Paleomagnetic data from latest Miocene to Pliocene sedimentary rocks in southeast Kyushu, as well as those previously reported from middle to late Miocene formations, show that a large part of south Kyushu has been rotated approximately 30 degrees counterclockwise with respect to north Kyushu and Eurasia during the past 2 m.y. This rotation started synchronously with rifting of the continental crust beneath south Kyushu and the northern Okinawa trough, which commenced around the Pliocene-Pleistocene boundary and continues to the present. The coincidence of rotation and extension implies that arc rotation can take place during rifting of continental crust.
