Newsgroup sci.geo.earthquakes 5152

Directory

Hi, just had to jump in here.
I think that the Internet has helped with some of the
communications between seismologists and the general public.  I have
noticed that seismologists do post on these news groups and are very 
willing to answer any questions you may have even from people like me 
who know very little about earthquakes.  My thanks go  to Lucy Jones
and Kate Hutton--sorry for any misspellings--for taking the time to do 
this.

The Lunation Equations - is an electronic book by Bernard Boyd. It has 
some very interesting theories and if your interest is Seismology, 
Meteorology, Astrology, Astronomy, Geology, Geophysics, Volcanology or 
Astrophysics,... 
Then you need to read this.

So what faults are being monitored as far as creep activity goes?
Where is the segment of the San Andreas that experiences the most
creep and the segment that typicaly releases its strain by brittle
fracture (I have a rough idea)...and what about these faults in SF
(Hayward etc.) are they being monitored closely with regards to creep?
I'm not aware of any fault creep in So. Cal. Does the Inglewood
Newport System show signs of creep effects?

Excellent idea that I have been pursuing from the other end.  I am a 
member of two professional societies and I work for an industry 
association as an environmental professional.  I have been trying to 
develop a system where an environmental topic or issue is nominated, and 
anyone with something to say can do so - obviously like a newsgroup so 
far - then 'someone' would compile all the messages as a position paper.
I am already that 'someone' for several local issues that would benefit 
from wider input.  Others could act as the 'someone' where they were 
directly involved, or where they would gain benefit e.g. in development 
of their academic career.
Costing is an issue, but what price is the community paying for 
duplicated effort because of the slowness of the current system in 
identifying who is working on what, particularly when some people are 
giving outdated advice.  And in the broadest sense, what price science?
But overall a good concept.

   Last message corrupted. AOL apologizes.
      Anyway, tooth pain prior to nearby quakes? Had it. been there. done
that.
More information to follow if this message gets thru.

Hi,
I don't know what geologists will have to say about I/N creepage, but if
the cracks in our slab *aren't* ground settle or seawater eating the
cement away (we're on a high water table area) then I'd say there's a
whole lot of creep going on, especially since Northridge. Had the usual
'til then -- since then we've added MANY. We're within 3 blocks of the
fault.
Geologists? Help!!! (and thanx!)

Bull droppings.
IBM was founded in the '30s a spinnoff from NCR.
IBM DID NOT EXIST IN IN 1900.
The first digital computer was ENIAC (1946).  There were analog computers,
but those were not really programable -- the were more of machines.
What you are refering to is the Holorith (*sp?) card (commonly called
IBM cards, because IBM used them heavily).

I'm glad to hear someone pay attention to the truth as much as they do
the details.

I can't speak for all journals, but I am familiar with what happens
internally with regard to Geophysical Journal International and the
forthcoming Astronomy and Geophysics.  There is absolutely no diminution
of editorial standards involved in the assessment of Fast-track papers
on these journals.  From my experiences as author and reviewer, I am
confident that the same is true of the Geological Society's 'Specials'
and of Geophysical Research Letters, at the very least. In fact, I
would be surprised if any journal were prepared to compromise editorial
standards simply to get turnaround times down.
GJI Fast-track is limited to short papers, and the system relies
heavily on use of electronic data transmission to ensure that papers
are turned around by both reviewers and editors on a very fast but not
unreasonable timetable.  The aim was to get the submission to
publication time down to three months. Since a large part of that is
associated with the printing process, it means that office handling,
reviewing and editing all has to happen in just a few weeks.  The GJI
staff seem to be succeeding in their aim -- check out the dates on the
fast-track papers.  
BTW, GJI Fast-track papers are published electronically in advance of
paper publication.  See
   http://www.blacksci.co.uk/products/journals/gji.htm 
for details and access to the papers.  And GJI can usually turn round
your full-length papers in a lot less than 18 months, too!

Not under that name.

The first ELECTRONIC digital computer, maybe.  Babbage's machine was
a digital computer and was programmable, designed almost a century
earlier.

Also because IBM is the successor to the company founded to
build the machines that Hollerith invented for the 1890 census.

