Rocking and rolling in SF

Very true. Sort of like us with Hurricanes.....you can't stop them so you learn to cope.

Maybe they were covering the drill? If you find out anything let us know ok?

I'd rather ride out a hurricane any day than deal with an earthquake! I'm near a shakey area now, but came from the SE coast, so it's probably just a getting used to it thing!

You and I both.....I would be seriously scared if the ground started shaking under my feet.

Another EQ, same location about 1 hr ago. 4:50 Local Berkeley time.

Mag: 2.2

JUST now had another short shaker

waiting on Mag

Yet another one! This one was closer to the size of the afternoon quake -- I'm guessing around a 4?

We just had another, this one felt like a normal shaking, if there is such a thing lol.

earthquake.usgs.gov...

The Haywood is the last one we want to get active it's way overdue.

Yup, Hayward is active again, looks like same spot, same depth, no info on mag yet . . but definitely longer in durration than this afternoon . . .active afternoon / evening in SF!!!

It actually felt like it was going to build but then it suddenly stopped, I was grabbing my stuff lol. (no not that stuff)

so, the one this afternoon was a foreshock


I am a little afraid now that we may see a bigger one

reply to post by berkeleygal


They're getting bigger, that is not good. Mean these could be precursors right?

Hmmm so we're thinking alike?

Oh my!!!!!
Another one!
Earlier was a 4.2 and now a 4.0! I'm scared about what might be coming next....
With if these are all the foreshocks leading up to a 7+......
It's totally plausible. I won't be sleeping well tonight

reply to post by QuantumPhysicist


you got it backwords,,, the first one today was the 4.0 and this was 4.2

Oh lawdy! I gotta sleep in my shoes tonight!

eta

now they have dg'd it to a 3.9

There was an earthquake drill today, it must be HAARP lol.

reply to post by QuantumPhysicist

It's almost exactly the same as earlier. Same initial magnitude, same downgraded magnitude...almost the same depth, almost EXACT same area.....

Seems either they are accidentally reprinting the event from earlier or something did actually cause this and is doing it again....

IDK...but honestly...you don't see the exact same location or depth ever...they are almost always both even just a little different than previous ones.

4.0 2011/10/20 21:41:04 37.856 -122.253 8.2 3 km ( 2 mi) SE of Berkeley, CA

3.9 2011/10/21 03:16:05 37.869 -122.252 9.6 2 km ( 1 mi) E of Berkeley, CA

getting closer to me

another day, nothing major... I wonder how the drama queens in SF will react to this.
