Approximately 10,000 gallons of crude oil has leaked onto the streets of Los Angeles after a high-pressure pipe burst.
It is believed to have covered a half-mile area and is knee deep in some areas.
Locals have tweeted pictures of the flowing oil on the streets:
Approximately 10,000 gallons of crude oil sprayed on to the streets of Los Angeles after a high-pressure pipe burst. The oil was seen shooting up into the sky and onto streets and nearby businesses.

Oil prices fell sharply today after world powers struck a landmark deal with Iran to curb its nuclear programme in exchange for an easing of international sanctions.
While Iran will not be allowed to increase its oil sales for six months, any easing of Middle East tensions tends to lead to lower crude prices.
A British oil worker kidnapped in Indonesia has been released, the Foreign Office has said.
Engineer Malcolm Primrose, 61, was ambushed by an armed gang as he travelled home from a drilling site in the Aceh region on Tuesday, local reports said.
The Foreign Office said that the 61-year-old is "safe but tired" after his release, which followed a police search of the local area with the assistance of soldiers.
No arrests are known to have been made at this stage.
Downing Street said that Mr Cameron has not spoken with BP about their concern about the rising compensation costs from the 2010 Gulf of Mexico oil spill, nor did he raise the issue with president Obama or other US authorities during his visit last week. A Number 10 spokesperson said:
British Petroleum has warned that millions of dollars of "fictitious" compensation claims for the 2010 Gulf of Mexico oil spill are putting the company at risk.
BP has sought an injunction to stop payouts to US companies it argues are claiming fraudulent or inflated losses from its £5.4 billion compensation pot.
An appeal document by the group argues that businesses in the US have been handed millions of dollars for "non-existent, artificially calculated losses", according to reports.
BP warned in the court filing that it will be "irreparably harmed" unless the compensation system is reformed.
British Petroleum has urged David Cameron to step in over the company's rising compensation costs for the 2010 Gulf of Mexico oil disaster, according to the BBC.
The company feels its financial recovery is at risk due to these costs and BP also worry that they could become a takeover target, the report says.
BP, who reportedly feel the compensation system is being abused, has urged the Prime Minister to bring up this issue with the US government, the BBC suggests.
The 2010 disaster killed 11 oil rig workers and around four million barrels of oil poured into the Gulf of Mexico.
In 2012, BP agreed to pay £5.4 billion in compensation but the company now expects that cost to be higher.
The price of petrol at UK pumps has increased significantly since 2004, but the majority of that is down to tax.
In 2004 a litre of petrol cost, on average, 80p - 59p of which was tax. In 2012 the average price jumped to £1.36 as tax rose to 81p:
But despite the price of petrol increasing in the UK, the Office of Fair Trading found that - pre-tax - the country has some of the cheapest road fuel prices in Europe:
The Office of Fair Trading (OFT) has defended its investigation in to petrol pricing saying that it lacked information:
In January the OFT found that price rises were driven by tax rises and the hike in the oil price, and said it found "very limited evidence" that retailers were not passing on drops in the wholesale price to drivers quickly enough.
A Conservative MP blasted an Office of Fair Trading (OFT) inquiry into petrol prices as "limp-wristed and lettuce-like" in the wake of price-fixing allegations.
Harlow MP Robert Halfon, who has campaigned for cuts to duty and greater transparency in the market, said despite the Commons unanimously calling for a thorough probe into petrol pricing, the regulator failed to spot any of the allegations currently under review.
Mr Halfon said: "Do you not agree that what happened was the OFT carried out a limp-wristed, lettuce-like inquiry when they should have done a full 18-month inquiry into what has been going on?"
Energy Secretary Ed Davey defended the OFT as an "independent body, a strong body", which has powers to determine its own investigations.
Mr Davey made a statement updating MPs on the launch of a European Commission investigation into oil companies BP, Royal Dutch Shell and Norwegian company Statoil.
