Wow, we just got an earthquake here in Oakland

[jannyk]

a good shaker - guessing a 4-5. Anyone else get awake up call?

[ourbluenation]

1. didn't feel it here in the north bay but hey - your one post away from 1000

[Demobrat]

2. I'm right across the bay in SF.

I'd guess about that.

[Auggie]

3. Didn't feel it either (Napa County)

[Mz Pip]

4. I felt it!

My house rattled. Checking the listings - 2 miles ESE of Berkeley. Magnitude not listed yet.

5. yep.

Wow, you're fast! Got a good jolt didn't we?

[Greyskye]

12. Welcome to DU!

[Starry Messenger]

18. Thanks!

I'm a longtime lurker. But now maybe being into double digits on my post counts will give me a boot of confidence!

49. 3.4 is nothin'..............unless you happen to be sitting right on top of it.

[MsKandice01]

9. I didn't feel anything here in San Jose...

But I was up in Oakland a couple months ago when you guys had 3-pointer. It looks like the one you just felt was a 3.4 right underneath Berkely.

http://quake.wr.usgs.gov/recenteqs/Quakes/nc40193843.htm

[Demobrat]

11. Damn you guys are quick!

3.4 is just a little guy.

[EFerrari]

13. I felt something out here on Ocean Beach in SF.

Damn. I hate not knowing if that was IT or not. :(

[fooj]

22. I hear you...

I was "red tagged" in '89. That's the scariest part of these damn things. You never know if one will follow that's MUCH larger...

[MsKandice01]

27. Yeah, that's always what bothers me about the little ones too...

The shaking doesn't scare me, it's the thought that it could be a foreshock to a larger one that always gets me.

[EFerrari]

30. Exactly. I don't mind dealing with earthquakes but you never

know if you are looking forward to worse or not. :(

[Pastiche423]

56. OMG. Were you able to save anything?

I was in the crowd in the Marina Middle School parking lot when they were giving out the red, yellow and green tags.

[fooj]

57. Marina? As in next to Seaside?

Sounds like you may be a "neighbor"...

Unfortunately, I lost ALMOST everything. At least I'm still here. B-)

[Pastiche423]

61. The Marina District of SF

was where I was. The fires were still blazing when my next door neighbors and I tried to help some people that were redtagged the next day.

I no longer :cry: live in SF. Can't afford it, but my heart will always be there.

I am so glad you are still here! :hug:

[fooj]

66. Me, too.

:hug:

[B Calm]

14. nothing here in Indiana..

[EFerrari]

15. . . .

:spank:

[B Calm]

23. Hey I remember having an earthquake here before..

[B Calm]

26. Largest Earthquake in Indiana was a Magnitude 5.1

http://igs.indiana.edu/geology/earthquakes/eqinindiana/index.cfm

[EFerrari]

35. Well, I hope it stays a memory for you, B Calm.

:)

[SoCalDem]

55. You're laughing, NOW,,but hold on tight if the New Madrid fault kicks up its heels again..

You might feel that one,.. even in Indiana

[tinfoilinfor2005]

59. I've been to Indiana.

You nailed it.

[sellitman]

72. lmao!!!!!!!!

Good one!

[Fresh_Start]

16. only 3.4

we'll live another day

[EFerrari]

17. I guess it "feels" bigger out here on the beach. All my cats

sat straight up. :shrug:

[Fresh_Start]

20. The big ones continue an eternity

Or at least it feels like an eternity.

Count how long you feel the shaking. I didn't even get to 3.

[Mz Pip]

24. Mine didn't

lazy critters.

:dem:

[originalpckelly]

39. Da widdle putty tats!

:loveya:

[originalpckelly]

36. Actually, you're exactly right. The beach is not stable...

and in fact the unstable ground beneath San Francisco is what caused the 1906 quake to have such a devastating effect.

[EFerrari]

43. It's like jello out here so I have to factor that in every time. n/t

[slackmaster]

19. Looks like it was right on the Hayward Fault

Time to call friends in Montclair.

