Has the Earth’s Surface Been Shaped by Immense Tornadoes?

In 1974 Ralph Juergens speculated as to what landforms an electrical discharge would leave on the Lunar and Martian surfaces. (1) Juergens suggested that an interaction between the Moon and Mars could have produced some of the surface features found on both worlds.
On the Moon it was suggested that craters and sinuous rilles could form by an electric discharge. On Mars the Mariner 9 spacecraft had only two years previous (1972) revealed some remarkable Martian surface features; Juergens suggested that Nix Olympica (now Olympus Mons) and the Canyon-lands (now Valles Marineris) were just some of the features formed by an electric discharge on that world.

If such a wide variety of surface features could form on both the Moon and Mars by the same process, what, if any, landforms could a similar planetary scale discharge produce on Earth?

Water World

One look at the Earth from space and an immediate and obvious difference between not only the Moon and Mars but all the other terrestrial bodies is apparent, most of the Earth’s surface is covered by a veneer of water. Not only water but all manner of ‘volatiles’ constantly emanate from below the surface be it on land or under the sea.

On a planet with an abundance of volatiles would an electric discharge of the scale envisaged by Juergens, one appearing as a giant electric arc, leave dry valleys and craters, or would such a discharge take on a completely different appearance? If a discharge can produce surface features that are both common and unique to the surfaces of the Moon and Mars, then perhaps Earth too has its own idiosyncratic features.

Tornadoes, dust devils and waterspouts

To understand the wide variety of atmospheric vortex features we have to take step back and look farther afield. Such features are the result of processes not only at a global level but at a heliospheric level.

“In the electrical model of the solar system, all planets must contrive to supply electrons to the positively charged Sun.” (2) In this particular instance we are talking about relative potentials, the Sun is highly negatively charged but as interstellar space carries a greater charge in the negative sense, the Sun acts as if is positively charged. Juergens had suggested that planetary magnetospheres intercepted electrons bound for the Sun, the magnetospheres then re-emitted surplus electrons to participate in the solar discharge: “The continuous arrival of positively charged cosmic rays on earth suggests that our planet carries and continually renews a strong negative charge. Indeed, experiments performed some years ago by Quinn and Chang indicate, in spite of the experimenters’ pointed disclaimer, that the earth behaves as a secondary cathode in the solar discharge…I would speculate, therefore, that the earth’s negative charge represents that of electrons intercepted on their way to the sun by earth’s sheath-like tail, and that this charge is built up to a point where the earth re-emits electrons into the solar discharge.” (3)

This complex interaction is what powers Earth’s weather systems, elsewhere I suggested that thunderstorms that form during the night demonstrate that the Earth sources electrons from the magnetotail (4), and part of the charge exchange process is achieved through lightning activity and vortex (i.e. tornadoes, waterspouts, dust devils) activity.

“Usually the cloud to ground discharge takes the form of the multiple sparks we call lightning. However, in some parts of the world the lightning switches to the slower discharge of the tornado. Then, instead of the electric charge rushing directly between the ground and the cloud along a thin lightning channel, it is constrained by powerful electromagnetic forces to rotate in a long, thin cylinder or vortex. Measurement of the magnetic field and earth current near touchdown of a tornado shows that it is electrically equivalent to several hundred storm cells. It is this concentrated electrical power in the central vortex that creates damage far in excess of that possible for a simple wind vortex. It also explains the burnt surfaces and objects sometimes found after the passage of a tornado.” (5)

The destructive nature of tornadoes is well known, this account from Rouen, France in August 1845 also provides an insight into the havoc caused by the electrical nature of tornadoes: “The trees in the vicinity were flung down in every direction, riven and dried up for a length of from six to twenty feet and more. While clearing away the ruins, in the attempt to rescue the unfortunate people buried beneath them, it was noticed that the bricks were burning hot. Planks were found completely charred, and cotton burned and scorched, and many pieces of iron and steel were magnetized.” Some of the corpses showed traces of burning, and others had no visible cuts or contusions, but seem to have been killed by lightning. Workmen who were hurled into the surrounding fields, all agreed that they had seen flashes and had noticed a strong smell of sulphur. Persons who happened to be on the adjacent heights, alleged that they saw the factories wrapped in flames and smoke as the cloud enveloped it.” (6)

In the above we see evidence that certain materials displayed a remanent magnetism after the passage of the tornado. Is it possible that in the past electric discharges, taking the form of immense vortexes, reshaped parts of the Earth’s surface and left evidence in rocks that were susceptible to magnetization?

