As well as the sideways movement between the plates, the sea floor is estimated to have risen by several metres, displacing an estimated 30 km3 (7 cu mi) of water and triggering devastating tsunami waves. The waves did not originate from a point source, as was inaccurately depicted in some illustrations of their paths of travel, but rather radiated outwards along the entire 1,600 km (994 mi) length of the rupture (acting as a line source). This greatly increased the geographical area over which the waves were observed, reaching as far as Mexico, Chile, and the Arctic. The raising of the sea floor significantly reduced the capacity of the Indian Ocean, producing a permanent rise in the global sea level by an estimated 0.1 mm (0.01 cm or 0.0001 m)
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.

No wonder they won't show what's going off down there! Thad Allen says that everything's HUNKY dory and the Static Kills almost ready to be put into place. Yeah right. Don't wanna go off topic but wasn't there a quake in Louisiana yesterday?? I was also reading on beforeitsnews today that a nuclear charge was used somewhere around the area..
That bit of sea floor definitely looks unstable
