Amasia is a possible future supercontinent that could be formed by the merger of Asia and North America and is an alternative to Pangaea Ultima. This relies mostly on the fact that the Pacific Plate is already subducting under Eurasia and the Americas, a process which if continued will eventually cause it to close. Meanwhile, because of the Atlantic Ocean mid-ocean ridge, North America would be pushed westward. Thus, the Atlantic at some point in the future would be larger than the Pacific. In Siberia, the boundary between the Eurasian Plate and North American Plates has been stationary for millions of years. The combination of these factors would cause North America to be combined with Asia, thus forming a supercontinent.
Roy Livermore, now at the University of Cambridge, in the late 1990s created Novopangea, assuming closure of the Pacific, docking of Australia with eastern Asia, and northward motion of Antarctica. Amasia, Novopangea and Pangea Proxima are discussed in the book 'Supercontinent' by Ted Nield, and illustrated in Pangaea, the comeback in the New Scientist magazine issued 20 October 2007.
Novopangea was shown in the series of The Future Is Wild.
