan was 2.7g, in the Miyagi Prefecture, 75 km from the epicentre; the highest reading in the Tokyo metropolitan area was 0.16g:

The earthquake which was caused by 5 to 8 meters upthrust on a 180-km wide seabed at 60 km offshore from the east coast of Tōhoku resulted in a major tsunami which brought destruction along the Pacific coastline of Japan's northern islands and resulted in the loss of thousands of lives and devastated entire towns. Chile's section oPacific coast is one of the furthest from Japan, at about 17,000 km (11,000 mi) awaybut still was struck by tsunami waves 2 m (6.6 ft) high A wave height of 38.9 meters (128 ft) was estimated at Omoe peninsula, Miyako city, Iwate prefecture:

Japan experienced over 900 aftershocks since the earthquake, with about 60 registering over magnitude 6.0 M w and at least three over 7.0 M w . A magnitude 7.7 M w and a 7.9 M w quake occurred on 11 Marchand the third one struck offshore on 7 April with a disputed magnitude. Its epicenter was underwater, 66 km (41 mi) off the coast of Sendai. The Japan Meteorological Agency assigned a magnitude of 7.4 M JMA , while the U.S. Geological Survey lowered it to 7.1 M w . At least four people were killed, and electricity was cut off across much of northern Japan including the loss of external power to Higashidori Nuclear Power Plant and Rokkasho Reprocessing Plant Four days later on 11 April, another strong magnitude 6.6 M w aftershock struck Fukushima, causing additional damage and killing a total of three people .

PowerPoint Presentation: 

The Fukushima I, Fukushima II, Onagawa Nuclear Power Plant and Tokai nuclear power stations, consisting of a total eleven reactors , were automatically shut The 7 April aftershock caused the loss of external power to Rokkasho Reprocessing Plant and Higashidori Nuclear Power Plant but backup generators were functional. Onagawa Nuclear Power Plant lost 3 of 4 external power lines and lost cooling function for as much as 80 minutes. A spill of a couple liters of radioactive water occurred at Onagawa .

Telecommunications Cellular and landline phone service suffered major disruptions in the affected area. On the day of the quake, American broadcaster NPR was unable to reach anyone in Sendai with working phone or Internet. Internet services were largely unaffected in areas where basic infrastructure remained, despite the earthquake having damaged portions of several undersea cable systems landing in the affected regions; these systems were able to reroute around affected segments onto redundant links.

Now Japan has recovered through this disaster event and continues with its flourishing and amazing technology.