Earth’s ‘Hexagon’

Antarctica is surrounded by what consensus geology considers being a more-or-less continuous ‘spreading centre’. (7) The problem for Plate Tectonicists is that there is no corresponding ‘subduction zone’ to remove the supposedly newly created oceanic crust. Furthermore, the polygonal shaped ridge surrounds the Earth’s North Magnetic Pole (the South Magnetic Pole being in North America), looking out into the solar system we see a similar polygonal feature, this time an atmospheric feature, surrounding the North Magnetic Pole of Saturn- the famous Hexagon.

Radiating and trending northwards from the circum-Antarctic ‘spreading centre’ are a number of ridges or other ‘spreading centres’ including the East Pacific Rise, Central Indian Ridge, Ninety East Ridge and the Mid-Atlantic Ridge. Where such ridges make landfall we find deep canyons on the continental shelves farther inland we see elevated plateaus and mountain ranges but where did the material originate that forms these features? Fossil remains in areas such as the Colorado and Himalaya Plateaus usually consist of “graveyards” a strange mix of marine, lacustrine and terrestrial animals and plants, of course consensus geology sees these deposits as having formed over millions of years. Over time as the landscape constantly changed animals of the land, sea and air met their fate at the same locale- but what if this assumption is incorrect? What if the “graveyards” are something else altogether? What if the “graveyards” formed as the mountains themselves were formed? They would then be testament to a cataclysm. If ‘spreading centres’ and ridges were formed electrically do extraterrestrial analogues exist?

Earth’s Tiger Stripes

“The south polar region of Enceladus has long been a source of fascination to planetary scientists since jets of water vapour and icy particles were found to spew from vents along the moon’s distinctive ‘tiger stripe’ fractures, and now evidence has been presented to suggest that Earthlike plate tectonic activity is in action.

“The science team liken the spreading to Earth’s mid-ocean ridges where volcanic material wells up and creates new crust, but with one major difference: the spreading on Enceladus is almost all in one direction.”Asymmetric spreading like this is unusual on Earth and not well understood," says Paul Helfenstein, Cassini imaging associate at Cornell University. "We are not certain about the geological mechanisms that control the spreading, but we see patterns of divergence and mountain-building similar to what we see on Earth, which suggests that subsurface heat and convection are involved."”(8)

Cassini mission scientists noted how similar in appearance Enceladus’ ‘tiger stripe’ fractures appear to Earth’s ‘sea-floor spreading’ features going so far as to make a direct comparison of such features as spreading ridges, transform faults and an offset spreading centre. On Enceladus the ‘tiger stripe’ terrain, which continues to emit jets of warm water vapour and organic compounds, are analogues of Earth’s ‘spreading centres’ and their associated volcanic activity including black and white ‘smokers’, both are weaker relics of earlier massive electrical activity that once carved and punctured their respective surfaces.

We can now piece together the pole-to-pole discharges that reshaped Earth’s surface resulting in Earth’s ridge and mountain systems.

Pole to Pole

In 1963 astronomer Thomas Gold considered the consequences of the Earth’s magnetosphere encountering an exceptionally large solar outburst. According to Gold: “The earth’s magnetic field could clearly not hold up the incoming gas, and it would indeed drive down to the atmospheric level where the gas pressure can resist the further flow. At that level the atmosphere is dense and the ionization that could be maintained would not result in a good conductivity. The incoming gas bringing its strong field into the virtually insulating atmosphere would then result in very large electric fields so directed that the resulting currents would maintain those fields. But in the atmosphere this can be done only by electrical breakdown. Since the ground is a good conductor such a breakdown is likely to take a path of breakdown through the entire thickness of the atmosphere on each side of the magnetic cloud being pressed in, and through the body of the earth from one site of breakdown to the other … This breakdown would be in the form of a series of sparks, burning for extended periods of time and carrying currents of hundreds of millions of amperes.” (9)

Gold had considered an exceptionally large CME (coronal mass ejection) but what other scenarios could be envisaged that could produce similar currents, scenarios that are currently beyond mainstream science thinking? A drastic change in Earth’s electrical environment for example?

