When the 3rd one happens, bend down put your head between your legs and

Better than one earthquake twice as strong.

The third one just happened -- substantially less energetic than
the two before...

I take this as a good sign that the fault in question is easing
before it needs a massive rip (and given that the epicenter is
about a mile from me, that is a relief).

The third one felt smaller, but it was 3.5 (the first two
being 3.7) so not smaller by much.

All exactly the same geolocation.

Yep; I checked that shortly after I wrote. But note that 2/10
on the Richter scale means that the 3.7 quakes were about 60%
more energy than 3.5.

Only time will tell if these are still foreshocks.

Yes, at least one of the three identically-located quakes
was reported as being a quake in the Hayward Fault.

And A geologist was reported as saying the three quakes
could be just a coincidence. Unrelated to each other.

Ahhhh, they're just babies!!!


I was slap dab in the middle of the 6.7 in LA in '94.

There were *thousands* of aftershooks in the following weeks all
registering in the 4.0 - 5.0 range.

There waz some rockin' and a rollin' going on then!!

Qutoing from:
http://en.wikipedia.org/wiki/Hayward_Fault

Since the 1906 San Andreas event there have been
no moderately strong earthquakes on the Hayward fault
as were seen before that earthquake. It also appears
likely that this quiet period in the earthquake shadow
is ending, as projected by the rate of plate motion
and the stress state of other faults in the region.

The following table chronologically lists all of the
historic earthquakes on the Hayward Fault Zone which
have exceeded magnitude 5.5. No earthquake of that
magnitude has occurred in the 20th or 21st centuries.

and . . .

Of all the region's large faults, the Hayward + Rodgers
Creek fault system is considered most likely to create
the next major destructive earthquake in the region.
Less-destructive earthquakes have been occurring in the
region at random 15 to 30 year intervals - typically
causing spillage of merchandise and occasionally,
structural failures in lower stories and chimneys.
This type of event is considered normal in California's
"Earthquake Country" by geologists and long term natives,
although disquieting to recent immigrants to the region.
A major event on either the Hayward or San Andreas could
produce a minute or more of intense shaking, as was felt
in the Kobe earthquake.

and . . .

A recent quiet period following many years of minor activity
is considered to be particularly ominous by many, although
geologists have not yet been able to predict earthquakes
with any useful accuracy.

A common misconception is that several small
earthquakes can somehow defuse or postpone
a more devastating one. Alas, it doesn't work
that way. Since every step up in magnitude
represents a 33-fold increase in a quake's
power, a 7.0 actually releases 1,089 times
(33x33) as much energy as a 5.0. At the
same time, each step up the scale represents
a tenfold drop in frequency of occurrence --
5.0 quakes, in other words, are a hundred
times more common than 7.0 quakes, but more
than a thousand times weaker. "If I wanted
to avoid a Loma Prieta magnitude 7 by knocking
off magnitude 5s, I'd need a thousand of them,"
Stein says. "If I wanted to do it with
magnitude 3s, I'd need a million of them.
We don't get that many small ones. You

Yeah, we're due for a huge one here in the PNW as well. My house is
stucco so we are screwed. 'Quake insurance only covesr 90% of the
value of the structure, and you have to pay 10% up front. For us
that's a huge chunk of change we'd have to cough up pretty quick.
Better than no quake insurance at all, but it sucks.

One major reason I stopped watching the news. The formula,
report on some event, then without fail, could it happen here?
Is a worse (whatever) right around the corner?

About 10 years ago, newspapers quit using proofreaders who

To be fair, they're under enormous cost pressure and have

The other day there was a headline, $705,000 robbed.

So ... was the $705,000 shaken up after that scary event?

I'm fairly disgusted with my local paper's food section. They use a
local woman (The Augusta Chronicle and Karen Calloway) to do a weekly
article on simple food preparation. Perhaps a bit too many "convenience"
items so she borders a bit on Sandra Lee, y'know? I just about blew a
gasket when she had a recipe for pasta e fagiole....but called it "The F
Soup"!!! What the hell? If *she* can't pronounce it, she could have
researched it and shared with readers how to say it properly and done
something of a service to her readers. I was so annoyed by the "dumbing

Did you write to her, Goomba? I woulda. I've also written to my

an articulate kook (most of the time!)

LOL! No, I never hear back either, but the mere writing of it makes
me feel better. The day NPR goes south, grammar-wise, is the day I

well-spoken. In this country (USA), anyway.

I've had this bookmark for a couple of years:

They've changed the format a couple of times, but the link seems to

Then he is not much of a geologist.

Earthquakes are the motion of material in and on the earth's crust.

Move the two sides of a fault, and, you alter the stresses that affect
the likelihood that another fault nearby or another part of the same
fault will go from static friction to kinetic friction.

Three earthquakes close enough together that you can't resolve them as
separate locations on the USGS's maps are almost certainly going to be
related.

Middle America isn't the least bit scared of California earthquakes.

And here's yesterday's earthquake:

http://earthquake.usgs.gov/eqcenter/...nc51177175.php

It's further south than last week's series,
but it's on the same fault. It's like rivets
popping on a seam between two plates. The
next one might be the one that causes the
whole thing to rip apart! And then you die.
