The governor of California has declared a state of emergency in a suburb of Los Angeles over the leaking of methane gas from an underground storage field, according to BBC.
Jerry Brown ordered "all necessary and viable actions" be taken to stop it.
More than 2,000 families have been moved from their homes and many people have reported feeling ill because of the leakage, which began in October.
It stems from a vast underground storage field in Porter Ranch, on the outskirts of Los Angeles.
Residents have been complaining of nausea, headaches and other symptoms, but the utility company says that "scientists agree natural gas is not toxic and that its odorant is harmless at the minute levels at which it is added to natural gas".
