The Mw 9.0 destructive earthquake that occurred March 11, 2011, in Japan was associated with widespread liquefaction within a 650-km long zone that extended in the eastern part of Japan. Based on reconnaissance surveys of the earthquake, recurrence of liquefaction at the same sites was identified at ninety sites where liquefaction had occurred during the previous earthquakes such as the 1987 Chibaken toho-oki and the 1978 Miyagiken-oki earthquakes.
