I have stuck two world maps together and then made a separate overlay of the plate boundaries. I have emphasized the green zero line (by hand) and drawn a black line joining the N and S geomagnetic poles and then a further black line intersecting the N-S line exactly half way. As you can see, it crosses India where the bay of Bengal is located where the poles are predicted to migrate towards. The idea of including plate boundaries is to see if volcanic and seismic activity matches magnetic activity. Click on the map in the tweet below.
