Shake, shake, shake them bones.
 

Or cities.

Earthquake!

Rock and roll, L.A.

When it started, I really expected it to be bigger. If felt like the beginning of something big but as soon as it began it was over.

Shake that booty, L.A.

Magnitude 3.5

(Felt like more to me)

5 km (3 miles) ENE (57°) from Yucaipa, CA

Short, but strong. 5.3. Seems to be a separate quake, not an aftershock. Although it seems to have tirggered a 2.4 aftershock at the site of last week's. There was a 3.5 immediately after the big one (I think I felt it...either that or my legs were still shaking), and then a couple 2.2's

Oops. It's been upgraded to a 5.3. That sound about right.

The 3.5 was an immediate aftershock. The main quake was 5.3

Oh, the nausea of a building on ball-bearings. We're still gently reeling. Workday earthquakes are the most motion-sickness I ever feel.

Anybody we know near Yucaipa?

The initial report on the main quake was 3.5 which was then upgraded to a 5.3.

Often far more damage can occur in a smaller earthquake of prolonged length than a larger earthquake of shorter duration, so I'm glad this was short, considering that it was also moderately large.

I won first prize in my 6th grade science fair doing an earthquake study. I was such a little scientist, but that was it for my career. No becoming a robotics engineer for this girl.

The house kitty-cornered from ys is getting a new roof. The bet those roofers had a ride!

Is everybody OK down there?

btw---just what is it like to be on Big Thunder durring an Earthquake? Can you even tell?

I didn't feel it.

We figure we were on Splash during last week's earthquake. Didn't feel a thing.

Phooey! I tend to feel things that no one else around me feels. I have not felt any of the recent ones, I was either too far north or too far south. The last 3 or 4 I felt I had to prove to others that I am not just being dizzier than normal and that there was really an EQ.

I am such an unfeeling soul, it's no surprise that I did not feel so much as a tremor of this recent purported "quake."

But as for being at Disneyland during an earthquake, I'm informed that the quake caused the shutdown of Pirates, Indy, Haunted Mansion and Big Thunder. Probably internal sensors, but maybe something a little more juicy?.......

longjohns, anyone?

Hmm, now they've downgraded it to a 3.7

Or 4.9 if you want to believe this site instead.

It was one of those abrupt jolty ones (versus the rollies) for me here in the South Bay. A couple of picture frames did fall off a high shelf.

I was driving. Didn't feel it.

Started to question things when Indy, Pirates, and Mansion were all closed and overheard the word "earthquake" and "5.3?" in several conversations.

Anything under a six isn't a real earthquake.

Is it my imagination, or does there seem to be more quakin' than usual going on along the Pacific Rim?

After a gigantic shift like the one in December, it's not surprising to see a little more activity for a while. I mean geez, it affected the rotation of the earth.

Y'all just make sure you keep it down there, y'here?

Sho 'nuff

I was standing behind my table at the Century City Farmer's Market and thought, "What the hell was that?" Nobody walking around me reacted at all, a short time later I felt another, and decided to call KNX newsradio to find out what was up. They very kindly put me on hold so I could listen to the news. Weird, short, bumpy earthquake. Me no likee earthquakee.

I was on the comp playing WoW, and was like, wow, an earthquake. Yawn.

No, no, no , no, no! You were supposed to reply " Everything is normal- nothing unusual happening here". Remember, I'm flying, which I hate to do, down to DL, and if there is one thing I hate more than flying, it's earthquakes. Good thing I have my priorities straight and I love DL more than I hate those other things.:rolleyes:

Btw- only one month to go!!!!!:D

Well, see, that's a good thing. If you're flying, earthquakes won't matter.

Whoa, anyone notice that there was just a 6.4 in the ocean, right near where the 7.2 one from Tuesday was? It was at 10:20. Meanwhile, Yucaipa and Anza are busy ping-ponging mid-2.x quakes. The whole state's a quivering mess right now.

Well technically, every time I jump up and down it effects the rotation of the earth to some small degree. Errr, umm wait a second, that does not sound quite right. What I mean is even small events like a meteors effect the rotation of the earth to some degree, I don't think you can automatically argue that the recent Cali Quakes (great name for a rock band by the way) could be linked to the Indian Ocean quake. Hard Facts, Hard Science. Show us your scientific evidence for such claims or do the mambo-dance of shame for spreading unsupported scientific rumors.

