Posted on 10/17/2004 9:46:13 PM PDT by SunkenCiv
An impact event occurred at 2.15±0.5 Ma in the Bellingshausen Sea. It littered the oceanic floor with asteroidal debris. This debris is found within the Eltanin Impact Layer. Although the impact layer was known, the crater had yet to be discovered. We have found a possible source crater at 53.7S,90.1W under 5000 meters of water. The crater is 132±5km in diameter, much larger than the previously proposed size of 24 to 80 km.

Difficult to get my mind around this considering what a bullet does in water. The energy that derives from something this size traveling at these volocities is mind boggling. Punching through 3+ miles of water and still leaving a giant crater.....geeez!
In researching this, I discovered that there are a great many people who are willing to accept any explanation, as long as it is more bizarre than the last. Ley lines, the "harmonic recipricol of the speed of light," whatnot...
Thanks. Looks like it would make a good bottle cleaner.
I guess you don't believe in magnetogravitic clamping of tripoles to gaussian lines of force, to effect the climbing out of the tropics, along lines of longitude, by Antlantean mariners, either. They used the method to build speed poleward, then cut power, and let the earth's rotational spin move them westward, (due to their inertialess state)in a ballistical arc, as they slowed and eventually drifted equatorward again.
Natually, they only needed to reverse polarity to move Antipodal, to get around Asia or South America. Yes, it was inconvenient to only be able to use this method for west-to-east travel, but one-way travel also simplified traffic flow, and conventional means could be used for local navigation.
I understand they were only decades away from perfecting a cross-clamping at right angles that would have taken them right out of the atmosphere if they wished, when the island sank. Some of the Masters believe the destruction was related to this research.
Churchward mistranslated and misunderstood The Writings: Mu and the "roads" (later found to correspond to the 'ley lines') was really an allegory for the research into the muon-strings to clamp onto for the spread of Mankind to the stars.
Perhaps it Is Best if such is left Forgotten, as there really are Things Man Was Not Meant To Know.
Cthulhu is waiting, now that the Mad Arabs are awake and restless, and will protect The Secret Knowledge.
As proof, if you slow down the recording of an Imam's mosque call to prayer, and play it backwards, and filter it properly, you can here "Suk hototh...." in the background. The Seven Seals are about to be broken.
Okay. Well, that explains a lot...
Two Catastrophe ScenariosAbout 2.2 million years ago, a chunk of space debris about a kilometer in diameter splashed down in the Bellingshausen Sea between Antarctica and South America. It was some splash! The splash zone was about 20 kilometers across, waves 4 kilometers high raced away from Ground Zero, and a column of salt water ascended miles high into the upper atmosphere. The TNT equivalent is estimated at 12 billion tons. Ice clouds formed and shaded the planet, causing severe climate changes. On the floor of the Bellingshausen Sea, 5 kilometers deep, lies the Eltanin Impact Structure.
by William CorlissOcean splashdownAn asteroid between one and four km in diameter that splashed into the Southern Ocean, 1500 km SW of Chile, just over two million years ago, may have worsened a period of global cooling that saw the emergence of modern humans... The impact in question was first discovered during a cruise of the Eltanin in the 1960s: betrayed by anomalously high amounts of iridium in ocean-bed cores... Gersonde and his colleagues have taken another look, their results coming from a cruise in 1995 by the research ship Polarstern. The impact left a distinctive 'signature' of geological layers, very like that of the Chicxulub impact. Lowest in the 'impact' sequence is a thick layer of disordered rubble, full of chunks of rock up to 50 cm across: this layer represents the large-scale disturbance immediately after the impact as the ten-megaton blast ripped up the ocean floor. This layer took around four hours to settle after the blast. Smaller particles, such as grains of sand, took longer to settle, explaining why this layer was found immediately above the rubble layer. Capping the whole sequence is a thin layer of very fine sediment, dispersed over a wide area. This would have contained fine-grained material (including vaporized asteroid) flung high into the air and which took days or months to settle out. This layer contained the iridium.

