What happened to Fennoscandia, Beringia, and Appalachia? Or, Wallace’s great Southern Continent? Or, Sundaland? Or, to Hawaiki of Maori legend? These were land masses which are no more.
Allen & Delair in ‘Cataclysm: Compelling Evidence of a Cosmic Catastrophe in 9500BC’ (1997) stated as follows:
“… crustal subsidences, sometimes amounting to vertical collapses, occurred in some regions simultaneously with the late Pleistocene elevation of mountains elsewhere. They were evidently part and parcel of the same terrible world calamity.”
“The Mid-Atlantic Ridge is also directly associated with a great world-encircling fracture complex …”
“Tachylite, a lava which naturally disintegrates in sea water within 15,000 years of eruption, lies on the sea-bed around the Azores and apparently dates from outpourings less than 13,000 years ago.”
“… may we not wonder if all these islands were once part of an Atlantic plateau extending westwards of the Anti-Atlas mountains …”
“That such possibilities should be seriously considered finds support in the discovery of geologically very young beach sand in two deep-sea cores procured in this area from depths of 10,500 feet (3,250m) and 18,440 ft (5,700m), indicating that the region was above sea level at no very remote period. Maurice Ewing concluded from this evidence that:
Either the land must have shrunk two or three miles, or the sea must have once been three miles lower than now. Either conclusion is startling. … If the sea was once two miles lower, where would all the extra water have gone?
Only the greatest conceivable disturbance could have produced crustal faults and collapses as great as these.”
“It may not be unreasonable, especially in view of confirmatory biological evidence … to regard the volcanic upheavals traced on the bed of the Atlantic around the Azores as having occurred synchronously with the breakup and subsidence of Appalachia, the name given by geologists to the continental landmass in the North Atlantic … reposing some two miles (3.2km) below the level of the adjacent continental shelves. Appalachia connected Europe and North America via Greenland and Iceland.”
