3D map of expedition sites
This 3D image shows expedition #375 next to the Tūranganui Knoll. The Pacific plate is getting denser as it cools and nears the continental Australian plate and begins to subduct (dive under) between drilling sites U1520 and U1518. The subducting material that is not dragged under gets bulldozed up onto the hanging wall above the fault zone. This appears on the map as the purple, bluish and green ‘hillsides’ leading up to U1517.
