Methane gas from the sea floor caused a foul odor on Sunday that prompted nearly 100 emergency calls from residents reporting the stench from Santa Monica to West Los Angeles, officials said.
The odor, which smelled like sulfur, was first reported late Saturday, air quality officials said. The smell wafted in from the Santa Monica Bay.
Justin Walker, a Santa Monica Fire Department spokesman, said hazardous-materials crews found small increments of methane gas in the air at 8:30 a.m.
The amount of methane in the air was not considered dangerous, Walker said, adding he's heard of this type of incident happening up to six times in the last four years.
Hazardous-materials crews were called out after dispatchers reported some 80 calls to 9-1-1 of residents reporting the stench.
