Japanese tsunami

•What happened during the disaster? One of the most powerful earthquake, in record books, shook before the tsunami at a rating of 8.9 on the ritcher scale. The power caused a violent uplift on the sea floor 96km off the cost of Sendai, where the tectonic plates in the Pacific Ocean, slid beneath the plate japan sits on. This caused the tsunami that raced through hundreds of towns and killed thousands of people in 2011. On the boarder of the tectonic plates around 12 km of crust ruptured along the trench. The earthquake occurred at a relatively shallow depth of the ocean at just 17 km, because of this most of the power was released at the seafloor. •How many people were affected? In the earthquake and tsunami altogether killed 15,891 people. Pretty much all the rest of the people lost their property or houses. Death from fire in the water is 165 people. The confirmed drownings were 14,308. There was also some people that picked up radiation from the nuclear plant there. These devastating numbers still ring in our ears as one of the most tragic disasters in a long time.

•How was property affected? On the 30th of September 2011 over 1 million buildings were damaged. The amount of buildings that were totally destroyed was 117,780, and the amount of partially damaged buildings was 178,239. However there were over 700,000 buildings with minor damage, caused by; earthquakes, tsunamis and the shocks afterward. Almost all of these buildings were based on the coasts of Japan.•How was the environment affected? The environment was affected dramatically with surface ruptures, mass movements like rock falls and landslides, cracks in the ground, hydrogeological anomalies, trees’ shaking and snapping in half. However the mass destruction came from the tsunami itself, as it came and demolished the surrounding areas on the coast. There is still a vast majority of japan that was left unaffected by the tsunami. The tsunami hit really hard on the northern shores of Honshu (Japan’s largest island) where almost all manmade and natural environments met their demise. This area was also the most damaged from the earthquake and the consequences were paid with the destruction of roads, railways, houses, vehicles and the people.

•Who responded and how? After the tsunami and earthquake ninety-one countries and nine international organizations helped japan. Search parties littered Japanese streets in search of survivors and wounded people who were I need of help and took them in. organizations such as Red Cross or the Salvation Army provided clothes, food, water and shelter to all those who needed it. After everyone was taken care of, groups of policemen, firefighters and any other volunteers, helped clear out the rubble and fix anything that needed to be fixed. Then the rebuild started to shape japan back to what it is today.

• what obstacles to theresponse might have been encountered?There were a few major obstacles that responders had to face. One of the obstacles they faced was transport. How are they going to get to japan when they can’t land a plane there and can’t drive there? There are reasons that they can’t fly there such as; there’s too much rubble or there’s massive bodies of water blocking their way. Another obstacle was accommodation in japan. Where were they going to stay when everything was destroyed? There are reasons they can’t stay in any building that’s standing such as; there was no electricity and there was no water supply. But one of the most major ones was that there was radiation that had leaked from the nuclear plant, which meant that a lot of people were in danger. The responders must have gotten through it all though, because they saved hundreds of lives.
