Magnetic studies of the GFZ German Research Centre for Geosciences on sediment cores from the Black Sea show that during this period, during the last ice age, a compass at the Black Sea would have pointed to the south instead of north." http://www.sciencedaily.com/releases/2012/10/121016084936.htm Link to comment Share on other sites More sharing options...
Taun Posted October 18, 2012 #2 Share Posted October 18, 2012 I wonder is they will ever figure out what caused it... And if it and the super volcano happening so close together was a coincidence or a consequence... Link to comment Share on other sites More sharing options...
Ashotep Posted October 22, 2012 #3 Share Posted October 22, 2012 I wonder if we are getting ready for another polarity reversal and if there will be another super volcano eruption when it does. Link to comment Share on other sites More sharing options...
Insignia Posted October 24, 2012 #4 Share Posted October 24, 2012 "The actual polarity changes lasted only 250 years" It LASTED for 250 years but it gives no indication of how long the "rapid" changing actually took. How long did it take for the poles to reverse? Link to comment Share on other sites More sharing options...
