5000 years ago, a comet broke apart into three pieces upon entry into Earth. 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 mountains were built in Madagascar in the blink of an eye, when massive amount 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 the 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 landed, and the water move out, but the sediment remained. Because of this, massive layers of sand were deposited, and even though 5000 years have passed, you can still see many places where this tsunami impacted.

The entire western coast of Western Australia, and the southern coast of it, had towns that are built ontop of the sediment released by the mega tsunami, as this entire section of land was deeply affected by the 180 odd meter waves that struck here with savage force. Stretching inland as far as 30km in some places, and even further in others.

In this video we take a look at the present day evidence and depositions left over by this mega tsunami as we slowly move west from Victoria, into South Australia, then finally into Western Australia, where we'll journey all the way north to the very top of the continent, where the mega tsunami waves finally end.

This is episode three of the large series I have planned that covers the mega tsunami chevron deposition left over following the mega tsunami. And I intend on travelling to all the affected continents to note the damage, and to cover the massive deluge that occurred later on, which is dated to have coincided with the onset of the biblical flood stories which are documented by over 150 different cultures worldwide.
