It felt big in Irvine, lasted a few seconds, maybe 10

That was nasty! Shook the ***** out of us in Burbank. Called people on the Westside. Shook there too.

Started out small and then got bigger. Really rolling out here in thousand Oaks. There was a 3.1 in San Bernardino this morning...I wonder if it was related.

Major rolling near the long beach area, lasted a long time with large swells but fairly gentle.

5.8

Yep....revised.

That was weird. First time I experienced a quake sitting at a stop light in my truck. Felt like the back end was being lifted. Seemed like forever because you never know when the big one is coming. Could be a precursor for the biggy.... hang on.

Glad to see my cracked chimney is still only cracked. :D Wow.. another aftershock as I type this. STOP ALREADY!!

Got a good shake here on the third floor in UTC. Called home (North = closer to Chino) and the family didn't feel a thing...

all those cows in Chino are giving milk shakes.

Hard to tell on the USGS site, but it looks like they've had about 5-6 aftershocks already.

It's raining here today.:D

Are those the "happy cows" that you Cali folks are so proud of? :p

I am on the 7th floor of a 12 story building and it took a couple of minutes for the building to stop shaking near LAX...

Thats a good thing. I'd rather take a whole bunch of small ones then a big one. Aftershocks is just the ground settling, right mike?

We can blame cgarr for this one! He wanted his son to experience all of socal. ;)

Moderate. Kinda' interesting.

I thought the Hector Mine quake felt a lot stronger even though it was further away - just something about it made me think right away "that's a nasty one somewhere" and sure enough, it ended up being a 7.something. I figured this one was about a 6 within 50 miles, so that's about right.

Can't wait for the sensationalist media to start going "are you prepared for the big one?" and crap like that for the next two months...

Basically....

Decent shaking for several seconds here in North County, San Diego.

Two story wood framed house moved pretty good and pictures on the wall rocked too.

It was the same magnitude as the Whittier Narrows quake in 1987 and I think there was more damage then. We'll see.....

Raining here too.

Not much built off the ground in the Chino Area, the freeways are on the ground and not so many old buildings like in Whittier. Chino is mostly new construction.

Whats with all the rain lately. Kinda spooky if you ask me.

My kid just called me from Newport Beach, out there for Water Polo Junior Olympics this week, Said "Dad, this was so cool, the highlight of our trip, the whole building was shaking" Yea, he is lucky. He cant wait to get home now!

I told him when he left, you might get to feel an earth quake, well I guess he did!

I Thought this one might be blamed one me!!:eek:

I was working in an oil refinery in santa fe springs when that one hit, almost on top of the epicenter. Scared the poop out of me. For some reason I remembered it being bigger than a 5.8 but that was a long time ago.

Nope, the whittier quake wasn't as big as i thought. it just felt like it:

The Whittier Narrows earthquake struck the southern San Gabriel Valley and surrounding communities of southern California at 7:42 a.m. (Pacific Daylight Time) on October 1, 1987. The magnitude 5.9 earthquake was originally assigned a magnitude of 6.0 but was revised a few days later when additional data became available. Its epicenter was actually in the town of Rosemead, California, at a depth of 11 km.

The earthquake was caused by slip on a blind thrust fault near the northern end of the Whittier Fault, part of the Elsinore Fault Zone, on a previously unknown fault structure. There was no surface rupture. It has been proposed that the event occurred on an extension of the recently recognized Puente Hills thrust system.[1]

A magnitude 5.3 strike-slip aftershock occurred three days later, on October 4, causing additional damage.

Three people died as a direct result of the earthquake. One death was of a Southern California Edison worker buried by a landslide in the Muir Peak area of the San Gabriel Mountains while working with a crew installing the footings for a high tension power tower north of Pasadena, California. Five other deaths are attributed indirectly to the event. About $358 million USD in damage resulted.[2]

I didn't feel a thing.

It totally depends on where you are, and distance isn't necessarily the biggest factor - depends on the geology.

I was in marina del rey - 4th floor doctor's office and my ortho was filling a syringe to give me a shot when it happened. I'm amazed it was only 5.8 as it was a *long* roller - easily 30-45 seconds.

I've been through a bunch of quakes here. The scariest being an aftershock of the Whittier Narrows quake in '89 that hit at about 3am (I was living in Pasadena), and then the '94. That one felt like it picked up the house and dropped it back down (again, in Pasadena).

Good one here in Burbank.

sister felt it in burbank, she was perrrty scared

I was in the air and space gallery... imagine having an F-20 and a T-38 hanging on cables over your head. :eek:

I saw the news on CNN at lunch just now. My first thought: "I wonder how quickly this will make it onto PPOT?"

The wife was sitting at a signal and thought she was rear ended. She says car was rolling back and forth and side to side.. Our quakes are usually early morning I think

Any of you guys remember Northridge, or even farther back Whittier-Narrows or Sylmar? Those were some shake and bakes. :eek:

I think the sylmar quake was in 1972? I was 12 and I remember the bed moving all over the room. Pool had some pretty big waves too!

I was 15 and slept throught the sylmar quake. Now if the dog farts, I'm up.

Whittier narrows quake I was up a fixed ladder 30 ft off the floor inside a plastics plant working on a conveyor system. I about broke my thumb flying down that ladder.

Not a single house in my neighborhood had a chimney after Northridge. And we weren't even in The Valley.

Northridge was crazy! I was living in Burbank on the 3rd floor of an apartment building.

I just called a neighbor who's in Florida right now. He thinks he likes earthquakes because the highest one he's been through is a 4.8. I told him when they get close to a 6 and it's nearby, he'll change his mind.
