== Alternative scenarios == Paleogeologist Ronald Blakey has described the next 15 to 100 million years of tectonic development as fairly settled and predictable but no supercontinent will form in that time frame. Beyond that, he cautions that the geologic record is full of unexpected shifts in tectonic activity that make further projections "very, very speculative". In addition to Novopangaea, two other hypothetical supercontinents—"Amasia" and Christopher Scotese's "Pangaea Ultima"—were illustrated in an October 2007 New Scientist article. Another supercontinent prediction, Aurica, has been proposed in more recent times, suggesting the closures of both the Atlantic and Pacific Oceans.
