Abstract : The geometry of the division of the earth's surface by the major tectonic plates is remarkably regular and symmetric, and several models based on the platonic solids have been proposed to describe this pattern. Under such a model, the triple points, those points at the boundary of three plates, will have an exceptionally regular distribution. We have tested the distribution of the major triple points using a Monte Carlo computational approach and found it to depart significantly from random, independent and uniform placement of points. Given the natural human tendency to see patterns in situations where, in reality, only unstructured randomness actually exists, the formal testing of hypotheses helps to conform the validity of these structural geologic models.
