During the 2011 Fukushima nuclear emergency, four reactor buildings were damaged by hydrogen explosions.

The reactor 3 building is largely uncovered, its roof blown off in a hydrogen explosion over two weeks previously.

Before she left the yard she suffered from a hydrogen explosion.

The hydrogen explosion was like a supernova, turning the sky above into a flaming ball.

Spectrographic and flame temperature records support a hydrogen explosion as the cause of failure.

Thirty miles below, the fusillade of hydrogen explosions continued.

A hydrogen explosion may have occurred as a result of reaction between steam and hot zirconium.

The hydrogen explosion followed when the gas in the bag mixed with the oxygen in the atmosphere.

There were further casualties from the hydrogen explosions, and at least one worker was sent to hospital after an overdose of radiation.

Experts soon agreed that the cause was a hydrogen explosion.
