[EFerrari]

Anybody have info?

My whole building shook and waved and it was THAT far away?

We have no local news. Cats aren't happy. Shit. Doug is at a gig and we have 8 animals.

I'm going to go check my neighbors.

:(

[Book Lover]

12. Stay safe

Hope all is well!

[EFerrari]

22. Thank you, Book Lover. I'm sure it's okay. You just never

know when the thing is over. Faith based California living. :)

[TahitiNut]

55. Here's the Intensity Map (will be current when viewed)

[Union Label]

76. Ho-Hum a 4.5 isn't worth waking up for

A Non-event.:boring:

[Duer 157099]

2. No, but I sure as hell felt it!!

[LeftCoast]

3. It's not up at the USGS just yet.

[Redstone]

4. I'm sure it gave you a case of the willies, but if nothing broke,

you're OK. At least for this time.

Redstone

[EFerrari]

30. I checked at the little grocery store across the street.

There is no milk in the aisles.

:)

[redacted]

5. We really felt it here in Santa Rosa. long and rolling

[cally]

9. It was long and rolling for you??

Wow. I live in Marin and we felt a quick jolt. Something in the geography must have changed the effect.

[redacted]

15. Yeah it went on for 7-8 seconds. Rumbling.

[Duer 157099]

16. it was centered up here more (a few miles e of Santa Rosa)

[redacted]

17. I heard Glen Ellen, we are near the creek (which is a fault) so

maybe why it was long and rolling here.

[EFerrari]

25. Geology but also the type of structure you're in.

I hope everyone is okay. :hi:

[cally]

6. Weirdest one I've ever felt

I thought something had hit my house since it was so quick. The hanging lamps stayed still. Weird.

[Hell Hath No Fury]

54. Hey Cally!

Glad to hear you're okay up in Marin -- when we ahve these, I'm always afraid that what I felt is just a small bit of a much bigger quake somewhere else. :scared:

I'm up on bedrock in SF in a wood house and this puppy was really going! Enough for me to get up off the couch and get to my hallway. :)


Hope all is well with you and your family! :hi:

[JI7]

7. based on the posts , it must have been a really big one

i hope things are ok. i expect breaking news on this soon.

i'm in Los Angeles and didn't feel anything.

[DoYouEverWonder]

8. At least two other threads have popped up

Sounds like a lot of people felt it.

[w8liftinglady]

10. whoa!are you guys ok?

[redacted]

23. Yeah, ok, just shook up; dogs a little upset

mostly because it delayed their dinner.

Nothing on XM's emergency channel yet; wonder if they'll cover it?

[JI7]

11. for those who felt the quake, how long did it last ?

was it a shaking type of quake or more of a rumble ?

[Duer 157099]

14. It was long

first a sharp knock, then a sustained rumbling

my heart is still thumping, waiting for the ... ??

[EFerrari]

39. That's the part I don't like as well. Is this the beginning, the end,

the throaty middle, what?

lol

Well, it looks like we okay. Whew.

:)

[Duer 157099]

47. Yeah - after the first few seconds, I had flashbacks to

Northridge 1994 (was 4 miles from the epicenter), and 1971 Sylmar quake.

::shudder::

And here I thought I was safe in Nor Cal ... lol (no, I really didn't)

[EFerrari]

49. My brother was IN Northridge and he still has flashbacks.

I was in Berkeley during Loma Prieta and my house slid on its foundation.

So, no PTSD here at all!

lol

[Duer 157099]

56. Yeah, the worst part is from having gone thru bad ones

Otherwise it might be a little bit fun!

[EFerrari]

62. Thrillseeker.

lol

Arms,legs,cats, check. :)

[BrotherBuzz]

40. Solano County - 35 miles from epicenter

just two minor knocks/rocks two seconds apart.

[LeftCoast]

13. Looks like it was a 4.5

Centered in Glen Ellen in Sonoma.

