auxiliary information: The 2011 earthquake off the Pacific coast of T≈çhoku was a magnitude 9.0 undersea megathrust earthquake off the coast of Japan that occurred at 14:46 JST on Friday 11 March 2011, with the epicentre approximately 70 kilometres east of the Oshika Peninsula of T≈çhoku and the hypocenter at an underwater depth of approximately 30 km. The earthquake is also often referred to in Japan as the Great East Japan earthquake and also known as the 2011 Tohoku earthquake, and the 3.11 earthquake. It was the most powerful earthquake ever recorded to have hit Japan, and the fourth most powerful earthquake in the world since modern record-keeping began in 1900. The earthquake triggered powerful tsunami waves that reached heights of up to 40.5 metres in Miyako in T≈çhoku's Iwate Prefecture, and which, in the Sendai area, travelled up to 10 km inland. The earthquake moved Honshu 2.4 m east and shifted the Earth on its axis by estimates of between 10 cm and 25 cm, and generated sound waves detected by the low-orbiting GOCE satellite.
