The 2011 Tohoku earthquake occurred in a subduction zone known as the Japan Trench. 13 September 2017. Here are some of the amazing facts about the Japan earthquake and tsunami. The ship started its journey in Hokkaido. 3. Now, a … Trace amounts of cesium-134 and cesium-137 (radioactive isotopes) were found in seawater collected in 2014 and 2015. any area on Earth with one or more common characteristics. large settlement with a high population density. On March 11, 2011, a magnitude-9 earthquake shook northeastern Japan, unleashing a savage tsunami. • The overriding plate above the mainshock was shot out to cause the huge tsunami. The lose of homes, businesses, roads and more would be a tall task to over come but to make it all worse, the tsunami caused a meltdown of three nuclear reactors at the Fukushima Daiichi Nuclear Power Plant. To make matters worse, Japan's nuclear industry was shattered. The temblor also shortened the length of a day by about a microsecond. geographic territory with a distinct name, flag, population, boundaries, and government.

What if you could do something to help people who live in areas that are prone to earthquakes? "For big earthquakes, the tsunami is going to be the big destructive factor," said Vasily Titov, director of the National Oceanic and Atmospheric Administration's Center for Tsunami Research in Seattle, Washington. More than 5,000 aftershocks hit Japan in the year after the earthquake, the largest a magnitude 7.9. The effects of the great earthquake were felt around the world, from Norway's fjords to Antarctica's ice sheet. Residents of Tokyo received a minute of warning before the strong shaking hit the city, thanks to Japan's earthquake early warning system. However, their warnings went unheeded by officials responsible for the country's earthquake hazard assessments. The Chikyu, a Japanese drilling vessel, during a scientific expedition to drill into the fault that caused the magnitude-9.1 Tohoku earthquake. • The mainshock asperity is isolated and so it has large coseismic slip. About 250 miles (400 km) of Japan's northern Honshu coastline dropped by 2 feet (0.6 meters), according to the U.S. Geological Survey. The earthquake was caused by the rupture of a stretch of the subduction zone associated with the Japan Trench, which separates the Eurasian Plate from the subducting Pacific Plate. This was devastating to the area and country. The areas flooded in 2011 closely matched those of a tsunami that hit Sendai in 869. A part of the subduction zone measuring approximately 190 miles (300 km) long …
To make matters worse, Japan's nuclear industry was shattered. These environmental hazards shape human activity regionally. Thank you for signing up to Live Science. The number of confirmed deaths is 15,894 as of June 10, 2016, according to the reconstruction agency. The 2011 Tohoku Earthquake (magnitude 9.0) was of a much higher magnitude than Haiti 2010 which was a magnitude 7.0, as displayed by the relative scales in Figure 9. Follow Live Science @livescience and Facebook. Its full distance was opened 49 days after the quake, on April 29 – a quick recovery for the shinkansen compared to 81 days after the Great Hanshin-Awaji Earthquake in 1995 and 66 days after the Niigata-Chuetsu Earthquake. The total economic cost could reach up to $235 billion, the World Bank estimated, making it the costliest natural disaster in world history. movement of tectonic plates resulting in geologic activity such as volcanic eruptions and earthquakes. When those plates scrape against each other and cause an earthquake, the results can be deadly and devastating. On March 11th 2011, a magnitude 9.0 underwater mega thrust earthquake struck 70 kilometers off the coast of Japan’s main island of Honshu. A magnitude-9.0 earthquake struck off Japan’s northeastern coast. A tsunami—Japanese for “harbor wave”—is a series of powerful waves caused by the displacement of a large body of water.

As of February 2017, there were still about 150,000 evacuees who lost their homes; 50,000 of them were still living in temporary housing, Japan's Reconstruction Agency said. The Pacific Plate slid westward near the epicenter by 79 feet (24 m). When you reach out to him or her, you will need the page title, URL, and the date you accessed the resource. This is an aerial view of damage to Sukuiso, Japan, a week after the earthquake and subsequent tsunami devastated the area in March, 2011. The researchers think that this clay layer allowed the two plates to slide an incredible distance, some 164 feet (50 meters), facilitating the enormous earthquake and tsunami. This earthquake was caused when the thicker North American plate converged with the thinner Pacific plate, forcing the thinner plate down into the Earth’s asthenosphere. The environmental hazards you face depend on where you live. This is just what National Geographic Young Explorer Navakanesh M Batmanathan is trying to do. Join our community of educators and receive the latest information on National Geographic's resources for you and your students. The country's stringent seismic building codes and early warning system prevented many deaths from the earthquake, by stopping high-speed trains and factory assembly lines. The earthquake shifted Earth on its axis of rotation by redistributing mass, like putting a dent in a spinning top. The direct financial damage from the disaster is estimated to be about $199 billion dollars (about 16.9 trillion yen), according to the Japanese government. People in Japan also received texted alerts of the earthquake and tsunami warnings on their cellphones. 1145 17th Street NW the sudden shaking of Earth's crust caused by the release of energy along fault lines or from volcanic activity.