I've seen energy calculations done in about 1968 that claimed such an event would create an enormous amount of heat-energy to "pastuerize most of the planet". Part of the hypothesis concernered studies of Verdevoort Ring in S. Africa & other large scale ancient impact sites, and concluded an object of this size would be sufficient, in a water strike, to crack the mantle, and release enormous amounts of magma, which would create a relatively long term additional vaporization. In turn, the vaporization would slow heat disipation and radiation to space. In effect, there would be an essentially dry area of ocean floor, with a wall of seawater surrounding it, and a rising column of superheated steam for a fair amount of time, until the seawater managed to cool the crater enough to reinundate it.
The results indicated a significant rise in atmospheric temperature, torrential rains & winds, followed later by 'atomic winter' type cooling. It was a scenario of a major global killing event regardless of impact point, assuming a strike in 1-3 Km depth ocean.
In addition, naturally, they mentioned the super-tsunamis this would also create.
A lot more fun than accepting a sponge, even a 'carniverous' sponge, when something complex, whacky, ignorant, and baseless will do.
The Eltanin impact did happen. And it had nothing to do with Atlantis, Mu, or the Sphinx. If you prefer not to receive GGG pings, let me know.
Opps, don't misunderstand; there are two subjects there,
the crap that some would rather believe about the "Eltanin antenna" and the actual Eltanin Impact. There is no intent to imply the impact is in the same calss as the "antenna".
One has nothing to do with the other; one is pseudoscientific crap; the other an event. It is unfortunate that they are linked.
The calculations I mention were honest & real calcs, in a real study, by an atmospheric physicist, an oceanographer, and another physicist. They were apropos to the event portion of the post; and the prior observation, by someone else, that it would be a 'major kill event'. They help to scale and explain the mechanism of such a 'kill', and bring in factors not usually mentioned in relation to a large impact.
As to GGG pings, I read a lot of the archaelogical matterial you alert to, though often don't comment, especially the Euro-Americas related information. Ditto for the "Graves" portion of GGG. Often, I don't have time to more than read the articles, skipping the following posts altogether.
It was you, after all, that said you didn't recall Churchward writing much about Atlantis. I was just explaining the reason I even mentioned him, in the context of what some would choose to believe in, (the subject of the other post responded to) rather than mundane real explanation of the "mysterious photo". I know I'm not the only one guilty of a bit of late night silliness on some of these threads, and if it confuses or offends you, I'm sorry. I'll try to refrain, though that is rather temperamentally difficult for me.
Most probably, I should not respond to more than one post at a time, in a compound econo-reply.
In short, keep the GGG pings coming.
Thanks, I just didn't know if you were displeased with the initial post. Originally, I mentioned the Eltanin Antenna because it was discovered, hmm, I guess during the same (1960?) seafloor study in which the research ship the Eltanin discovered the impact evidence. :')
We need to remember that, when that "antenna" was first photographed, no one knew what it was. Not sure when the offbeat explanations began, although I think it was discussed in that page Junior linked to. I don't consider it pseudoscience, because I doubt that anyone ever purported it to be a scientific explanation.
Impact tsunamiEltaninAbstract: Employing classical tsunami theory and elementary assumptions about the initial shape of impact cavities, we compute tsunami from the Eltanin asteroid collision at 2.15 Ma. An Eltanin impactor 4 km in diameter would have blown an initial cavity as deep as the ocean and 60 km wide into the South Pacific and delivered a 200300 m high tsunami to the Antarctic Peninsula and the southern tip of South America 12001500 km away. New Zealand, 6000 km distant, would have met 60 m waves. Generalizing these results to other size impactors, we fit simplified tsunami attenuation laws to maximum tsunami heights extracted from the full-wave calculations. If Eltanin was 1 km in diameter instead of 4 km, its waves would have been at least five times smaller. An asteroid the size of Chicxulub (10 km diameter), had it fallen into water deeper than 1000 m, would have sent a 100 m tsunami out to 4000 km distance, even if shoaling amplifications are neglected.