[Blue_In_AK]

26. We had one here last week

about that strength, almost directly under Anchorage. It woke us up at 5:30 with a good jolt ... it felt stronger than it was because it was so close.

[LeftCoast]

32. I bet it felt pretty strong! I'm about 60 miles from this epicenter

Going to have to call my friends in Santa Rosa and see how it was for them. They're much much closer to the epicenter.

[Blue_In_AK]

43. Well, it did wake us up

and I generally sleep right through them. They're such a common occurrence up here that it has to be a pretty good one before it makes my heart race. The last really good quake we had was in November 2002, 7.9 centered a couple hundred miles north of here. Ironically, I was in California at the time, but my kids said it was pretty exciting here. No damage in Anchorage though.

[pinto]

18. USGS hasn't posted it yet. They'd appreciate input on the

"did you feel it?" section of their website.

Cut 'n paste of their 20:00:03 PDT map:



Report an Earthquake:

http://earthquake.usgs.gov/eqcenter/dyfi.php

[EFerrari]

41. Thanks, pinto. I love that site. It's smart and helpful.

The government isn't both very often. :)

[Cleita]

19. Keep safe and take care of yourselves.

:grouphug:

[LeftCoast]

20. Hey, sfexpat2000 what part of town are you in?

I'm on granite. I live on Mt. Davidson, so it wasn't too strong here.

[EFerrari]

27. I'm on the beach in the tsumani zone.

My cats are still freaked out and watching.

I use them as predictors as the Chinese use chickens. :)

[LeftCoast]

29. Did the cats freak out before the quake?

My dog barely even noticed it as it was happening. :)

[EFerrari]

31. No! The little bastards! Sleeping on the job!

lol

They're still not very happy, though.

:hi:

[xchrom]

21. i'm in oakland and it rolled here pretty good.

[Gormy Cuss]

24. Very mild on east of the tunnel ( WC/Pleasant Hill area)

I felt the little 'bump' after the roll but both were very mild.

[EFerrari]

28. Good. It was pretty nasty here but not for very long. I hope I didn't

scare any one.

[Gormy Cuss]

33. I love DU for earthquake reporting.

We have enough posters around the area to get a reality check on the quake intensity even before the USGS!

Sorry you had the good jolt -- I know how unsettling those are!

[EFerrari]

35. Uglies! And if it weren't for DU, I would have had 15 minutes to

prep for the last tsunami warning. Because, lol, no one was minding the FAX MACHINE at the Hall of Justice.

:rofl:

[redacted]

37. Scared me. It went on for so long I thought it was a BIG one somewhere

else.

Rather than here in my backyard. :-)

[EFerrari]

46. Please tell your backyard to hush up and go to bed!

lol

[proud patriot]

51. I live in the east bay and didn't feel a thing

I wonder if I was in the car when it happened

[EFerrari]

52. Good!

:)

[davidinalameda]

34. I'm in Alameda and it was okay

:hi: neighbor

[EFerrari]

36. Hey, dwickham. What about Pachamama?

Darn. I really don't like those things. :hi:

[davidinalameda]

71. what's Pachamama?

:shrug:

[EFerrari]

72. LOL! I may have the user name wrong but she posts in the CA

forum and I believe may be closer than I am to the epicenter.

You made laugh. Thank you!

:)

[Patsy Stone]

38. Everybody okay?

:hug:

[EFerrari]

42. Looks like it. I've nothing on the teevee yet. Darn this consolidation.

Really, the nasty part is wondering if this is the first or last shaker. My cats are not happy.

On the other hand, maybe they're just trying to psych me out.

Thanks!

:hi:

[Patsy Stone]

48. Maybe the news stations

thought you didn't even notice it? :eyes:

Yep. I could see how that would be an unsettling feeling; are there more?

Cats live to psych you out, but I'm sure they're not happy about it anyway -- regardless of their little mind games. :)

Glad to hear all is well!

[EFerrari]

50. Nothing more. It's like being dumped after the first date.

:)

[MzNov]

44. Didn't feel it in Palo Alto, but San Jose people did

I heard 4.7, is that right?

