The 2011 earthquake off the Pacific coast of Tōhoku was a magnitude 9.0–9.1 (M w ) undersea megathrust earthquake off the coast of Japan that occurred at 14:46 JST (05:46 UTC) on Friday 11 March 2011, with the epicentre approximately 70 km east of the Oshika Peninsula of Tōhoku and the hypocenter at an underwater depth of approximately 29 km.wikipedia Earthquake and Tsunami near Sendai, Japan. The epicenter was detected 64 miles off of the Sendai coast and was estimated to be only 18.6 miles below the surface. A part of the subduction zone measuring approximately 190 miles (300 km) long by 95 miles (150 km) wide lurched as much as 164 feet (50 metres) to the east-southeast and thrust upward about 33 feet (10 metres). More than 127,000 buildings collapsed and almost 16,000 people died. The tsunami raced outward from the epicentre at speeds that approached about 500 miles (800 km) per hour. The 9.1 magnitude (Mw) undersea megathrust earthquake occurred on 11 March 2011 at 14:46 JST (05:46 UTC) in the north-western Pacific Ocean at a relatively shallow depth of 32 km (20 mi), with its epicenter approximately 72 km (45 mi) east of the Oshika Peninsula of Tōhoku, Japan, lasting approximately six minutes.
