Rapid changes in field direction have also attracted significant attention, particularly in the context of polarity reversals18. Historically, the fastest directional changes were attributed to lava flows at Steens Mountain, though these results are now thought to be untenable19. Currently, the fastest directional changes noted are those recorded by sediments in central Italy20, where angular changes in the Virtual Geomagnetic Pole position (P^V) reach values of ∂P^V/∂t∼1∘yr−1. These rates are about a factor of 10 faster than values of ∂P^V/∂t∼0.1∘yr−1 for the modern field, similar to the difference in rates of intensity change between the modern field and spikes.
