Japan sits at the junction four major tectonic plates, it is why the area so geologically but I will. And why the japanese are so well prepared to deal with the threat. So, what went wrong in 2011. The problems begin on March the 11th. Earthquake detection systems predict a huge tremor with the magnitude of 7.2 warnings are sent out. Chris Alderson has lived in Japan for thirteen years, He is come to expect such tremors is an everyday part of life.
Earthquake, is officialy common that people do not usually concern themselves with mobily. Some minor, they believe as their comment, others people back up there is little bit point out the earthquake to their coworkers and get back to their work, said Alderson.
At 2:46 p.m. local time. The earthquake hits, with the magnitude-9, it is a hundred times more powerful than predicted.
You tend to expand to fade away as usual instead they serve grew in strength intensity to extend the numbers that experience before, said Alderson.
It is the largest known quake in Japanese history, one of the five most powerful ever recorded. The quake’s epicenter 65 kilometers of Japan’s east coast, where 300 kilometers section of the earth’s crust has pushed upwards by about 5 meters. It is a seismic event known as an undersea megathrust earthquake. The forcible shockwaves is so enormous japan moves two and a half meters, and the axis of the entire plane shifts about 18 centimeters. Despite the magnitude of the quake precautionary measures limit the damage.
There is a great deal of education among Japanese population, but how to behave during such disasters. So, lost his concern they was in the so terrified panic which one might suspect, said Alderson.
It appears technology is protected the Japanese, but the earthquake is just the first phase of a double disaster to face that day. Because the tremor has given birth to a tsunami, and it is heading towards Japan’s northern coastline. Coastal engineer Allison Raby has been studying why the offensive 2011. Escalated into one of the worst disasters of its kind placing it in the top 10.
We going to stimulate that make a thrust type events. Using this hinged cool time here that is going to represents the edge of the crust comes up, not type rupture and we can just bring that plate up class going to raise a huge body of water, said Allison.
In open water the initial wave is relatively small just a meter high, but as it approaches the shoreline and enters the shallows it begins to slow, and growing high. All too aware earthquakes can cause huge waves. Japan has a sophisticated tsunami warning system.
In Japan when there is and tsunami warnings automatically generated which a heard on cell phones, brought on television stations. Immediately people were aware that something was going on, added Alderson.
Along Japan’s northeast coast line, people begin to evacuate or take refuge in designated shelters.
Japan had wanna be best defended coastlines in the whole world, and we created certain parts of the Japanese case line. We start here in the city of Kamaishi. Kamaishi was a deep-water ports and I had to the world’s deepest breakwater. This was protecting the very large steel factory and a large population. For the safe we had the settlements have Minami Sanriku and we recreated one of the vertical evacuation stretches. This was clearly signed to say that people who are on their grounds could escaped from the incoming wave, and then we move into the coastal plains. Now these were protected by concrete developments and behind that is a pine forest and those were all designed to protect the settlements behind, said Allison.
The Japanese had taken a calculated risk, the fortifications are only designed to cope with waves up to 12 meters high. But the tsunami surging to watch them as a monster peaking at forty meters. In Tokyo Chris Alderson is stunned by what he sees.
Allison Raby recreates the tsunami in miniature. By comparing footage from each the town’s hit by the tsunami, to the model Recreation’s a demo can help understand why the best defenses on the planet failed so catastrophically. Not only did the trees do little to stop the wave, the shattered stumps added to the deadly flow. Making the tsunami even more leaks. The shelter in Minamisanriku remained intact, but many similar shelters were too close to the shore. With over a hundred ending up on the water the man and after the tsunami first. The state-of-the-art come I she break waterworld lame pieces. To help the victims Chris Alderson heads north to the flood zone.
We went from the hundred and day-to-day life in the big city to suddenly traveling through what appeared like the set from a science fiction post holocaust movie. To suddenly see these people tone from their homes, to see the scale this destruction and death were boaters dropped in the Middle Village or large articulated truck is stranded on the roofer factory it was unworldly it was very difficult to believe that this was a new reality, said Chris.
The disaster gets even worse when a flooded reactor at the Fukushima dai-ichi plant meltdown. Thanks to the courage to the reactor workers the situation is brought under control. The tsunami leaves over two hundred billion dollars worth of damage in its wake. Making it the costliest natural disaster ever.
