Cores from New Zealand's Hikurangi Subduction Zone

Caption

The UTIG-led expedition drilled cores from the subduction zone and revealed a surprising diversity in the rocks buried half a mile beneath the seafloor. This mash-up of rocks means a mix of weak and strong points in the Earth's crust which the scientists say influences the occurrence of earthquakes.
