EFFECTS OF THE MANSON IMPACT STRUCTURE

The Manson event was an unimaginable catastrophe. The impact of the enormous meteorite caused destruction equivalent to approximately 10 trillion tons of TNT. Everything within 130 miles of the point of impact was instantly engulfed in flames. Trees were toppled and standing vegetation was devastated within 300 miles of the impact site. It is also believed that most animals as far as 650 miles away did not survive the Manson impact, and dinosaurs 800 miles away would have been knocked off their feet.

The Western Interior Seaway was home to many forms of marine vertebrates, which would have been greatly disturbed or killed by giant shock waves and possible tsunami-like waves. The seaway’s habitats would have been so disrupted as to cause the death of thousands of marine creatures. To support this theory, scientists have found evidence that certain lineages of fish, mosasaurs and marine turtles, including the Archelon, mysteriously vanished from the Western Interior Seaway during the approximate time of the Manson impact event.
