A seismic reflection map of the Hikurangi trench taken from JOIDES Resolution
This seismic reflection map is similar to an ultrasound and shows scientists the inside of the Earth as a cross-section. The black line at U1518 is the first drill site for expedition #375 on board JOIDES Resolution. The line shows how deep the drill went – it crosses the red fault that stretches up to the seafloor. By drilling here, scientists can pull up sediment directly from the fault zone to study.
