Explosion at Hoover Dam as transformer catches fire
There’s been an explosion of a power transformer at the Hoover Dam in the United States.
Authorities say no one was injured when a transformer at Hoover Dam caught fire.
Videos posted on social media showed what appeared to be a fire or explosion in a building near the base of the dam.
A huge plume of black smoke swirled above the building.
The fire broke out around 10am and took half an hour to extinguish.
Authorities say there’s no threat to power supplies generated at the dam.
The cause of the explosion is now under investigation.
According to the federal Bureau of Reclamation, the dam is 726 feet (221 meters) tall and 660 feet (201 meters) at its base, as long as two footballs fields measured end-to-end.
As many as 20,000 vehicles a day drive across the 45-foot (14-meter) wide top of the dam, which is a National Historic Landmark.
