A roaring inferno has engulfed 45m of wharf at the Port of Los Angeles, the port’s warehouse in Wilmington was also affected.
More than 100 fire-fighters fought the blaze from land, air and via several sea-bound vessels.
Divers with hoses were also deployed.
Katherine Main, a spokeswoman with the Los Angeles Fire Department said the fire, which took place under a steel warehouse, had threatened nearby cargo-ships.
The blaze was under control by 20:30, September 23, 2014.
Main went on to say that the warehouse did not appear to catch fire, although the dock beneath it was burned.
Around 850 terminal employees were evacuated as a precaution, and cargo ships were asked to move away from nearby berths.
There were thought to be hazardous materials at the dock, causing fire-fighters at the scene to wear breathing masks.
