A second earthquake with a preliminary magnitude of 3.5 strikes the Los Angeles region, just hours after a 3.8-magnitude quake shook the Malibu area.
An earthquake with a preliminary magnitude of 3.5 rattled the L.A. metropolitan area early Saturday.
According to the U.S. Geological Survey, the quake struck at 6:30 a.m. The epicenter was said to be approximately 11 kilometers (about 6.8 miles) away, at a depth of 14.4 kilometers (about 8.7 miles).
Los Angeles is located in a seismically active region, making it prone to earthquakes.
According to the United States Geological Survey (USGS), LA experiences over 10,000 earthquakes annually, but most are minor and not felt by residents.
The city's most destructive earthquake was the '1994 Northridge quake' , which caused 57 deaths and $20 billion in damages.
Earthquake-resistant construction is mandatory for new buildings in LA, but retrofitting existing structures remains a challenge.

No Immediate Reports of Damage or Injuries
There were no immediate reports of damage or injuries following the earthquake. This quake came just hours after a 3.8-magnitude quake shook the Malibu area shortly before midnight Friday.
