Tsunami damage at Fukushima Daiichi

Tokyo Electric Power has published some amazing images showing the destruction caused by the tsunami at Fukushima Daiichi nuclear power plant.

An accompanying explainer from TEPCO details the tsunami inundation and indicates where the four pictures were taken. The plant is protected by a seawall, and sits 10 meters above sea level.

Based on high-water marks on the side of buildings, the tsunami waves reached a height of 14- to 15 meters above sea level, thus inundating the area around reactors 1 through 4 with about 4- to 5 meters of water.

Reactors 5 and 6 sit in a different part of the plant and are built 13 meters above sea level. TEPCO estimates the water only reached a maximum of 1 meter around those buildings.

Update: I've added a short video showing one of the tsunami waves hitting Fukushima Daiichi. It's only a few seconds long, but you can clearly see water being smashed upwards several tens of meters as it hits the power station.
