5000 years ago {I think it was 4300 years ago}, a comet broke apart into three pieces upon entry into Earth {atmosphere}. The largest piece, smashed into the Indian ocean, with the other two smaller pieces landing in different areas of the Pacific Ocean. The Indian Ocean impact, was incredibly disastrous. It landed in a very deep part of the ocean, and, as a result, it released a truly monstrous mega tsunami during impact. This tsunami was so disastrous, that 600 foot high {chevron-shaped ridges} were built in Madagascar in the blink of an eye, when massive amount{s} of churned-up sediment, that was carried by it, got deposited in truly vast quantities here, and everywhere else that this tsunami stuck, too, including very, very far places, such as Tasmania. When this Mega tsunami struck, it did so with such force, that it severely eroded entire cliff faces, and left deep gashing scars in the land, which document the direction {of} flow. Along with this, it also deposited something known as seismic chevrons, which are arrow-shaped hills of deposition, that were left after the wave had slammed into Australia.
When it began to recede, all the material it carried was just dropped where it {ended}, and the water move{d} out, but the sediment remained. Because of this, massive layers of sand were deposited, and even though 5000 {4300} years have passed, you can still see many places where this tsunami impacted. In this full length documentary, the 3 episodes that cover this topic were combined and as a result we start in Perth, before moving onto Tasmania, Victoria, then we head west to South Australia, before ending our journey in the far northern tip of Western Australia. We go through bit by bit, documenting the evidence of this event, and as we hit South Australia, the evidence really begins to ramp up. I teach you how to identify chevrons, what they are and how they form, and I also cover the difference between chevrons and aeolian {wind} processes, including what the intertwining of these two looks like.
I have found what I consider to be extremely strong evidence regarding the existence of chevrons in Antarctica. These chevrons occur en masse, in the direct firing line that a mega tsunami would travel, post-Burckle crater impact. When the comet that created the Burckle Crater struck a deep section of the indian ocean, the mega tsunami that it created travelled outwards from the epicenter in a 360 degree direction, hitting every single shoreline of every continent that was near. Antarctica was no exception to this, but I originally thought any evidence of this event would either be buried, or long gone. I was wrong. Today we'll look at the compelling evidence I found on the shorelines of Antarctica.
The very same 200 odd meter high mega tsunami wave that hit Australia, also hit here, and after spending so many days using this simulator to read Australia, Indonesia's, and the rest of the impacted worlds' tsunami evidence, I spotted these shapes with ease. These shapes both begin, and end, inline with the Burckle Crater impact. With the damage and chevron deposition ceasing right at the point that is outside the line of travel from the epicenter that this Tsunami would've travelled, I believe this is the first time evidence of this event has been linked to Antarctica. If not, I stand corrected, but if so, that's pretty amazing.
You certainly wouldn't be able to make these features out with confidence on {}either Google maps, or Google Earth. But this simulator shines yet again, when detecting the chevrons, purely because of it's incredible topographical accuracy and succinct attention to detail.
When a comet collided with the deep section of the Indian Ocean around {4300} years ago, the mega tsunami that was generated absolutely inundated and decimated the shorelines of every continent that was within the direct reach of the impact crater.
CHEVRONS. When tsunamis reach inland as far as they can go, they stop motion briefly and sediment falls out and deposits in the shape of chevrons, or V-shapes, that point away from the source of the tsunami. Scientists found the source by going away from the V-shapes from several locations around Indian Ocean shores to where they intersected, which was the location of Burckle Crater. The author says severe rain storms followed the tsunamis, making the flooding much worse.
Tasmania is a large island south of Australia. Small islands southwest of Tasmania bore the brunt of the tsunami that hit Tasmania.
The above image shows chevrons on the small islands.
And the above image here shows chevron locations on the southern tip of Tasmania, just beyond the small islands.
This image above shows more chevrons in the same area from a higher vantage point.
New Zealand was also hit.
Above image shows where the largest part of the comet struck to form the Burckle Crater in the Indian Ocean and the possible sites in the Pacific where the two smaller fragments hit.
