| The tensional stresses in the uplift can be relaxed by, for example, underthrusting in a subduction zone, or contraction in surrounding regions. |
| The subduction zone beneath northeast Honshu is marked at the surface by the Japan deep-sea trench and associated island arc. |
| Schematic block diagram showing major features of a subduction zone and spreading ridge, such as are found in southwestern British Columbia. |
| Increasing proximity to a subduction zone during plate convergence is indicated by the appearance of felsic tuff. |
| The most conspicuous outboard structure is the accretionary wedge that lies just continentward of the ocean trench, the bathymetric manifestation of the subduction zone. |
| Like all earthquakes, great subduction zone events are complex when considered in detail. |
