Discussion on newsgroups about some "thing" perhaps is a good thing,
but not over two hundred single predictions.  For that I'd be accused
of taking over someone's web site.... LOL

I realize you access usenet through Google, otherwise I would
strongly recommend the group alt.earthquake.predictions. It was
my intent for that group to be for exactly that - posting and
discussion of predictions.

It's too bad Google doesn't seem to have the manpower to take
a few moments to add it to their system despite repeated requests.

Anyway, I'm now relocated near Berkeley in Albany and I'm delighted to
be in the East Bay so I can get our little instrument installation
underway as well as other projects.  I'm sorry you aren't here to
enjoy the launch of this project.  This is something I've wanted to do
for four years and at long last, it's a happening thing.

Moved again?

It's good you have projects. I have them too, but they aren't all on
seismology. And having a 50+ hour a week job tends to put a cramp in
one's free time. Actually, I've been doing some 60 hour weeks lately.
Makes for good paychecks, but.... I can't see how some folks do 80.

I see Lac Kivu took a leap, so where do you suppose the next really
unusual earthquake event is going to take place?  It's not the size
that counts, just the where....

That is not a common place to see quakes, but not unheard of, being
smack in the middle of the East African Rift Zone. The downside is
the lack of strong earthquake building codes, not that that area is
capable of enforcing and/or affording them easily.

Hi Brian,

I can understand your many hours of work. When I raised my daughter
after my divorce I was working three jobs and seven days a week and
still had the research group and it was during that time when I went
to Sacramento to tend to the water heater legislation, thus my life
was rather wall to wall and for the most part it is now as well.

The monitoring project has been on the back burner for years and I'm
delighted to finally start getting the instruments in place so we can
see what an array of them will produce.

But as for newsgroup predictions, it ain't gonna happen. Been there,
done that, found it a really negative experience. LOL

Take care and don't work to hard,

Petra

Is the lack of seeing quakes due to lack of instrumentation
there?

Not really.

First of all, even in the absence of instrumentation, the local
population would feel sizeable earthquakes. Of course, if there was a
lack of (global) news coverage there, we might not see reports.

Second, lack of local instrumentation would only really affect the
detection of fairly small earthquakes. For larger 'quakes, the global
instrumentation would be sufficient for detection. I'm not sure what
the lower bound on globally detectable earthquakes is, but IIRC it is
fairly small. The monitoring for detection of nuclear testing has
resulted in a seismic monitoring system that can pick up earthquakes
anywhere on earth, as long as they are big enough.

Well, I'll be blunt....

Unless a person wanting to analyze your predictions were to
constantly monitor your website, making backups of it and
verifying for, shall we say, no edits, then it raises the
spectre of postdiction.

I'm not saying you do that, but because it has happened,
because posts on websites have been edited after the fact,
there has to be some effort to make sure that it isn't
happening in your case.

Although posts on usenet can be forged, it is much more
difficult to pull off a post-facto edit.

When you come to a group and say, "I predicted that quake,
it's on my website", it's very difficult to prove that you
might not have put the prediction up after the event occured.

Again, not saying you do that. In fact, I think you have the
integrity not to do so. It's just that the possibility of it
happening can lead to accusations. I just didn't think you'd
want to have to deal with that and/or would like to promote
a more independantly verifiable way of posting predictions.

Brian,

Thanks for your thoughts on that, but I guess I should tell you that
my predictions have been monitored by several scientists since the
onset and thus there never would have been a problem to prove they
were authentic and without changes. I also printed hard copies of
them as this issue came up for discussion some years ago.

But my primary thoughts are very simple. I don't need the discussion,
but rather to just stay focused on the work and my research and that's
enough for me. And at present, it's the research and writing and the
predictions and web page will happen later this year and much of what
I'm doing now can be written about for the new web page when I build
it. The instrument data reports I think will be an interesting
addition. While most web pages have a lot of talk, no one who's an
amateur that I'm aware of has their own instrumention readings to
share. I think it will be a new fun endeavor for share with the
readers.

And you know, when the new page goes up if you want to take the
position of site monitor to confirm those predictions don't change,
you're more than welcome to hop over and join the scientists.

The point now is to just do some good solid research and get the
network set up. I haven't lived on the Hayward Fault for a very long
time and it's good to be here and also have close access at UCB when I
need technical assistance. Berkeley is a very cool place. I love
it. I was in a Bolivian grocery store the other day "La Tierra" down
on 10th Street (I think) near University and I found refried black
beans. I asked them if La Tierra meant My Earth and one person said,
"No, my dirt." And the other said "My Place." I think it means My
Earth, but to each his own in interpretation, right?

When I was here the last time I was working for Cutter Laboratories
and that was a really cool job.

I've asked Alan and John already but are you of the opinion that no

Well Roger,

I don't know how many scientists read this newgroup, but from what
I've seen most are not willing to declare they are scientists... so I
don't know.  But if you are going to gather a learned consensus
perhaps asking scientists who are pro-earthquake prediction might be
a good idea.   It seems to me that John is quite anti-prediction thus
not a good person to ask.  I don't know Jones well enough to form an
opinion.  Why not ask Musson or Wyss as an example.  I'm sure you
could find their e-mail addy's.

You've just hit the nail on the head if you're looking to understand
why people who actually know science don't take you very seriously.

You are EXACTLY WRONG in saying that you should perhaps "ask scientists
who are pro-earthquake prediction." In order to gather a learned
consensus, you must face the most adversarial of your critics. You must
SEEK OUT the most SKEPTICAL observers. That is the core of science, and
you clearly just don't get it. When scientists are skeptical of your
work, they're not being personally hostile, they're just being true to
the principles of science.

Even beyond the null hypothesis, that we don't yet know how to reliably
predict earthquakes and may or may not ever be able to, there is reason
to speculate that it might be PROVABLY IMPOSSIBLE ever to predict
earthquakes, no matter what technology you ever develop, because of the
elements of mathematical chaos in the system. Take a thin rectangular
slab of spring steel. Hold it vertical, holding from the very bottom
edge. Will the top bow to the left or to the right? It is fundamentally
impossible to predict, no matter how precisely you specify the initial
conditions, because it is an intrinsically highly chaotic system. It's
not that wild an idea to think that earthquakes might be similarly
chaotic, only in far more dimensions.

Hi Link,

Thanks for you input. In discussing forecast modeling we should
realize the people discussing this should be those who understand it's
potential in that it is an excellent vehicle to inform the public of
earthquake safety issues while not predicting major earthquake events,
whereas prediction itself would cover that better.

Thanks for you input. In discussing Purple Unicorns in the Garden
we should realize the people discussing this should be those who
understand it's potential in that it is an excellent vehicle to
inform the public of the benefits of Purple Unicorns.

Thanks for you input. In discussing Astrology we should
realize the people discussing this should be those who understand
it's potential in that it is an excellent vehicle to inform the
public of Astrology.

Thanks for you input. In discussing lint in the navel we should
realize the people discussing this should be those who understand
it's potential in that it is an excellent vehicle to inform the
public of Observing navel lint.


See how silly you are petra?
