What magnitude was Tohoku earthquake?
9.0 magnitude
The 9.0 magnitude earthquake and the arising tsunami that destroyed Tohoku, Japan on March 11, 2011.
How did the tsunami affect Japan?
A tsunami can cause radiation resulting from the destruction of nuclear plants. In March 2011, in Japan, this disaster produced a great environmental hazard by washing away the four reactors in the Fukushima nuclear facility. The event contaminated a very large state with radiation, forcing mass long-term evacuations.
What caused the Tohoku earthquake?
The 2011 Tohoku earthquake occurred in a subduction zone known as the Japan Trench. 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 two plates were rough and bonded together, building up large quantities of energy.
What is it about an earthquake that causes a tsunami?
Most tsunamis are caused by earthquakes generated in a subduction zone, an area where an oceanic plate is being forced down into the mantle by plate tectonic forces. The friction between the subducting plate and the overriding plate is enormous.
What is a tsunami in Japan?
A tsunami (from Japanese: 津波, “harbour wave”; English pronunciation: /suːˈnɑːmi/ soo-NAH-mee) or tidal wave, also known as a seismic sea wave, is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.