Thunderbolts contributor Andrew Hall has done some excellent research work looking at the formation of mountains (10) positing the role of the atmosphere in their formation. (11) Elsewhere I have suggested that the Earth originally displayed a hemispheric dichotomy, an oceanic Pacific hemisphere and a continental Indo-Atlantic hemisphere. (12) Although termed ‘continental’ we can picture the Indo-Atlantic hemisphere as containing lakes and inland seas as we see on the continents today. Combining both approaches we can trace the path of the discharge current travelling south to north excavating the Indo-Atlantic hemisphere as it goes. Machined and pulverised sediments are pushed away by a powerful Lorentz Force, piling up ahead of the discharge, leaving behind a newly formed magnetized basaltic ridge and fractures filled with fresh lava (The rocks of the Mid-Atlantic Ridge (MAR) are often portrayed in Plate Tectonic cartoons as being entirely igneous, this is not the case. Limestone containing shallow water fossils has been recovered from the MAR, the limestone is of a chemical variety that has been altered by a process that must have taken place subaerially). Outpouring subsurface water from the fractured crust gradually filled the newly formed basin (extensive subsidence would have followed as Earth’s surface gravity increased due to an accumulation of charge).

Forests in the path of the discharge are burned and petrified- disparate ecosystems are thrown together for future palaeontologists to ponder. As the current pushes more and more watery sediment strata form and are folded in situ eventually the mass of the load seems to have exceeded the motive power of the discharge which now, as in the earlier reports of the effects of tornadoes, begins to ‘bake’ and erode the newly formed assemblage perhaps partially melting not only the sedimentary mass but the basement rock as well. The Rocky and Himalaya Mountains were probably formed this way. Only one discharge channel stretches from ‘pole to pole’, the Mid-Atlantic Ridge which terminates in the Arctic Ocean basin, the largest sedimentary basin on Earth. (13)

Fire and Ice

Writing in 1976 on the subject of electricity in astronomy Eric Crew observed: “Lightning causes the material in the discharge channel to be compressed and accelerated in the direction of the negative charge. (The free electrons moving in the opposite direction having relatively little affect on the flow of material). This jet of hot gas contains water vapour and if it is directed into the upper atmosphere, a streak of mist or ice particles will be formed, possibly several km long. On its downward path into the denser atmosphere, the particles bunch together and an ice lump may fall to the ground there are many such cases reported and even stones may have been formed when the lightning is in clouds of volcanic or other dust.” (14)

In the scenario suggested here, with extended and catastrophic electrical activity encircling Antarctica radiating out toward the Arctic we can ask the question- did this postulated electrical discharge event(s) rapidly encase both polar regions in ice?

If lightning can also form stones from dust what are we to make of ice-age ‘dropstones? Recently, Michael Rampino, a Professor of Biology at NYU, has suggested that deposits once considered being ancient ice-age tillites are actually impact debris. (15) In the scenario suggested here such tillites and ‘dropstones’ would be neither- they would be products of intense electrical activity- electrified stones falling from the dust choked atmosphere into soft sediment.

Wrong Turn?

Shortly after the discovery of sea-floor magnetic anomalies geologists noted that the “…lineations strongly resemble stress patterns that appear in certain plastics.” An electrical cause was briefly considered, “…a complicated system of electric currents in the crust and the ocean could account for our lineation. Not a shred of other evidence supports such an idea, however.” (16) That was in 1961, today even mainstream science to some degree acknowledges Earth’s electrical nature. Perhaps in the past it was even more so, so much so that electrical scars were left on the floors of new ocean basins.

With hindsight and knowing what we know today about the electrical nature of the solar system, would geologists, if they were equally aware in 1961, have explored an electrical interpretation of sea-floor magnetic anomalies further? Perhaps the New Global Tectonics revolution would never have happened and a more accurate picture of Earth’s electrical nature would have been painted.

Of Geotectonic Wizards And Geomagnetic Reversals

In 1978, a year before his untimely death, Ralph Juergens unsettled the settled science of sea-floor spreading. In a little known work Juergens pulled back the curtain on the great and powerful Oz-like myth of sea-floor spreading and exposed it to be nothing more than smoke and mirrors.

Sea-floor magnetic anomalies had an explanation without the need for sea-floor spreading but the mobilists reinterpreted the data, data that was eventually used to ‘prove’ the New Global Tectonic paradigm- Plate Tectonics.

