IMO, it's more likely the result of rapid plate drift and fracture due to the massive pressure waves generated. :)
Not meteor strikes - the objects were too large. Read through the slides carefully. The rapid drift was caused by the simultaneous impacts = source of requisite force to move the continents. A massive pressure wave could have contributed to the transits of Africa and India, but the source of that wave was the impacts.
Your area of interest in the Caribbean was created by the northern object’s transit, and so the depth is no surprise because of the object’s massive size.
As I said in the previous post, geologists have it all wrong. The garbage that has been published as a consequence of accepting continental drift as scientific truth is sad though creative.... For example: Snowball Earth could not have happened.
It’s not easy creating a paradigm shift, but I am trying. The slide presentations are a repository while I pursue acceptance.
