He is now a professor at Tohoku University in Sendai, Japan.

It has been used as a shelter for survivors of the 2011 Tōhoku earthquake and tsunami.

Social media helped me in a couple of ways during the Great Tohoku Kanto Earthquake.

Events President Barack Obama visited the embassy to express condolences over the 2011 Tōhoku earthquake and tsunami.

PASADENA In 2011, the Tohoku earthquake and tsunami devastated Japan s coastal region.

Back in March 11, 2011, a 9.0 earthquake off the Pacific Coast off Tohoku struck Japan. This, the strongest ever earthquake recorded to hit Japan, and the subsequent tsunami waves of up to 40.5 meters devastated great parts of the coastal regions of the country and caused the meltdown of nuclear reactors at the Fukushima Daiichi Power Plant, irradiating the neighboring areas including the ocean waters.

The Yamaguchi gumi also provided relief in the wake of the 2011 Tōhoku earthquake and tsunami by opening its offices to the public and by sending supplies to affected areas.

Radiation remains a serious problem for residents in the area surrounding the Fukushima Daiichi Nuclear Power Plant since the plant suffered a meltdown following the 2011 Tohoku earthquake and tsunami.

More recent major quakes are the 1995 Great Hanshin earthquake and the 2011 Tōhoku earthquake, a 9.0 magnitude quake which hit Japan on March 11, 2011, and triggered a large tsunami.

But, in many areas, the Tohoku tsunami overflowed and even destroyed these protective structures including the seawall at the Fukushima Daiichi nuclear power plant in northern Honshu.

And, as Japan s recent experience demonstrated, protecting against the most powerful threats such as the 9.0 magnitude Tohoku earthquake and the subsequent three meter tsunami would require massive, costly construction projects.
