Japan's risk of giant tsunamis may have grown when the angle of a down-going slab of ocean crust declined. Top: ocean crust (right) slides under continental crust at a steep angle, causing faulting (red lines) in seafloor sediments piled up behind. Bottom: as the angle shallows, stress is transferred to sediments piled onto the continental crust, and faults develop there. Blue dots indicate resulting earthquakes. At left in both images, the change in angle also shifts the region where magma fueling volcanoes is generated, pushing eruptions further inland.

The SHIRE project, which contributed resources to this research, is investigating seamounts within the Hikurangi Trench, to learn how they generate or dampen earthquakes at different stages of subduction. This seismic image shows a seamount known as Puke Seamount, colliding with New Zealand. Image: SHIRE/Andrew Gase.
