Oil slick in California - level 2
An underground pipeline suddenly burst on Tuesday morning, and as much as 397 cubic metres of oil gushed into the sea.
The oil blackened a 4-mile beach in California and left two oil slicks in the water. Clean-up crews worked all day and all night for three days to remove the oil.
The company responsible for the pipeline publicly apologised. People are now investigating the incident.
Difficult words: burst (to break open), gush (to flow in large quantity), oil slick (when oil sits on water).