[EFerrari]

45. Sounds about right. Iirc, the network of faults go around Palo Alto

that's why your real estate appreciates so well.

My mom in the E San Jose foothills has two faults / creeks that runs up through the ranch. She probably felt it more than PA did.

Man, from excitement like this, I'm not needing. :)

[MzNov]

57. wish I could afford real estate here... argghhh

I wish I would have felt it. Haven't had one for a while. :-)

[EFerrari]

59. Here, have some of mine!

[zulchzulu]

53. Make sure you update your Quake Pack...

I used to live in SF (lower Pac Heights) and realized when I moved that I had botulism in a couple cans of stuff and pretty old water...

This one sounds like it wasn't one of those coolio mushy kind...I always hated the sharp bangy kind...

[EFerrari]

58. Definitely! After Katrina, I put in a 2 week sheltering in place kit

AND a "to go" kit. But we keep filching from the cache of cigs and cash. Oops!

[Swamp Rat]

60. Are you OK?

:hug:

[EFerrari]

61. Yep. We're cool, Swampy. The cats are still on Red Alert

but maybe they're just messing with me.

Ack.

:hug:

[Swamp Rat]

63. So you were able to get them down from the ceiling?

:D

I experienced a 5.5 in Salt Lake City many years ago... scared the crap outta me! :scared:

[EFerrari]

67. One of them is still up there.

LIHOP? MIHOP?

:rofl:

[Duer 157099]

64. Aftershocks

Here's the list -- I haven't felt any of them (I'm about 9 miles from the epicenter).

The good news, I think/hope, is that the aftershocks are smaller, so this wasn't a foreshock (that's ALWAYS my first thought)

MAP 1.5 2006/08/03 04:25:43 38.359 -122.582 7.7 4 km ( 3 mi) W of Glen Ellen, CA

[EFerrari]

68. I was so scared I forgot the most important question --

will the wine be okay?!

:scared:

[Duer 157099]

77. It'll be fine. Shaken, not stirred

:)

[Warren DeMontague]

65. Wow. I'm surprised everybody felt it as far away as they did.

We're in Sonoma county, and definitely felt it- it certainly got our attention- but I didn't think it would be shaking folks down in the South Bay, for instance.

Phew!

[EFerrari]

69. Depends if you're plugged into the "nervous" system of faults

My mom did feel it, in the SJ foothills. Her horses are spooked.

I felt it on the SF beach -- which isn't surprising when you think about it.

I miss smoking pot on these nights. lol

[savemefromdumbya]

66. Ow! Hope everybody in SF and surrounds is OK?

[EFerrari]

70. It was centered up north of us -- I probably felt it more because

on the beach.

Looks like everyone is okay, thanks!

[LeftCoast]

73. I think so. I'm only about 3 miles from you, but I live on a Mt.

Really wasn't a big deal here. You could feel it, but it was just a little shiver and then a roll and it was over. Granite is a good foundation!

[EFerrari]

74. My poor cats are still not calm. The building did exactly what

it was built to do -- it shook and swayed really well. :(

Check the CA forum in the a.m. I was going to post a notice for DUers there tonight but I think I need to settle some furry guys (and me) tonight.

Take care, neighbor.

[LeftCoast]

75. G'nite!

Take care!

:hi:

[sakabatou]

78. I felt nothing

[EFerrari]

80. Good!

:)

[EFerrari]

79. But enough of our shaker -- check out these 2 DUers confronting

racial profiling.

:smoke:

[craychek]

81. was in california for the 7.0

That was scary. 4.5... not so much. I was in cali for a 4.something as well before I left for nebraska for school. Honestly, after 7.0 everything else seems to be gravy. It's the only time in my life that I almost passed out. after that I've never even come close.

[EFerrari]

82. This is my first quake here at the beach, and have to say,

4.5 on this sand felt like Loma Prieta did when we were in Berkeley -- what was that, 6.something?
