A predawn earthquake jolted some Angelenos awake just before 4:45 this morning.

The quake, with a preliminary magnitude of 4.0, has an epicenter at Hollywood Park, a few blocks from the intersection of W. Century and Crenshaw boulevards. There were no immediate reports of damage.

According to the United States Geological Survey, about half an hour prior to the 4.0 temblor, two smaller quakes struck in the same area — a 3.3 and a 2.5.

In addition, there have been a number of smaller aftershocks.

Don Blakeman, a geophysicist at the National Earthquake Information Center, says aftershocks are common with a 4.0 quake.

"Or it could just be what we call a swarm — just a number of small quakes — not exactly a main shock aftershock situation," Blakeman told us. "There's also a very, very, very tiny possibility there could be a much larger quake. And that's just in general, anytime we have quakes somewhere in a seismically active area, there's always the possibility of a much larger quake."

The Southern California Seismic Network at Caltech puts the chance of a larger quake happening — larger than a magnitude 4.0 — at 5%.

If you felt the quake, you can let the USGS know about what you experienced at: Did you feel it?

USGS officials said that they did issue an alert, but because the quake was under 4.5 magnitude it was not sent to mobile phones.
