Does anybody have any information on crypto-explosion sites in the
midwest (Kentland,IN.-Serpent Mound, OH.-Jeptha Knob,KY.-Glasford,IL.-
Wells Creek,TN.-ect.?)  Has there been any coordinated research on 
these sites?  In a class I had here in Indpls. Dr. Robert Hall said
that the two theories for these anomolies were; 1) Some sort of
explosive volcanic outgassing w/out magma. 2) ET strike (most likely
comet.)  Has anybody heard any other theories?  Are there any dates
for _any_ of these sites?  I was wondering if there are any 
contemporaneous sites?  If you just look at a map of the sites you can
almost imagine a comet that had calved giving the midwest a shotgun
blast of dirty ice.

Thanks,

I have to do an essay in which I have to discuss the arguements
for and against plate tectonics theory. Mainly dealing with the
arguement not the mechanics of it.
I have been looking into "THE EXPANDING EARTH" hypothesis by Carey et. al.
I would like to hear from anybody concerning both sides of the arguement 
along with references please.
Lastly I heard that there less subduction zones than areas where new ocean 
crust is being formed. (from The Expanding Earth)

The refs people have given on this problem are on plate movements. The
original questioner asked about earth expansion, a different but related
problem. The most cogent paper I know on that is M W McElhinny, Bull.
Aust. Soc. Explor. Geophys. 9, 149-152, 1978, "Limits to Earth Expansion".
(Although the journal is thought to be rather obscure in most of the world 
it should be easy to find in or near newcastle.edu.au !) If 1978 is thought 
to be too old, use Sci Citation index on this paper and its references to 
get up to date. But I'm not going to do all a student's homework.

	What the heck, let's get out the book:

3:48PM, March 20, 1980:
	The first earthquake that indicated to geologists that something
	was up. Two months from this until the whole thing blows.

noon, March 27: erupts ash into the air the first time.

Noon, Saturday, May 17:
	Angry Spirit lake property owners denied access to their property
	stage a demonstration in Toutle. Law enforcement officials agree
	to escort them onto their property, but only for a few hours.
	Authorities agree to run another caravan in at 10AM on May 18.

8:32AM, Sunday, May 18:
	A crystal clear sunny weekend morning, making for good photos.

	The north side of the peak collapses and "uncorks" the pressure.
	Amazing set of slide photos taken by a Geophysics student camped
	10 miles NorthEast of the mountain. Eight minutes later he's driving
	like mad trying to get away. The set of photos you always see run
	like a movie were taken by an amatuer photographer 15 miles north
	of the mountain.

	Photos are also taken from an airplane flying over (trying to get
	away!) and by climbers on Mt. Adams. The airplane has an open mike
	being recorded at an airport; the sounds of the camera clicks allow
	their photos to be timed with great accuracy.

	Superheated mudflows pour through Weyerhaeuser Co. logging camps
	12 miles from the mountain, destroying everything. Three people
	die. Many loggers would have died except it was Sunday... so nobody
	at work. One lucky pair of tourists drive to the camp to take photos,
	arriving at 4:30AM, and leave again at 8AM, just in time to survive.

1 - The fossil record - There is a species which can only be found in strata
    of the tip of South America, South Africa and Antartica.  These are
    separated by deep oceans, but could not have been for that species to
    appear in all three locations so they must have been together at one time.
    (Triassic Lystrosaurus).

    (Correlating ice flow directions of an ancient iceage for the three land
     masses substaniates this arguement - Paleoclimatic evidence).

  - Scotland and Newfoundland have a common species of trilobyte which is
    different from another species found in England and North American.
    This suggests that the Atlantic did not exist and another ocean (the
    Iapetus) did between Scotland/Newfoundland and England/North America.

    (This is substaniated by noting the mountain range (orogeny folds) generated
     by the closure of the Iapetus existing between Scotland/England
     (Caledonian) and Newfoundland/North America (Tachonic)). (See also the
     Variscan / Hercynian).

2 - The magnetic record - By examining lava deposits it is possible to determine
    the location of the magnetic North pole through time.  By comparing the
    record from two diverse sites it is possible to see similarities
    (the continents moving together relative to the movement of the pole) and
    differences (the continents moving relative to each other).

  - Either side of spreading ridges, magnetic pole reversals can be seen to
    mirror themselves.

    (This is substaniated by examining the ocean floor deposits, only recent
     deposits are found near the ridge.  Further away the are underlayed by
     older deposits (over lap ??)).

3 - The physical evidence - Transform faults of spreading ridges are curved
    and concentric, and there is an obvious 'fit' of the continents.

whether they are completely aseismic. An example was quoted of the

more.

The best sources of data are probably field trip guide books published by the local geologic societies.  I think you can find a list of societies in either the October or November issue of Geotimes.

Another good source are the guidebooks published for the sectional and national meetings of the Geologica Society of America or the American Association of Petroleum Geologists.

The Geologic Society of America published 2 or 3 years ago 6 regional guidebooks to geologically interesting places.  The books are part of the DNAG (Decade of North American Geology) series.

I am aware of such measurements being made by SLR (Satelite Laser Ranging),
VLBI (Very Long Baseline Interferometry), which we do, and assume that it
has also been done using GPS.  I am not aware of it having been done by 
'radar astronomy', do you mean VLBI?

In any event, all three techiques require that measuremnts be made over a
period of a few years at least as it is necessary that the observed motion(s)
be large with respect to the uncertainty in position(s) for the sites at which
the measurements are made.  I.e. with uncertainties of position on the order 
of a cm or so, one has to wait 2 years or so for 5-10 cm of movement to 
accumulate in order to infer velocities with an uncertainty of a cm/yr or
so.

Surely there is no technique that allows a 'direct' measure of such small
motions.  I.e. all such methods infer the velocity from changes in position.

    Isn't this what the Science Citation Index was designed for? Look
up the paper you already have in the Citation Index to find out which
newer papers have used *it* as a reference! Of course, you may only find
papers that say "Smith and Jones (1722) are full of &%$#", but them's the
breaks. You can continue the citation search finding newer and newer
papers that refer to the ones you find, until you reach the most recent

According to the opinion of a writer in Geotimes sometime in the last 6 months,
there are some serious factual errors in several of the books, in particular,
the author Halca Cronic (sp?) was singled out for inaccuracies. 

I have no personal knowledge of the areas under dispute and can only relay the
concerns of the person who wrote into Geotimes (whose name I recognized, but
cannot now remember).

I have several of the books, and for areas I do not already know have found them
to be interesting summaries, but I cannot vouch for the validity of the information.

There was a paper written by Marshall, P,D., and Basham, P.W.,
Discrimintion between earthquakes and underground explosions employing
an improved Ms scale, Geophys. J. R. astr Soc, (1972), 28, 431-458.

I'm afraid it is now a bit on the old side but in it they attempt to
provide some sort of path correction in the determination of Ms. This
path correction should give an idea of the Rayleigh wave dispersion.
They find corrections for Eurasion and North American earthquakes and
explosions in an attempt to aid discrimination between explosions and
earthquakes. I would suggest P.D. Marshall as a good name to start a
literature search with! If you require his address just e-mail me.