Sorry, neglected to mention (as I'd intended to do) that the link in the previous message came from Scirus.org, a scientific search engine.
Before anyone goes off on me, the third one here isn't directly related -- just pertinent because A) impact is involved, albeit a different one, and B) Antarctica is involved.Iridium-rich layers and catastrophismKyte et al have discovered a 2.3-million year-old sedimentary layer under the Antarctic Ocean that contains iridium and gold concentrations comparable to those in the Cretaceous-Tertiary boundary. The noble metals are mostly contained in millimeter-sized grains that resemble ablation debris from a large extraterrestrial object. Unlike the Cretaceous-Tertiary episode, however, the newly found layer is not accompanied by evidence of mass biological extinctions.

No. 18: Nov-Dec 1981When Antarctica Was GreenPeter Webb and his coworkers have found pollen and the remains of roots and stems of plants in an area stretching some 1300 kilometers along the Transantarctic Mountains. The Antarctic wood is so recent that it floats and burns with ease. Webb's group postulates that a shrub-like forest grew in Antarctica as recently as 3 million years ago... Nevertheless, these deposits of fresh-looking wood do suggest that trees recently grew only 400 miles from the South Pole. Also of interest is the fact that the sedimentary layers containing the wood have been displaced as much as 3000 meters by faults, indicating recent large-scale geological changes.

No. 45: May-Jun 1986An Antarctic Bone BedW. Zinsmeister was accustomed to scoff at the idea that the Age of Dinosaurs ended violently with the impact of a giant asteroid some 65 million years ago. He always asked: "Where's the layer of burnt and twisted dinosaur bones?" His certainty was shaken, however, when he began mapping fossil deposits on Seymour Island, Antarctica. He didn't find the dinosaur bones but rather a giant bed of fish bones at least 50 square kilometers in area. Some sort of catastrophe must have annihilated untold millions of fish. And guess what? This great bone bed was deposited directly on top of that layer of extraterrestrial iridium that marks the 65-million-year-old Cretaceous Tertiary boundary at many sites around the world.

I should have looked for additional work on the dating of this tsunami, but anyway...A possible Plio-Pleistocene tsunami deposit,Many features of the Hornitos conglomerate bed are considered to be characteristic of a tsunami deposit according to the criteria identified by Einsele (1998)... An alternative interpretation as a large debris flow deposit derived from the adjacent alluvial fans is unlikely, as: 1- it is difficult to envisage how a debris flow could result in subaqueous scouring of the shoreface and incorporate shell material, sandstone intraclasts and foreshore-derived pebbles into the resulting deposit; 2- any debris flow deposit is likely to be eroded and reworked by subsequent storm and fairweather processes, and 3- the location of the conglomerate deposit ranges from 3-5 km from the coastal scarp and its associated drainage system... The Plio-Pleistocene drainage is still preserved along the coastal cordillera... and is of insufficient size to develop such a high magnitude event...
Hornitos, northern Chile

A possible explanation for both the depositional environment and thickness of the Hornitos conglomerate bed is that the Pliocene tsunami was an extremely large magnitude event... supported by the size of the clasts incorporated within the flow that were transported from the alluvial fan into the shoreface... a particularly powerful current would have been required to remove unconsolidated sand, scour at least a metre down into the shoreface and rip-up large clasts of semi-lithified sandstone. This powerful event left a substantial deposit in the upper shoreface... only limited reworking took place prior to deposition of the next bed. As the top of the conglomerate appears to be abruptly overlain by shoreface sandstones, it is likely that some reworking has taken place...
The large scale of the Hornitos conglomerate bed, as previously noted, suggests that it represents a very large magnitude event deposit. As such this event bed should form a useful stratigraphic marker correlatable throughout the Pliocene succession of northern Chile.