[MsKandice01]

25. I truly hope that wasn't a foreshock...

When the Hayward Fault finally goes again, it's gonna be NASTY.

[EFerrari]

33. Yep. And the UC Regents will have two crescents on their hands

where a stadium used to be. :(

[slackmaster]

45. I Google Mapped to the coordinates

The reported epicenter is about 200 yards east of the field.

[EFerrari]

51. Hayward fault runs right under it. Of course, in CA, that's how you find

faults.

You look for hospitals and schools and other large public facilities.

[wryter2000]

38. It was probably 6 miles from Montclair

I used to go to school at Berkeley and live in Montclair. It's about 6 miles. I was 4 miles from it. I imagine Montclair didn't get any more than I did.

I sure felt it.

The USGS says it was 3.4 in Berkeley. Actually, right on the border with Oaktown.

[sakabatou]

32. Nothing here

in Silicon valley

[jannyk]

34. It may have been only a 3.4, but it was right under my butt

I've lived in the Bay Area 30 years - so I know what big ones feel like and usually a 3.4 would pass without notice. If not noticed 4's before, but this one was a real 'shaker'. Not a 'roll', not a 'lift' but a really violent 'shake'. Lots of noise and major rattling of windows and stuff in cabinets. A glass fell off the kitchen counter and the stuff on the walls is all askew.

Those that have lived here a while know the feeling, you sit there, hold your breath and wait for it to get worse or stop.

My dog has been 'anxious' all day - wouldn't settle - being a right pain in the arse. He went wacky during the quake - howling and whimpering.

If you look at the shake map - you'll see most areas have it pegged as 'feeling' like a 4+.

[EFerrari]

37. All my guys have settled down. I hope that's an indicator. n/t

[jannyk]

44. Yeah ,I'm headed over to Home Depot in Emeryville...

can just imagine being squashed by ten ton of shit falling off their shelves :eyes:

If I go missing - that's where to look for me. :hide:

[EFerrari]

48. Home Depot wouldn't be a bad place to be in an emergency.

Be well, jannyk. :hi:

[wryter2000]

42. Wow, you must have been right over it

I got a definite shake and noise. Just enough to make me wonder if I ought to do something. Then, it was over. Nothing fell. The blinds didn't slap against the windows.

[originalpckelly]

47. It's all about the soil. SF has the absolute worst kind of soil for an earthquake prone area...

it's very unstable and it liquefies when it is shaken. That's why the 1906 quake was so bad.

[jannyk]

50. Yes, but I'm not on fill - I'm on the top of a hill

Grand Lake Heights on the Piedmont border.

[Auggie]

60. Not all of San Francisco is built on landfill.

The Financial District, the Marina, and parts of SoMa are the most vulnerable.

[EFerrari]

69. Well, some people think the Richmond and the Sunset will

liquefy if the San Andreas goes.

[Auggie]

71. That would be catastrophic.

[Cessna Invesco Palin]

76. I used to live out in the 20th & Taraval area.

Down by where the L-Taraval crosses 19th. I felt a couple of earthquakes while I was living there that weren't felt by some friends of mine up the street in West Portal, quite a bit of which is on bedrock. West of 19th is mostly built on sand. I have no doubt that the whole thing would liquefy in a major quake. The consistency of the sand and the moisture content make it almost inevitable. Not the best place to build block after block of soft-story row houses, but that's what's been done.

[EFerrari]

77. My neighbors played a documentary for me that showed a model

of the Richmond and the Sunset becoming really ugly oatmeal. And here we sit. :shrug:

I'll have to ask them who did it because it did a lot of debunking about quake v. fire in 1906.

/oops

[karlrschneider]

40. Hope that's as bad as it gets. Oddly, we have been getting many quakes in OKLA

the last couple years (???) smallish ones, 3 to 4 but they are putting out seismometers out around to get a better picture of what's going on. Weird stuff...

