• Resumen

  • Ananthaswamy examines Dan McKenzie's theory of plate tectonics. McKenzie and his colleague Bob Parker realized that the relative motion between two plates could be described by drawing a circle on the planet's surface whose axis goes through its center--an idea that dates back to an 18th-century theorem by the Swiss mathematician Leonhard Euler. This allowed the pair to calculate the relative motion of plates in the North Pacific. They found it tallied exactly with earthquake activity in the region, showing that their calculations were correct and that this movement must not only be happening but also be the likely cause of the earthquakes.