Our story begins in 1952 with the discovery of magnetic anomalies in the Pacific Ocean, “…when Ronald G. Mason of the Scripps Institution of Oceanography towed a magnetometer off the stern of a ship sailing from Samoa to San Diego. The instrument revealed an intriguing series of magnetic anomalies -- field intensities higher or lower than theory would predict -- along the track of the ship. It appeared that the anomalies were arranged alternately positive and negative -- high and low magnetic intensity, respectively -- with remarkable consistency.” (1)

Then, “…in 1955 the U.S. Coast and Geodetic Survey assigned the ship Pioneer to a research project in deep water off the West Coast. It was to steam along east-west track lines five miles apart, holding to the prescribed course within 150 yards.” “By late 1956 the ship had surveyed a strip of ocean several hundred miles wide extending from Mexico 1,400 miles north to the Queen Charlotte Islands, off British Columbia.” (2)

Over the next three years the survey was gradually extended farther out into the Pacific Ocean and by the early 1960’s geophysicists wondered what process could possibly cause or have caused such magnetic anomalies.

Notice that at this time magnetic anomalies are simply measured as regions of different magnetic intensity, even so there is more to this interpretation than meets the eye, as Juergens points out: “The investigator averages all the highs and lows in the readings along a single profile, then subtracts the result from each of them "in order to define positive and negative anomalies" (emphasis added).This manipulation puts "zero" -- a datum line separating positives from negatives -- squarely through the middle of the profile. He does not ask: What if I were to lower the datum enough to eliminate half the negative anomalies defined by my procedure, or raise it enough to eliminate half the positive anomalies?” (3)

The arbitrary definition of the newly discovered sea-floor magnetic anomalies didn’t stop the sea-floor spreaders and, “In 1963, F. J. Vine and D. H. Matthews of Cambridge University proposed that the peculiarly systematic magnetic features, mapped as positive and negative anomalies by all workers up to that time, were actually alternating strips of crustal rock magnetized with normal and reversed polarity.” (4)

Vine and Matthews had utilised data from a survey of the Carlsberg Ridge, returned as part of the International Indian Ocean Expedition, the surveyed region was mountainous and certain relationships were observed, “…[1] long-period anomalies over the exposed or buried foothills of the ridge; [2] shorter-period anomalies over the rugged flanks of the ridge; [3] a pronounced central anomaly associated with the median valley.” (5) The authors noted that the “…central anomaly can be reproduced if it is assumed that a block of material very strongly magnetized in the present direction of the Earth’s field underlies the median valley and produces a positive susceptibility contrast with the adjacent crust.” and a “…trough of negative anomalies, flanked by steep gradients, separates two areas of positive anomalies. The trough of negative anomalies corresponds to a general depression in the bottom topography which represents the median valley of the Ridge. The positive anomalies correspond to mountains on either side of the valley.”(6)

Up to this point the authors refer to positive and negative anomalies, acknowledging that “topographic features are capable of producing anomalies”, there is no mention of reversed magnetization, indeed, the authors note “…the effect of a body magnetized in the present direction of the Earth’s field is to reduce the strength of the field above it, producing a negative anomaly over the body and a slight positive anomaly to the north.” However, by the fifth paragraph a subtle sleight-of-hand has occurred: “Two comparatively isolated volcano-like features were singled out and considered in detail. One has an associated negative anomaly as one would expect for normal magnetization, the other, completely the reverse anomaly pattern, that is, a pronounced positive anomaly suggesting reversed magnetization.” (7)

And there it is, from that point on, positive and negative magnetic anomalies that suggested normal and reversed magnetization were forever ‘normal’ and ‘reversed’ magnetization. The anomalies may have suggested ‘normal’ and ‘reversed’ magnetization but where the authors influenced by a preconceived bias? Did they make the data fit the theory?

“The theory is consistent with, in fact virtually a corollary of, current ideas on ocean floor spreading and periodic reversals in the Earth’s magnetic field.” (8) It would appear that a consensus already existed.

However, as Juergens pointed out there was no real need for magnetic reversals, “… it was well-understood, as predicted on theory and verified again and again in continental magnetic surveys, that normally magnetized geologic formations could account for the entire ocean-bottom picture, imposing negative as well as positive anomalies on profiles. Vine and Matthews themselves conceded this. Each magnetized formation is itself a magnet. Its field lines, like those of the earth, emerge from one pole, loop in all directions all the way around, and re-enter at the other pole. And as the lines make their loops, they reinforce the earth's field here, oppose it there, giving rise to positive and negative anomalies.

