Tokyo Electric Power Company ( TEPCO ) submits a report to Japan 's nuclear safety agency which predicts the possibility of a tsunami up to 10.2 metres high at the Fukushima Daiichi nuclear plant in the event of an earthquake similar to the magnitude 7.2 earthquake with accompanying tsunami that devastated the area in 1896 . TEPCO actually made this prediction in 2008 but delayed in submitting the report because they '' " did not feel the need to take prompt action on the estimates " ''
