1) when did this happen 2) which impact is this referencing - we know there were multiple tsunami events hitting the coast of WA 3) are there Aboriginal stories regarding a massive flood 4?) why couldn't the coast of WA have been under water then rapidly elevated?
All of these questions are actually answered in our other videos, but I am happy to answer again here. 1, Approximately 5000 years ago, based on the dating of barnacles found on displaced granite boulders found along the WA coast. See: www.researchgate.net/publication/37359410_The_Holocene_ paleo-tsunami_history_of_West_Australia See our episode 4. 2, Not an impact. The origin of these tsunamis appears to be related to undersea landslides on the continental shelf off the coast of the Cape to Cape region. See our episode 5. 3, Yes there is a story regarding the inundation of the Rottnest plain which connected the island to the mainland. See our short episode dated: 26/09/2024. 4, The Swan Plane in Western Australia is tectonically inactive. There have been no tectonic or isostatic changes to the relative crustal height of this coastline for millions of years. Any relative changes in sea level therefor have to be entirely eustatic, that is, entirely related to global sea level changes. See our episode 4. Reference: The Geology of Australia by Henderson and Johnson.
Ah. No. There is no such thing as the Burckle impact. There is no evidence of a 6 kilometre asteroid impacting planet earth 5000 years ago. This was a continental shelf landslide. Probably triggered by a smallish earthquake.
thank you.
cool - thanks

@@WATsunamianything to do with New Zealand. Don’t they have an active plate.
@@MrIrish1 The origin of WA tsunamis is undersea landslides on the continental slope, mostly just off the coast of the Cape to Cape region.
I love these videos.
@@frucklerbullpit thank you
