Basically a great world scale flood is mentioned in the ancient mythology of a vast number of different separated cultures on different continents, though this is not accepted by most of todays scientists I will in this blog entry explore the possibility of a real global flood and how other theories like crust displacement, the wobble of Earths axial tilt and the accepted known asteroid strike on the North American continent 13000 years ago would fit into a thesis on a rapid global scale flooding, as partially described by our ancestors.

Rapid Crust Displacement Theory and Pole Shift 

Not to be confused with magnetic polar shift which does not involve any actual change of the crust and locations of the poles but a switch in magnetic polarity causing the magnetic north and south poles to switch, as seen in the geological record of the magnetic rocks in the crust.

In this theory the during the end of the last ice age the glacial ice cap that covered most of the Northern Hemisphere land-masses became so massive that it caused the crust of the Earth to shift, causing all continents to shift in position compared to the liquid layers of magma that Earth's crust float on-top of, this shift would caused the European part of Eurasia shifted more south and with the Asian parts like Siberia moved closer to the North pole, shifting the continent of Antarctica making it totally covered under todays South Pole ice-cap and this shift are also theorized to cause massive earthquakes and wide spread tsunamis  all over Earth, and thus being one possible origin to the global flood myths. (Read Cause and Dangers of Tsunamis for more on tsunamis)

This theory should be simple enough to prove or disprove based on Earths known hot spots like the super volcano of todays Yellowstone Park, and the hot spot that fuels the volcanos of Hawaii, with a shift in crust these hot spots would shift location compared to the crust since a hot spot are anchored to the deeper core of Earth and do not follow the crust movements but punches holes in Earth's crust as it passes over the hot spots, causing new volcanos to form like the chain of the Hawaiian isles that one can follow as a chain of ancient volcanos past Midway and even all the way up to the isle's of the Bering Strait.

Earth Has a Wobbling Axial Tilt

The Earth's wobble is widely accepted in scientific communities, this wobble is used as one of the current theories to explain how ice ages and interglacial hot periods like the one we are living in now fluctuates over millions of years according to Earth's axial tilt. The axial tilt controls how much solar radiation and seasonal variation the different parts of Earth receives, the farther away from the equator of Earth one are situated, the greater the effect the axial tilt have, according to this theory Earth's wobble changed slowly over time and thus should not cause any rapid changed like a global flood, though it would cause coastal lines to emerge up dry and submerge as the waxing and waning glacial and interglacial cycles troths along.

Approximately 13000 years ago an asteroid hit the Glacial Ice of Northern America

In the end of the last ice age, there are evidence of a rapid change that caused a miniature ice age to cloak Earth for a few thousand years before it returned to the hotter interglacial climate that we still see today. Now this impact event was big enough to almost instantly melt a large portion of the glacial ice that was still present in Northern America 13000 years ago.

This same impact cloaked the Northern Hemisphere with a large amount of dust blocking out the Sun, causing rapid cold to overtake Eurasia, and some parts like Northern Siberia are still kept colder than it was before the event happened 13000 years ago. This also caused a large amount of low laying land and coastal areas to turn submerged within a short period of time, it also caused a swift change in the ocean jet streams that regulate how much hot and cold water are shifted around the Earth, causing Northern Europe to turn hotter while Northern Asia like Siberia turned colder, and this is still in effect 13000 years later. 

It also would have changed the heat conversion in the Southern Hemisphere possible causing Antarctica (which some ancient world maps seem to depict in detail according to its still glacial ice covered coast lines) to turn even colder than it was back 13000 years ago until this day, also in addition to flooding low laying islands and costal areas on a global scale. 

The asteroid impact very likely also triggered a lot of Earthquakes that could have added tsunamis to the global serial floods, and possible be the origin of the worlds flood myths.

To conclude

So my personal opinion and suggestion is that even though an asteroid strike could possible but unlikely also caused a crust displacement, and larger than usual change in axial tilt of the wobble, it could alone have been the smoking gun that proves that our ancestors actually did experience great floods before the time of written history, and this was carried on for generations before they finally were placed in stone and other media of writing.

The cause and dangers of Tsunamis

Santorini, Greece

A number of natural phenomena's can cause tsunamis among these: underwater avalanches, like the Storegga avalanche and the tsunami it caused outside the coast of Norway in 6100BC, meteors and comets striking water, explosive submarine volcanic eruptions and most commonly earthquake tsunamis like the 8.1 earthquake Tsunami of 2009 in American Samoa, the strongest ever recorded 9.6 quake of 1960 tsunami and the 8.8 quake of 2010 tsunami both in Chile, to compare the 2nd strongest quake recorded was at 9.3 of 2004 in Indonesian water, this was the one that caused the great tsunamis of december 2004 which is the most devastating one in modern times.

Underwater and costal avalanche slides

That avalanches could cause major tsunamis is still fairly unknown among most people, this type of tsunami could also be harder to detect since the avalanches could be triggered by minor tremors which then cause the avalanches, this is also why tsunamis could be so dangerous, since the size of a quake does not tell you what it has triggered of small and large underwater avalanches, thus proving this natural phenomena's erratic nature. One of the largest known tsunamis known in fairly recent time is the Storegga avalanche tsunami outside the coast of Norway dated to 6100BC, this tsunami was caused when a submerged landmass the size of Iceland slid into deeper water causing some of the largest tsunami waves in the last 10000 years and it's effect is still found if one know what to look for in the British isles, Ireland, Scotland, Shetland, Iceland, Norway, and Greenland.

Earthquake tsunamis

Earthquake is by far the most common cause of tsunamis, often the earthquake trigger submarine slides which could cause massive tsunamis even stronger than one expected from the raw Earthquake itself, other times the forces of the Earthquake itself causes minor tsunamis or only very local tsunamis like the quake outside of Chile in 2010, this earthquake even though it was a 8.8 caused massive tsunami waves in Chile but only minor waves across the rest of The Pacific Ocean, like in Hawaii which was put on a tsunami warning, closed down stores, highways and evacuated people from small buildings and in high rises below 4th floor. The 9.5 Chile earthquake of May 22, 1960 on the other hand caused massive damages in Hawaii, wiping out the beach line of Hilo on the island of Hawaii.

Below are some video footage from the tsunami that struck American Samoa after it was struck by a 8.1 earthquake, 29th of September 2009.

Submarine volcanoes and volcanic isles

Another very destructive type of force that cause tsunamis is pyroclastic eruptions of submarine volcanoes, usually submarine volcanoes or even volcanic islands are stable and calm but sometimes if they build up a caldera and store up kinetic energy they could suddenly without warning erupt causing tsunamis even more destructive than those caused by earthquakes. One example of this is when the Greek island Thera erupted violently in 1500BC which caused the end of the Minoan culture, and even possible was the mythical Atlantis, Thera is now known under the name Santorini.

The crater caused by the volcanic eruption of 1500BC is still visible today as on this landsat satellite image of the island of Santorini, Greece.

Tsunamis caused by Meteors and Comets

With out a doubt these have would be the most devastating types of tsunamis, if a large meteor or comet hit the open oceans, which it most likely would due to the fact that about 71% of earth is covered by oceans, it would actually be far worse for meteors or comets to hit the oceans rather than if it hit a large continental land mass because of the direct destructional force caused by having the kinetic energy transfered in the sea. Luckily most meteors that hit Earth are too small to cause damage, and there is actually something our governments could do to take preventative measures against major comets and asteroids becoming extinction event class meteor strikes.
