A suspected sewer gas explosion in Wuhan, China caused a road to erupt underneath workers and passers-by, injuring at least 4 people.
Traffic cameras captured the terrifying moment in full just after 9 a.m. local time Thursday.
As a man on an electric bike rides past the pair, a column of fire suddenly shoots out of the manhole and reaches several feet above the road surface. The momentary blast sends both workers’ hard hats flying off their heads as they each turn to avoid the flames.
Just as they turn around, the asphalt beneath their feet begins to bulge and bursts open, leaving large cracks in the ground from which gas appears to escape. Witnesses who hear the eruption turn and run the other way.
In the footage, the nearby e-bike rider has his back turned to the explosion and is unable to respond in time as the road beneath his feet violently erupts and throws him clean off his vehicle. The rider flies headlong toward the ground as the road settles once more and blast debris falls from the sky.
Wuhan news portal Jimu quoted local residents who said they heard a “loud explosion” at the time of the incident. One store owner said she tended to the male victim who flew off his e-bike, and who was “conscious but howling in pain.”
The Hongshan District Emergency Management Bureau said first responders reported four victims from the blast. According to an online statement put out on Weibo, they were taken to a local hospital for treatment but were not in life-threatening condition.
It was unclear whether there were any people in the sewer at the time.
The district office’s statement said the blast was not caused by a natural gas leak. The probability was ruled out by city inspectors sent by the local utility company.
The authorities are reporting the incident as being linked to a suspected build-up of methane gas in the sewers. The two workers caught at the front of the explosion were conducting maintenance work of the underground water mains. An investigation is ongoing into the precise cause of the ignition. [newsweek]
