Japan, a world leader in earthquake engineering, has been paralyzed by a series of giant waves that followed one of the most violent earthquakes in a century. Residents of the port town of Kamaishi in Iwate prefecture watch in horror as the first huge tsunami waves sweep away cars and buildings.
The news recalls the estimated 250,000 people who perished, mainly on the Indonesian island of Sumatra, in the 2004 “Christmas tsunami” that followed a huge, offshore quake.
Shortly after Japan stopped shaking at 2:46 pm local time on Friday, March 11, we began hearing about troubles at a series of nuclear plants. With the first nuclear meltdowns since Chernobyl, in 1986, under way, global stock markets were crashing. A helicopter flies over the city of Sendai, as it delivers more than 1,500 pounds of food donated by citizens of Ebina City, Japan, to survivors of the earthquake and tsunami. Although landslides and volcanoes cause some tsunamis, probably 95 percent result from underwater earthquakes that contain a strong vertical motion.
Like the Sunda trench near Sumatra, the subduction zone in the Japan trench is notorious for large earthquakes, says Timothy Masterlark, an associate professor of geological science at the University of Alabama.
Masterlark, who has studied the giant, 2004 earthquake and tsunami in Sumatra, says the magnitude 9.0 earthquake in Japan likely broke a fault stretching at a shallow angle from the sea floor roughly 150 kilometers beneath Japan, along a trench several hundred kilometers in length.
We asked Masterlark how, if the slip was mainly horizontal, the rocks had enough vertical movement to cause a tsunami.
To imagine how vertical movement of the seafloor causes a tsunami, imagine making waves by throwing a stone in a pond. The tsunami is usually most intense close to the earthquake: as waves spread from the epicenter in a typical arc-shaped pattern, their energy also spreads out.
One factor that distinguishes tsunamis from more familiar waves is their extreme wavelength. In some earthquakes, the biggest killer is not the shaking, but the walls of water created by undersea earth movement.
All that kinetic energy can hide in waves we can barely see because long-wavelength waves are extremely deep, and the massive amount of water moving beneath the surface contains enormous energy.
Like all waves, tsunamis slow when the lower part of the wave encounters the upward-sloping ocean floor. In 1998, Harry Yeh, a civil engineering professor now at the University of Oregon, told us that tsunamis can have decidedly unconventional behavior.
A series of massive earthquakes levels Lisbon during the celebration of All Saints’ Day. Krakatau, a volcano in the Sunda Straits, explodes with a gigantic roar audible 3,000 miles away. The Sanriku tsunami starts, as many do, when the sea withdraws with a great sucking and hissing sound. A large earthquake on Unimak, an island in the Aleutian chain, shakes the remote, steel-reinforced concrete Scotch Cap lighthouse, which stands about 100 feet above the North Pacific. Following a 9.0 quake off the west coast of Northern Sumatra, over 230,000 people perished in the Indian Ocean tsunami, which struck 15 countries.


The Pacific Tsunami Warning Center, established in Hawaii in the wake of the deadly 1946 tsunami, is a nexus in the global warning network. Tsunami warnings are now triggered automatically, says Masterlark, based on measurements of earth movement. Further confirmation of the size of the wave may come from special purpose ocean buoys, if they are in the right place, Masterlark says. In terms of generating tsunamis, not all underwater earthquakes are created equal, says Andrew Newman, assistant professor of earth and atmospheric sciences at Georgia Tech.
These large tsunamis come from a smaller break in the ocean floor, and so contain relatively little energy and do not travel well across the ocean, Newman says. Newman and colleagues have developed software to detect the peculiar signature of the tsunami earthquake, and are now running it on a research basis. Although the Japanese had little time between the earthquake and the tsunami, Newman says the national warning system did work. But the rising casualty counts highlights the deadly role of proximity to the quake, says Masterlark. Seismologists are loathe to predict earthquakes, but in the past decade or two, they have recognized that earthquakes occur in series along major faults in Turkey and Sumatra, as big quakes place extra stress on the adjacent fault. The large quake in 2005 did not cause a major tsunami, but its timing, just three months after the Dec.
Naar aanleiding van de aardbeving en tsunami in Japan zet Zynga een actie op getouw in FarmVille. Wanneer je Farm Cash doneert 25, 55 of 240 zal je in staat zijn om Daikons te zaaien en te oogsten op je boerderij.
