The hypocenter of the quake lay in the Pacific Ocean off the Sanriku coastline. The quake, also called the 2011 Earthquake off the Pacific Coast of Tohoku, occurred at the boundary between the North American Plate on which the Tohoku area of Japan lies and the Pacific Plate that subducts the NorthAmerican Plate.
