A bibliography compiled during  the AGU Chapman conference on Tectonics and Topography, held Aug 31 to Sept 4, 1992, is available via anonymous FTP.  This bibliography of over 1200 references contains mainly reference from the geomorphologists attending the conference (Bill Bull's entire Tectonics library), but also contains many references from large scale geophysical modelers.  It is available at:
magic.ucsb.edu     [128.111.254.108]
directory:  /pub/chapman
One file with endnote stylesheets can also found in the directory: /pub/endnote       
The files are in three formats, endnote for macintosh, text for procite import, and text in gsa bulletin format.
I would like to thank Dorothy Merrits and Mike Ellis for bringing together a diverse group of people, and making the conference work.  And Dave Robbins for getting the anonymous FTP server up and running.

Considering that there is a tsunami warning system for the Pacific, what was
that system doing right after that quake off Nicaragua?  I was under the
impression that earthquakes were monitored and that people in coastal areas
were warned about approaching tsunamis -- at least since that disaster in Hilo,
Hawaii.

It's not a question of interest to Central Americans.  There are faults off
Vancouver Island.  So people on Vancouver Island or western Washington might be
interested in how well tsumai warning systems work.

	Well, I went by there in 1984 (?) after we had had a lot of
rain. The signs all said "Old Faithful" went off regularly once
an hour. As we drove in the gate the geyser was just going down.
Oh, damn! We thought... we have to wait an entire hour to see it!

	No, they told us: the period was very strongly influenced by
the amount of rain. Because of all the rain the period was much shorter
than usual, only about 10 minutes. Sure enough, we stayed through several
cycles, and it was something like 9 minutes 14 seconds on the dot, as
I recall. Consistent enough that I could literally set up the camera,
start the timer, run around to the other side, and get a picture of me
with the geyser just starting up.

	So how do they disentangle the effects of rain from the earthquake
prediction part? Oh I know... they haven't HAD any rain there the last
few years :-)

	What about the earthquake-predicting well we used to hear
about in ca.earthquakes all the time?

As a mechanical engineer, a potentially rewarding route would
be to work on geophysical instrumentation, a field sparsely
populated but of much necessity for advancement. Unfortunately,
instrumentalists tend to be spat on by the upper brass as attested
by the strongly biased geophysical literature which nearly always
shows nice "positive" theories and nearly never reports on
experimenting with instrumentation. Often, these theories are not
only half-baked but also rely on data accepted without questioning
as godspell truth, the most expensive instrument giving the
"truest" answer, which illustrates how gullible many a
geophysicist can be.

Money for instrumentation is likely to come from the industry and so
constitutes "real money". This tends to get things done in time, with
tangible results at the end. Geophysics is a vast field with studies
ranging from laboratory-scale phenomena in rock samples to several
Earth-radius scale events in the magnetosphere. The future appears
to be in environmental matters; therefore, the sub-disciplines of
oceanography, meteorology and aeronomy are good wagons to catch.
For oceanography [including marine geophysics], the best place is
probably UCSD, although they may be biased towards the electronic
side of instrumentation.

The only place I know where "Instrumentation" is institutionalised
within academia is in Australia. You may find enlightening the plea
of Prof. Sydenham in favor of measuring science by reading his
short note entitled "Limits to the advance of the discipline of
measurement science", published in J. Phys. (E): Sci. Instrum.,
Vol. 17, 1984, p716-717. Sydenham happens to be a geophysicist.

So, enjoy, apply for a Fulbright scholarship, visit the world and
endeavor into the pleasure of doing something useful for Science,
particularly geophysics as it is in dire needs of it ...

It depends upon several factors. Gary Carver tells me that they have found evidence for tsunami deposits several km's up the fjords in Alaska.  It is a factor of how high the wave is, and how the groundsurface funnels the wave. It can be a thirty or so meters under the right conditions, but five to ten is probably more like the rise to be expected.  Oceanographers can models these waves and come up with predictions.  I belive Bernard has a book out on tsunamis.

If the ground shakes while you on the coast, it's best to head for higher ground. The only problem with this is that the cliffs will probably be coming down due the earthquake. We disscussed and laughed about this dilema while working on the Petrolia earthquakes. Luckily, no large earthquakes occured while we were out on the coast.

There is an article in the NYTimes some time last week on this.

It may or may not be the same geyser (I don't recall whereabouts Calistoga
is!), but Paul Silver and his wife 'discovered' such a geyser a couple of
years back.  It's a local 'attraction' called 'Old Faithful' and is located
in/near the north part of the Napa Valley.  They were visiting it as tourists
and the guide announced that the geyser, normally as regular as clockwork,
showed anomalous behaviour prior to large earthquakes in the Bay area.
Paul - the sceptic as ever - said (more or less) "Prove it!" and was taken
to their records, where every eruption of the geyser was logged in detail
for umpteen years past.  A quick inspection supported the guide's claim,
so Paul arranged for copies of all the records to be sent back to his
institution (Carnegie-DTM in Washington DC) where he analysed them in
meticulous detail, and found that the claim was upheld.  He has given a
couple of AGU talks on that work, but I don't recall seeing it in print
as yet.

The galling part for me (and no doubt for a few others) is that I drove 
past the place a few months before Paul and Natalie did, and didn't give
it a second glance!

First, lets try to find the actual Science article.  The NYT is good but

This is different than correcting for the affects of rainfall such that
one can tell whether a specific change is related to an earthquake or
to another cause.  The pattern they see may not correlate with rainfall
but specific changes that look like earthquakes may.  In the late
summer of 1991 there was a change there that Olga Kolbek (the woman who
runs the monitors there) said was an earthquake precursor but Paul
Silver in a seminar at the USGS said looked like one but that there
were lots of other things that looked like that too so it couldn't be
relied on.

Damn the mail is slow.  I will post some pertinent quotes once I find
a copy.

The tsunami traversed the approximately 35 miles to the coast in minutes.

It won't work at all for near-shore quakes.  People who live in places like
Port Alberni on Vancouver Island are probably screwed.  Wouldn't want
to live in Squamish, BC either with the way Howe Sound funnels up to a

I am taking a cylcostratigraphy seminar course this semester and we
have been looking at papers by A.G. Fischer.  He has published quite
a number of papers on cylcicity relating to orbital variations.  I
have some of the papers with me and I will list them.

	Fischer, A.G. 1981. Climate Oscillations in the Biosphere.
		In: Biotic Crises in Ecological and Evolutionary Time,
		M.H. Nitecki. Academic Press. p. 103-131.
  	Fischer, A.G. 1986. Climatic Rythms Recorded in Strata. Annual
		Review of Earth and Planetary Science. v. 14 p. 351-376.
	Gilbert, G.K. 1895. Sedimentary Measurement of Geology Time.
		Jour. Geol. 3:121-127.


The first paper deals more with 300 MY "super cycles" but does talk about
the shorter Milankovich cylces.  Gilbert was one of the first to see these
cycles but could not prove it (no radiometric dating).  These papers
are not as straight forward as you may be looking for but they deal
with the subject in a Sed/Strat context.  I can look up other, more
straight forward, articles if these don't work.

Speaking of cycles, does anyone else have input about these Milankovich
cycles found in the stratigraphic record?