Dan zou niemand farmcash hoeven te kopen, en dan kan er ook geen geld naar japan gaan natuurlijk. En aangezien ik het eerste niet niet heb, en met zo’n systemen niet wil werken( wat is er mis met de gewone bankoverschrijving?) zal ik een andere manier moeten zoeken om de mensen in Japan te steunen. The day after Japan's biggest earthquake, cities smoldered, soldiers lent helping hands, and a nuclear reactor exploded. Smoke billows from Japan's Fukushima I nuclear reactor as a man watches the scene unfold on TV Saturdaya€”the result of damage to the reactor's cooling system during yesterday's earthquake and tsunami. Flattened buildings smolder in an aerial picture of the Japanese town of Yamada on Saturday, the day after a magnitude 8.9 earthquake and tsunami hit the region.
A plea for help fills a school playing field in the port town of Minamisanriku in Japan's Miyagi Prefecture on Saturday. A fire truck attends to burned-out cars at the Hitachi Harbor port northeastern Japan on Saturday.Japan's three largest automobile manufactures a€“ Toyota, Honda, and Nissan a€“ have announced they will temporarily halt production at all domestic assembly plants following the earthquake and tsunami. Tsunami-tossed cargo containers litter the ground Saturday in Sendai, Japan, where the local airport was nearly completely flooded by Friday's three-story-tall wave.Limited air traffic resumed at major Japanese airports on Saturday, but most were packed with stranded passengers, the Los Angeles Timesearthquake is, but I've never seen anything like this," Seven Nia, a Los Angeles businessperson, told the paper. The moon jellyfish can age backward, form hordes of clones, and regenerate lost body parts, a new study says. An Iraqi dam break would not only kill hundreds of thousands, but also wipe out millennia of history. As a natural disaster there are so many other factors to consider when responding to the incident. 11, 2011, apparently did not collapse high-rise buildings, the ensuing tsunamis flattened vast areas along the northeast coast.
After the reactors automatically shut down during the quake, emergency systems for removing heat still being generated in the reactors were routinely switched on.


Such quakes often occur where one of Earth’s tectonic plates dives, or “subducts,” beneath another. Even though earthquakes disturb the bottom of the water, the analogy works: just as a larger stone, thrown faster, makes a larger wave, the size of the tsunami depends on extent and speed of the ocean-floor movement. They can be spaced as much as one hour apart, so subsequent waves can kill those who return to help victims of earlier waves.
Striking a totally unprepared town during a festival, the wave kills 27,000 and destroys more than 10,000 houses.
Minutes later, a huge wave obliterates the lighthouse, leaving practically no trace of the five Coast Guardsmen inside. At the time, Indian Ocean nations lacked an ocean-wide warning system, causing the tragedy to strike without warning. Since almost all tsunamis originate in earthquakes, the warning centers rely on data from seismographs, many of them located on the unstable ring of fire. But they also offer less warning because local people do not feel the massive shaking associated with a major tsunami. However, the upper stories of tall, reinforced concrete hotels can provide refuge if you have no time to move inland or to higher ground.
26 monster, suggests a compelling reason to focus intensively on the earthquake zone in the Japan trench, says Masterlark. 24 uurin farmville is 23 uur ze krijgen de klok niet goed DUs 6 uur is ongeveer 5 uur en 45 minuten.
About 7,500 people have been evacuated to shelters since the earthquake and tsunami, the BBC reported. Tom Phelan share their insight into the emergency response side of the after effects of these events. The death toll is swelling steadily as bodies wash in on the surf, and citizens and Japan’s Self Defense Forces scour a landscape turned upside down by inconceivably powerful waves.
As fires ignited by overturned candles ravage the city, residents seek relief from the heat near the waterfront. Fishermen at sea don’t notice the deadly wave and return to an ocean strewn with the corpses of loved ones and the wreckage of their homes.
Five hours later, the tsunami slams into Hilo, Hawaii, obliterating the waterfront and killing 159. Ignoring warnings, many residents stay in homes near the bay, increasing the death toll by 61. Even a warning system would have had limited utility to close-in coastal communities, given the jet-like speed of the waves. When the water turns to steam, the explosion causes tsunamis that cause most of the 37,000 deaths on nearby Sumatra and Java.
Much of the video you see is from helicopters, or people watching from two or three stories up in buildings.
