yikes!!

It just broke news on ABC. They say it lasted 20-30 seconds as far away as Las Vegas. The largest in LA since 1994 (North Ridge).

It's been downgraded to a 5.4. I don't know if that makes much of a difference in anything.

I ran errands this afternoon stopping a local market with homegrown produce (corn, tomatoes, etc.). Didn't expect to see a TV in the store but they had Fox News tuned in. First I had heard of a 5.4 earthquake. You kind of go into a breaking news mode, it was all I could think until I got home to watch CNN, MSNCB and Fox.

I hope we don't hear of injuries.

[JessRomero]

My friend that lives in San Diego called me and told me that it shook pretty good but nothing bad. But her dog started acting really weird a few minutes before so she knew something was going on because of how he was acting he usually knows before they do and it gives her a few minutes to get her kids together! Thank god for dogs! I would take a storm over a earth quake anyday!

[JonathanBelles]

The earthquake seems to have shook up the Big Brother House!

[Stephanie]

After the fires, this is the last thing that they need. I hope it's not a precursor to something larger. Hopefully this one relieved enough pressure in the plates so that another one doesn't come about.

[CajunMama]

You're so right stephanie. The fires were bad enough. They don't need earthquakes now.

[RL3AO]

Just hope this isn't the 1 in 100 times that its a foreshock.

[masaji79]

Let's hope not!

Looks like a Swarm Progression to me.

Last month Mexicali quakes up 600 %
This month L.A. 138 quakes that seems like a lot.
Next month ?

Another aftershock rumbling through.