I wish the would-be proponent would also read the clear and simple
instructions on how to go about constructing and submitting an RFD.
news.groups exists as for the sole purpose of discussing newsgroup
organisation, in order to avoid cluttering up groups such as this one
with irrelevant argumentation.  Despite all the verbiage, to the best
of my knowledge, no valid RFD has yet been submitted.  I am confident
that many other readers are, like myself, holding off on entering
comment awaiting its submission to the *appropriate* forum.
Let's get this stuff over to news.groups, where it belongs, and use this
group for the purpose clearly stated in its charter -- discussion of
earthquakes and related phenomena,

Way back in the late '70s, I did an analysis of global catalogues,
which I never got round to publishing.  The key result was that *at
most* 0.2% of earthquakes worldwide can be attributed to tidal
triggering.  Once you take out the known slight correlations with
aftershocks, volcanic tremors and the like, there's nothing left to
explain.

Exactly.  Very well put, Dan.

IBM Spun off of National Cash Register.  NCR is still in buisness.
Furthermore, when I say spun off, I mean, several employees left NCR and 
formed IBM.

All opinions are mine unless otherwise noted.

Almost every academic professional society has considered this issue
and many started experiments in the area.
One minor surprise is that some experiments (AIP) found it *more* expensive
to publish a web journal at the same quality as a printed journal,
probably because the screen QC tools aren't as good as for print,
and publishers have to expand their personal to use the new technology.
This may just be a transient phenomena.
Another issue is citations for tenure and promotion.
Academic societies filter out some of the worse papers through peer review.
More important they an index number- publication, volser, page- to be
used in that ever important chain-of-reference.
Furthermore someone has to archive the papers for future accessibility.
For print journals that has mainly been academic libraries.
For electronic journals that may be the academic socities and publishers
themselves with copy sites in approproiate institutions.

A creep-meter measures deformational strain where it is located,
but the deformation extends outward from the fault for a number
of miles.  There may be a *horizontal* difference in motion when
the tectonic plates are moving relentless 2-3" a year several
miles away, but semi-locked at the fault.  There may be *vertical*
difference in motion- the top of the fault may be locked, but the
middle moving, or vice-versa.  These vertical differences express
themselves as differential motions away from the fault a distance
approximately the depth of where these fault changes occur.
Therefore you have to study the pattern of movement in a *zone*
of many miles near the fault.  Prof. Segall of Stanford/USGS has
worked out the mathematics of these movement patterns and observed
many of them.
Creep strain-meters will give you point measurements of this phenomena.
Areal geodesy failitated by GPS and satellite radar measurements
will give a more complete picture.  JPL has just done some of the latter
for the entire L.A. basin and will eventually be able to answer questions
about specific areas.
Incidently, plate tectonics is not the only cause of ground motion.
Soil creep, ground swelling duing winter rain recharging of aquifers,
well-water and petroleum extraction subsidence show up in these
newer radar results and have to be sorted out.

Most of the creep is up north.  The San Andreas creeping section
is from Parkfield to San Juan Bautista. There the surface creep
rate is equal to the long-term slip rate (35 mm/yr) so it does
not appear to accumulate strain towards a big earthquake. The 
Calaveras and Hayward fault each creep at something less than
their long-term rate (I don't have a reference handy but something
like one or a few mm/yr while their long-term rate is 5-10 mm/yr)
so they still have big earthquakes. The only creeping fault I can
think of in southern California is the southernmost (Coachella
Valley) segment of the San Andreas fault where the long-term
accumulation is 30 mm/yr and the surface creep is 3 mm/yr. There
may also be some real minor level on the Imperial and Superstition
Hills faults.  The Newport-Inglewood fault is a very minor fault
with slip rates less than 1 mm/yr and no evidence of creep.
The other poster (abdikjse@aol.com) is probably seeing ground
settlement or water table problems.

Hi!
 I recently got a project in geography: To record all information about 
earthquakes from today ītil January 15th. Scared the ... out of me until 
I thought about the net :)!
	Can anyone help me with information on how I should proceed to get the 
most out of the I-net? Addresses and tips about how finding the 
information I need in this and other gropups are welcome. Please mail 
me.
Yours sincerely