Okay, it significantly affected the rotation of the earth. Based on calculations, it's shifted the location of the north pole (I don't know if they geographic north or magnetic north) by about an inch, and sped the rotation of the earth up such that a day is now a little more than 2.5 microseconds shorter. It changed the shape of the earth, making it slightly more round (a greater trend, apparantly).

Yes, all earthquakes have these kinds of effects to some small degree. But this one's effects were noticebly measureable.

Geez, if these keep up, you're going to make last year's hurricanes look like nothing. ;)

Oops, forgot the links.

I like this stat:

More of an effect than the sudden appearance of 10 trillion gallons of water would have. I'd say that's significant.

*swoons at GD's feet*

Nope sorry, nice attempt at misdirection but I'm not going for it.

Yes, the Indian Ocean quake had a measurable effect on the planet but that is NOT the issue here. The issue here is:

Please support your theory that the Indian Ocean quake had anything to do with the recent increased activity in Cali. Nothing in either link even suggests such a relationship. So show me the money, or let's see that dance :)

It's a little theory I like to call "Plate Tectonics." A major plate moved 30-55 feet in December. That's ridiculous. That's the kind of movement that generally takes centuries of "normal" earthquake activity to produce. And it's not some isolated system. Even though it was a quarter of the way around the world, all of these plates are interconnected and every movement affects those around them. Most of the time, that affect is miner and part of the general cycle of things. But a 9.1 quake HAS to have some far reaching affects.

Look at the earthquake activity since yesterday's Yucaipa quake. Specifically, look at the area around Sunday's Anza quake. Since the Yucaipa quake, the Anza zone has been more active. Rather, it's been the same frequency of shaking but with more intensity. Since Sunday, there have been a steady stream of small quakes, most of which have been below 1.5, the largest being 2.6. Since yesterday, the frequency of temblers >1.5 has increased, and there have been several of 2.6 or greater, including a 3.4.

Yes, it's circumstantial, but it doesn't take a whole lot of research to say "If this hunk of rock over here moves, and it's a) touching this other hunk of rock and b) causes this other hunk of rock to shake, then there's a good chance this other hunk of rock is gonna move too." And the recent activity supports that. Nevermind that whenever there's a large earthquake, almost invariably they are followed by increased activity on surrounding faults, even if those faults aren't directly connected to the fault causing the initial event.

Okay, so we have some evidence in a small area that larger than average earthquakes affect activity elsewhere, albeit somewhat geographically close. Now, yesterday's quake was a 4.9. The Indian Ocean quake was a 9.3. The scale is logrithmic. Every full point on the scale is a magnitude of 10 increase in strength. So, doing the math, the tsunami-inducing quake was 40,000 times stronger than yesterday's.

Definitive proof? No. But I stand by my statment. It's not surprising.

:jumping on the GD bandwagon: I'm not surprised by seismic activity after other seismic activity. No more "wow" factor. Now, I would be surprised if fire rained down from the sky. Were you surprised to find out that Anakin Skywalker was Darth Vader? Probably not, but what if they had done a switch, and it turned out that Jar-Jar Binks was Darth Vader? Bet you'd be surprised then! Oh, and the rotation of the earth stuff? Yeah, yeah, whatever. Had to reset all my clocks.

Some support for the phenomenon on a local level. It's a BIT of a leap to extrapolate to a global level, however, once again, we're talking about an entire plate moving 30-55 feet, whereas the affect mentioned above is caused by the simple movement of a foot or less of small portions of a plate. So it's not all that out there to theorize that this effect would scale to many orders of magnitude in scope with earth movement as extreme as that.

Very good. Case closed.

Linky linky, I got more linkies!

OK, looks like I went a bit over the top with this one and got stung for it. Ouch.

Yes, I was just kidding around for god sakes. Of course it's possible the earlier quake effected things in Cali, which is all the origional post ever implied. I just ran with that. Apologies to one and all if it came our diffrently than I typed it.

GD should quit his day job and become a full-time fact finder. :snap: As a fauxbrarian, I'm very impressed.

GD, I bet you got beat up a lot in Elementary school.;)

(Just kidding!!!)

(I hope you really didn't!!)

Jr. High

Unless of course the earthquake destros the runway you were planning on landing on!

Ouch

By elementary school kids no less

(tee hee)

C'mon now! They were BIG 4th graders. ;)
