The Fukushima Daiichi nuclear power plant had a seawall designed with withstand a tsunami with waves 5.7 meters (19 feet) high. It was hit by a tsunami with waves of 14 meters (46 feet). For a wave of this height, the seawall that was in place was hardly better than nothing at all. The plant also lacked the water proofing that saved the Fukushima Daini plant from a similar fate.
A review of historic tsunamis produces the rather disturbing revelation that ten tsunamis with waves of over 10 meters in height have hit Japan since 1707, or one about every 30 years. Three of these have hit the Sanriku Coast, where the Fukushima Daiichi plant is located, since 1896. The 1986 tsunami had a maximum wave height measured at 38.2 meters, the one in 1933 had a wave maximum of 28.7 meters, and the one in 2011 had maximum waves of 33 meters. Clearly, the 14 meter waves that hit Fukushima Daiichi were neither the worst case, nor even unprecedented.

What is Fukushima?
Fukushima is a town in Japan that suffered from a strong earthquake and high tsunamis that broke down the electric grid forced the nuclear power units shut down.
What was the epicentre of the recent big tsunami in Japan?
Tsunamis do not have epicentres. Earthquakes do. Sometimes, as in the case of Japan, earthquakes cause tsunamis.
How high were the waves in the Fukushima Tsunami?
The wave that went over the seawall at Fukushima Daiichi was 14 meters, or about 47 feet, tall. The seawall was 5.7 meters, or about 19 feet. At other places along the coast where the Fukushima plants are located, the waves were as high as 33 meters, about as tall as a 10 story building. Historic tsunamis in the same area had similar size in 1896 (38.2 meters) and 1933 (28.7 meters). There is a source link to an article on historic tsunamis below.

When did the Fukushima accident take place?
The earthquake that caused the accidents was on Friday, March 11, 2011, at 14:46 JST. The first tsunamis from the earthquake hit the Fukushima Daiichi plant about 40 minutes later, and were followed by the tsunami that overwhelmed the plant about 20 minutes after that. The earthquake and tsunamis were just the start of a series of accidents that unfolded in time. There is a link below to a timeline for these events.
