Seismic Arrays in Fiji and Tonga (SAFT)

SAFT was a one-year deployment of 27 seismometers on the islands of Fiji and Tonga. These two arrays will allow for detailed study of the Tonga subduction zone and deep earthquakes. The Fiji array will help constrain mineral properties and phase changes in the down-going slab by looking at mantle discontinuities, and the Tonga array will be used to study the structure of the subducting crust.