[proud patriot]

41. I wonder if that's why the dogs woke us up

I just got home from work and didn't realize there was a quake

[EFerrari]

46. Here, it felt like a really Big gust of wind until

you realized that our winds don't do that. And all the animals woke up and came and stared at me.

lol

[proud patriot]

52. LOL

That's what our dogs did ..I woke up to doggy breath
thinking that they had to go potty...

:shrug:

[EFerrari]

53. LOL! Life at the Edge of the World.

:)

[musiclawyer]

54. Just a matter of time before Hayward fault blows

Then all those beautiful million dollar houses in the Oakland Hills overlooking the golden gate might not be worth as much. We choose to live where there is beauty. But where there is beauty nature always takes its toll.

[Clark2008]

58. No offense, but...

An earthquake in Oakland rates a "wow!"?

I thought that was pretty standard faire and would be more of a "ho-hum."

:hi:

[EFerrari]

62. Well, no.

[jannyk]

63. Not if you were right on top of it

as I was.

I have lived here 30 years and been through many, many 'quakes - including Loma Prieta. Bigger ones than today's have occured without my noticing. It often depends on the type of movement - some are gentle 'rolls' - some lift everything staight up in the air and plonk it back down hard. This one today was a violent 'shaker', was within 3 miles of my home and rattled, shook and moved a lot of stuff around - that's not 'standard fare' or 'ho-hum'.

You're right in that most times they don't even rate a mention - this one - especially in my neighbourhood - was more violent than any I've felt in years. One of my tenants, recently arrived from Florida, was in tears - she'll have to toughen up and get used to it.

[slackmaster]

64. The concern is that it could be a foreshock of an expected catastrophic quake

On that particular fault.

When the ground starts moving, you always wonder whether it's going to stop soon or keep getting bigger.

[EFerrari]

65. It's never really "over" and that's the hard part for me, anyway. nt

[slackmaster]

67. The first big one I felt, in 1968, had a significant impact on my life

I was 10 years old. The experience has led me to be prepared and independent. I got interested in backpacking and learned survival skills. I keep supplies of non-perishable food, drinking water, etc. on hand at all times.

Yes, it's never really over, just a matter of when the next one will hit, where, and how bad. I'm prepared to survive at home without any assistance for two weeks.

[EFerrari]

68. Me, too, except we keep drinking the wine, smokiing the cigs

and spending the bribe money. lol :)

[Adelante]

70. When I lived in Berkeley in the early 70s

I was tossed out of bed by a small one. For a native New Yorker, it was HUGH!1!

[EFerrari]

73. I was a few weeks from being smooshed on the Cypress structure

which pancaked in the Loma Prieta earthquake. I'd been commuting from Berkeley to the South Bay and used to hit that part of my commute right around 5 o'clock. A few weeks before the quake hit, I went back to school.

My house slid on its foundation but the alternative always seemed worse to me. :scared:

[Adelante]

74. EEEEK, I'm glad you missed it

:pals:

[EFerrari]

75. What's funny is that I never felt good on that stretch of road.

Some days, I'd take a detour rather than get on the structure even if it meant my two boys would wait an extra 30 minutes for me to get home. It was just creepy. Whatever. It's not there anymore; they didn't rebuild that death trap.

I guess I should thank the Graduate Department for taking me in and saving my life. lol

:pals:

[Auggie]

78. Prior to 89, the only double-decker freeways in CA were in the Bay Area.

All four were severly damaged in the Loma Prieta quake. Only one remains - the other three were torn down.

They all made me feel creepy. As does the Caldecott Tunnel.

[EFerrari]

79. After the Oakland fire, the Caldecott doesn't seem like a great idea

does it?

I had lots of friends who had to evacuate.

[Auggie]

80. There was an accident in there in the mid to late 70's -- a fuel tanker

and a car, I think. It ignited the fuel and torched everything in the tunnel. A bus of AC Transit riders were burned to death, among some motorists. I wasn't living in the Bay Area at the time so don't really know the details. You'll notice a sign heading westbound on 24 that says something like no trucks carrying flammable materials are allowed to enter unless it's really late at night. That's why.
