to hydrogen gas that built up within their outer containment buildings after cooling system failure resulting from the loss of electrical power.

ConclusionAs scientists have recorded, this

tsunami/underwater earthquake was the most vast to ever have struck japan in history, and probably years to come.

I see why the scientists would think that, as this event was a HUGE eye-opener for Japanese civilians in the area, because this tsunami caused a crazy amount of destruction.
