Short description

This project imaged the subducted plate, upper plate, and intervening deformation in the region between the Alaska coastline and BEAAR. Here subduction passes through and past the 1964 rupture zone. The seismic array samples seismicity and images the top of the downgoing plate through and below the thrust zone. Integration with previous studies provides the longest continuous transect of a subduction zone yet available, over 700 km across strike, following a slab from the trench to coast to over 150 km depth. The array covers the largest known asperity, in the center of the great 1964 earthquake rupture.