The author says by hitting ocean waters the impacts vaporized millions of tons of water, which produced torrential rain and hurricane-force winds that lasted for weeks, devastating forests and inundating valleys and plains. Earthquakes and volcanic eruptions were also likely triggered by the impacts.
The above image shows Iraq and mountain ranges along the east side of the Persian Gulf and both sides of the Gulf of Oman, also the direction the tsunami hit the Gulfs. The mountains would have acted like a funnel to increase the height of the waves, so that they could inundate Mesopotamia, now in Iraq. The tsunami might have reached the foothills of the mountains in Turkey where Noah’s ark is said to have landed, but I think that event more likely occurred earlier during the Younger Dryas event. The author also suggests that the tsunami went up the Red Sea and inundated Egypt and the pyramids.
It's been some time since we last explored the Africa Mega Tsunami Hypothesis, a theory proposed by Bright Insight. Today, we're diving back into this intriguing subject. Bright Insight suggested that a major impact event in the Mediterranean would significantly affect water flow and the areas impacted. This blog post will delve into why this theory holds water. You can also find more about this on my website, ozgeographics.com.
To better understand the potential effects of a major tsunami originating from the Mediterranean and heading south towards Africa's northern coastline, we'll break down Africa's vast landmass. This will help us visualize the potential water flow in the event of a tsunami.
First, let's consider a horizontal cross-section of Africa, from Mauritania to Somalia. This perspective allows us to estimate the land's height and predict the water flow direction in a tsunami scenario. The average terrain height here is approximately 300 meters or around 1000 feet above sea level.
A near-vertical cross-section from Morocco to Lagos reveals a significant mountain range extending upwards of two kilometers at the northernmost tip of northwestern Africa. Beyond this mountain range, the topography is also around 300 meters or 1000 feet above sea level. This suggests that the tsunami wave wouldn't need to be as large as previously estimated to cause significant damage.
The aftermath of such a tsunami would likely leave behind visual evidence in the form of chevrons. However, this remains a hypothesis until we can conduct on-ground investigations. It's crucial to keep an open mind and consider factors like aeolian processes and ongoing sedimentation alterations.
The ideal investigation site would be a lower-lying area in the Sahara's central region, where sedimentation could accumulate. If a flood event occurred, the receding wave would likely leave behind trapped sediment in this area. By taking a drill core and analyzing the layers in a lab, we could identify any foreign materials from the Mediterranean Sea or any metals associated with an asteroid impact.
In one of my previous videos, I discussed potential major chevron-like shapes southwest of Tunisia. These shapes, contrary to the direction of the prevailing wind, suggest a possible tsunamigenic origin. The area with the largest chevrons was the lowest-lying region, around 341 meters or 1119 feet above sea level.
If an impact similar to the one I suggest occurred in the Mediterranean, Bright Insight's hypothesis holds water. We have one area of Africa where chevrons are being deposited in a directional manner contrary to the prevailing winds in the Northwest. This anomaly suggests the need for further investigation.
The findings of this study indicate that a tsunami above 350 meters would likely tear through Africa and exit out the west and southern part. It would pass over the Richat Structure, an area Bright Insight believes to be Atlantis. However, I find Randall Carlson's hypothesis more compelling in this regard. {I think Carlson decided that the Azore Islands was Atlantis when sea level was much lower.}
The Richat Structure, an astonishing place, would have been directly in the tsunami's significant drainage pathway. If chevrons are present beyond this point, where the average elevation rises to around the 500 to 600-meter level, we can begin to estimate the height of this hypothesized mega-tsunami.
This blog post marks the continuation of a series where we will conduct many geological deep dives, utilize geophysical techniques, travel to various locations, and scour through the literature to see if any possible link can be found to support this hypothesis.
Stay tuned for more exciting explorations into the Africa Mega Tsunami Hypothesis. Until then, thanks for reading!
Above image is of north Africa in the Sahara. The chevrons indicate a tsunami.
This image above helped the author determine that the impact occurred where the red circle is, because the white-shaded area shows signs of tsunami scouring, while the shadow effect area shows no signs, because of the mountains that blocked the tsunami, but the area in the white outline shows signs again, because the mountains did not block the tsunami there.
