"The impact I use is the one described in Otto Mucks
book Secretes of Atlantis. He places it in the Atlantic
ridge with "splatter" in Charleston USA."
Unfortunately, the alleged craters of Otto Muck suffer from the same problems that Andres’ hypothesized craters. First, the circular features, which Muck identified as "impact craters" are nothing more then artifacts of the way that sparse data points were mapped. With the collection of additional data and ocean mapping using Satellite Altimetry, both of these circular features have completely disappeared. Second, the Deep Sea and Ocean Drilling projects and other marine research projects have recovered deepsea cores from the ocean floor near these alleged craters. None of these cores have found to contain a single shred of evidence, i.e. thick beds of impact ejecta, for the massive impacts proposed by Muck that should exist had they happened. Third, the effects of impacts creating 320 to 480 km (200 to 300 miles) in maximum diameter would have created tsunamis and other effects that would have, at the least, wiped out a good part of eastern North America and large parts of western Europe, which did not happen. Finally, the large magnetic and gravity anomalies that such impacts would have created are also completely lacking. There is simply a complete lack of any evidence for such large impacts where Muck claims they happened. It should be noted that the Carolina Bays all point towards the Great Lakes region not the Atlantic Ocean.

In addition, the two "parallel clefts" / "submarine cliffs" / "abysses submarines" found near Puerto Rico are now known to be an oceanic trench that are the submarine expression of the Lesser Antilles subduction zone and unrelated to any prehistoric impact. It is where oceanic crust of the North America Plate is being subducted under oceanic crust of the Caribbean Plate. Some web pages are:

When looking for impact craters, a person needs to keep in mind what stated on a "Impact Database v. 2009.2" web page at [impacts.rajmon.cz]. At that web page, it is stated:
"Do not get hung up on a single idea of an impact. Human mind
sees what it wants to see. Once you start looking for patterns
(being it circles or triangles) you will see circles and triangles
everywhere. This article illustrates the issue nicely:

(2007) What do you think this is? "Conceptual uncertainty"

Also there is "Criteria for impact crater identification - How can you tell if it is an impact crater?" at <[www.unb.ca];.
