Fukushima:

- hit by earthquake at or above upper structural limit. The most powerful earthquake ever recorded in Japan

"maximum ground g-forces of 0.56, 0.52, 0.56 at units 2, 3, and 5 respectively. This exceeded the seismic reactor design tolerances of 0.45, 0.45, and 0.46 g for continued operation, but the seismic values were within the design tolerances at units 1, 4, and 6"

- hit by tsunami exceeding that limit

The largest tsunami wave was 13–14 m (43–46 feet) high and hit approximately 50 minutes after the initial earthquake, overwhelming the plant's ground level, which was 10 m (33 ft) above the sea level
