Re: OK Nancy, Where Is It?

Earth in Upheaval, Dropped Ocean Level, by Velikovsky

    R.A. Daly observed that in a great many places all 
    around the world there is a uniform emergence of 
    the shore line of 18 to 20 feet. In the southwest 
    Pacific, on the islands belonging to the Samoan 
    group but spread over two hundred miles, the same
    emergence is evident. Nearly halfway around the 
    world, at St. Helena in the South Atlantic, the lava
    is punctuated by dry sea caves, the floors of which 
    are covered with water-worn pebbles, now dusty 
    because untouched by the surf. The emergence 
    there is also 20 feet. At the Cape of Good Hope 
    caves and beaches also prove recent and sensibly 
    uniform emergence to the extent of about 20 feet.
    Marine terraces, indicating similar emergence, are
    found along the Atlantic coast from New York to 
    the Gulf of Mexico; for at least 1,000 miles along 
    the coast of eastern Australia; along the coasts of 
    Brazil, southwest Africa, and many islands in the
    Pacific, Atlantic, and Indian Oceans. The 
    emergence is recent as well as of the same order
    of magnitude, (20 feet). Judging from the condition
    of beaches, terraces, and caves, the emergence 
    seems to have been simultaneous on every shore. 
    In (Daly's) opinion the cause lies in the sinking of 
    the level of all seas on the globe. Alternatively, 
    Daly thinks it could have resulted from a 
    deepening of the oceans or from an increase in 
    their areas. Of special interest is the time of the 
    change. Daly estimated the sudden drop of 
    oceanic level to (have occurred) some 3,000 to
    4,000 years ago.

Q: What force, other than a total globe shaking (Richter 15 due to the
scope of the quake, as Richter includes both intensity and scope of area
affected) would cause the ocean rifts to separate so the water could
drop 16-20' worldwide?