“The magnetic latitude of a magnetized formation determines how steeply its axis will be inclined with respect to the ground surface (assumed level). And this, in turn, influences the form of the anomaly curve it will impose on a profile. Reinforcement (positive-anomaly build-up) will be more pronounced at higher magnetic latitudes, and opposition (negative-anomaly build-up) at lower magnetic latitudes. But anywhere on the globe most magnetic profiles will display both positive and negative anomalies in close association and traceable entirely to normally magnetized rocks.” (9)

Vine and Matthews did concede that point, “It is appreciated that magnetic contrasts within the oceanic crust can be explained without postulating reversals of the Earth’s magnetic field; for example, the crust might contain blocks of very strongly magnetized material adjacent to blocks of material weakly magnetized in the same direction. However, the model suggested in this article seems to be more plausible because high susceptibility contrasts between adjacent blocks can be explained without recourse to major inhomogeneities of rock type within the main crustal layer or unusually strongly magnetized rocks.” (10)

So, it would seem, that the entire sea-floor spreading hypothesis was ‘confirmed’ by a more ‘plausible’ opinion and an assumption or belief of ‘reversed’ magnetization, yet only two years earlier “…Arthur Raff favoured an explanation according to which "the strongly positive anomalies are produced by ribbons of highly magnetic, volcanic basalt that flowed into previously formed channels and solidified. [Of all the models considered,] the strips of solidified lava seem to us the most likely." Earlier in his article he had noted that "the right pattern of stress," even without a flow of molten rock, might explain the lineated anomalies, "since the magnetization of rocks varies under stress." But he rejected this piezo-magnetic explanation, characterizing the necessary forces as "highly unusual and unlikely." Nevertheless, he reasoned that the lineations must reflect "some sort of ridged or striated pattern in the crustal rock, obscured by overlying sediment." He added that the magnetic anomaly maps bear "a striking resemblance to the patterns that appear in Bakelite and Lucite when they are placed under stress. This suggests that the present structure is the fossil record of ancient stresses."” (11)

Magnetic anomalies had an alternative explanation one that consensus geology refused to entertain- a possible catastrophic one as Juergens reminds us, “Whatever the actual process or processes by which parallel features flanking oceanic ridges became anomalously magnetized, it appears most likely that powerful tectonic forces were involved. The overall picture, divorced from the ill-fitting frame of sea-floor spreading, evokes explanation in terms of Worlds in Collision and Earth in Upheaval.

“Somehow, today's well-schooled earth scientist finds it within himself to accept the startling notion that the geomagnetic field has flipped over hundreds of times since the Cretaceous Period, which immediately preceded the present Cenozoic Era in Geologic time. He subscribes to this, apparently, on the assurances of a few specialists claiming to know how an unelectrified earth can generate a magnetic field and, even more, how such a field can be reversed. Yet when Velikovsky argues, on the basis of historical testimony, archaeological evidence, and sound physical principles, that the geomagnetic field has been suddenly reversed on more than one occasion in historical times, the earth scientist looks the other way.

“We have seen that a close look turns up little, if any, evidence from the sea bottoms pointing to geomagnetic reversals, and none at all for sea-floor spreading. To the contrary, patterns of rock magnetism beneath the oceans point to global upheaval and turmoil.” (12)

Sea-floor spreading the keystone of not only Plate Tectonics but also of Expanding Earth theories has entered the geological hall-of-fame, so certain are geologists of its validity that it is taught as fact to geology students and non-specialists alike, yet the research on which it stands, that of sea-floor magnetic anomalies and their interpretation is subjective. The reality may be very different- a catastrophic one.

“The relationships between the anomalies and mid-ocean ridges are fully compatible with the idea that the rifted ridges are the scars of violence done to the earth's crustal fabric. The suggestion that contortions of the crust may be completely masked by overlying sediments was substantiated in the early 1960's through echo soundings; the investigators, Maurice Ewing and several colleagues of Columbia University's Lamont Geological Observatory, concluded that "horizontal currents" -- a euphemistic term for catastrophic water sloshings of the kind described by Velikovsky (Earth in Upheaval, "A Working Hypothesis," and elsewhere) -- must be held responsible for so emplacing sediments as to erase completely all superficial evidence of the "remarkably rugged" basement complex revealed by their studies.” (13)

Having exposed the great and powerful Oz-like myth of seafloor spreading Juergens left the door open for a catastrophic interpretation, one of electrical discharges, storms and dare I say it- tornadoes!
