Looks like a 5er: http://www.data.scec.org/recenteqs.html Warning, this site is currently very busy.

Nevermind, SuPu's link is the same image and quickerer.

I felt it at work in the Santa Cruz mountains. No problems here.

Funny, I didn't feel crap...but everyone else in the office did, WTF?

And, I thought you broke another bed.

[CS]

Felt it down here in Thousand Oaks, just west and north of L.A. It was a mere rumble down here. Just enough to make me pause as the blinds rattled a bit.

don't mind us, we're just seceding

Viva Republika de California. Arnold es mi Presidente!!!!

Pfffft...

Don't you remember the last time...

[Greydon Clark]

Earth quakes are a nice way to break-up boring meetings.

Were you TAKING a crap at the time?

I used to live in WAAAAAAAY SoCal in the late 80's and we had a couple above 6. It was pretty wild. (I lived in El Centro....)

Was anyone in a swimming pool at the time?

[CS]

(I lived in El Centro....)

Oh wow. I'm so sorry.

[72Twenty]

Oh wow. I'm so sorry.

Tell me about it. That place sucked - and it was like 27 feet below sea level.

[cololi]

I'm a geology jong, anyone know if there is any relation between the Mt St Helens earthquake activity and this quake? Yeah, I realize they are hundreds of miles apart, just curious.

edit: El Centro is a serious hole.

Agreed, I also lived there at one point, but it was an extremely short stint, thankfully.

It caused some minor damage, too. The city will henceforth be known as Nine Hundred Ninety-Nine Oaks... [cue rim shot]

damn it. I just moved to Ventura, been here almost 3 weeks and still no quakes. totally unfair.

[Arty50]

Only 5.9?

I've created larger tremors after eating a couple of Tommy's double cheeseburgers.

Yeah it is! I played Pop Warner Football there, though. That was my only good memory. That and skateboarding.

My dad got transferred there for his job- he managed the Geothermal plant for Chevron. I remember we'd get little quakes in the middle of the night - just enough to trip the system and he'd have to go out there and reset everything.

Heh heh, I got kicked out of Catholic School there, though!!!

Hope all our Caliwogs are well and fine and watching their mts. grow

On looking at the earthquake map, there appear to have been something like 60 minor to 6.0 earthquakes near Parkfield, California (near Paso Robles). I lived in So Cal for 39 years and experienced a number of over 5.0s, but the one I'll NEVER forget is when I was in Visalia (not too far from this epicenter), my grandma was in the bathroom and the whole floor just turned liquid beneath me. I thought we were gonna die, get swallowed up by a crack or have the roof cave in on us. Even though the entire thing lasted over 30 seconds (long by earthquake standards) we were frozen in place, unable to move or walk. We found out later that the quake registered 5 something. On reading all this, I flashed back to that day and felt a panic rising inside me. Even though the Northridge earthquake was much stronger, I've never felt one scarier than the one I felt in Visalia. Nothing even fell or broke.

Someone asked whether Mt. St. Helens and the earthquake could be related. Absolutely. I'm sort of an amateur geologist, have been studying the stuff for decades....I've concluded that periods of high precipitation followed by great heat (that's September in the Central Valley for you!) seem to cause more earth movement. A volcano is fed by underground magma pools, when one erupts or emits steam or anything that causes it to give out materials inside, it creates an empty cavity, releasing pressure, allowing movement. The huge Mt. St. Helens eruption in 1980 was preceded by an extremely wet winter, and followed by a rash of many over 3.0 earthquakes.

Don't worry unduly, hardly anyone dies in an earthquake. Remember, without earthquakes there wouldn't be the Rockies, the Sierras, Cascades, etc.......

Its bizarre watching more and more earthquakes show up each time I refresh the screen on the first listed website.

Hope things turn out OK

I wanna see the ground give way.
I wanna watch it all go down.
Mom please flush it all away.

Learn to swim.
