over or nearby that quake...

-
- If I had a hammer, I would hit over the collective heads
of all the geologists who are connected to Big Oil and won't speak to the
issues involved in "petrochemical" drilling/subsidence, et al
and how it relates to many quakes in these areas according to USGS itself!
-
- The new faultlines that Jack Reed suspects are related
to the New Madrid are in yellow in the above graph.
-
- You saw my post from May 10th about Jack Reed's theory
about the missing faultlines connected to the New Madrid so once again,
I'm going to post a little tidbit of it in hopes that someone out there
pays attention.

- Jack Reed's faultline outlined in yellow once again for
comparison and it's very close to his missing faultline:

- Cut to the chase from my May 10th post:
-
- Reed, a retired Texaco geologist-geophysicist who has
been studying the region's geology for over 40 years, says the accepted
theory of a quiet geologic evolution of the Gulf of Mexico Basin is fundamentally
flawed and needs to be revised.
-
- According to him, the Gulf was and is tectonically active
-- and it is the likely origin for not only the New Madrid seismic activity,
but also for the Middleton Place-Summerville seismic zone near Charleston,
S.C.
-
- "For all the years I have worked the Gulf of Mexico
Basin I have been forced to accept the 'passive' Gulf formation theory,
which holds that the only movement in the basin is updip sedimentary loading
that moved the salt southward," Reed said. "But there is little
evidence to support this theory, and it doesn't fit what is observed geologically
or geophysically.
-
- "As Hugh Wilson said (1993), 'It would be geologically
unusual for such a large basin as the Gulf of Mexico to remain almost tectonically
undisturbed for 170 million years while major orogenic disturbances repeatedly
struck bordering areas.'"
-
- Reed, over the years, has gathered evidence that supports
plate motion in the Gulf basin. Thick salt and sedimentary sequences in
the basin mask this tectonic motion, but there is enough basin and peripheral
evidence to show plate readjustment is occurring -- evidence, he says,
in the form of volcanics, earthquakes and rift zones that are accompanied
by magnetic, refraction, seismic and gravity data.
-
- Questions? Answers!
- One piece of this evidence, according to Reed, is the
apparent connection of the New Madrid seismic zone with the Gulf rift features
to the south.
-
- "This northeast trending earthquake zone appears
to connect with the northeast trending Monroe Uplift, the LaSalle Arch
and, possibly, to an active seismic zone located in and around Sabine Lake
on the Texas-Louisiana border," he said.
-
- This complex of doming and seismic centers is similar
to another Cretaceous age triple juncture located in the northeastern Gulf
of Mexico Basin. Doming of the DeSoto Canyon High during the Jurassic to
Cretaceous created this triple juncture, which includes the Cretaceous
Shelf Edge, the Suwannee Strait and the West Florida Escarpment.
-
- If the New Madrid seismic zone is indeed part of a triple
juncture, he continued, there should be an expression of this limb trending
along a line in a northeast direction.
-
- So Reed conducted a study using data from the U.S. Geological
Survey's National Earthquake Information Center and the USGS map "Earthquakes
in the Conterminous United States." He only studied earthquakes measuring
at least magnitude 5, and found that while most of the earthquake centers
are random with no alignment, there is a well-defined earthquake trend
extending northeastward from the New Madrid seismic zone across the United
States to Canada, where it joins with the St. Lawrence River seismic zone.
-
- Within the boundaries of this earthquake alignment there
are:
-
- Sixty-one seismic points that have a magnitude of 5 and
greater.
- Several large earthquakes dating to the early 1800s,
all measuring over magnitude 8, all occurring within a couple of months
of each other, all centered in a northeast trending line.
- The two 5+ earthquakes that occurred earlier this year
in northern New York state and southern Indiana.
- "There is definitely some form of movement occurring
along this trend," Reed said, "and it appears to be active today."
-
- As he continued that trend south of New Madrid he found
that it was in line with the Monroe Uplift.
-
- "Suddenly I could see that this area had doming
much like I had seen at the Desoto Canyon in the Gulf," he said. "This
entire zone through the United States is suffering some type of tectonic
activity that I believe is tied to the deeply buried tectonics in the Gulf
of Mexico."
