Abstract
Seamounts are ubiquitous features of the seafloor that form part of
the fabric of oceanic crust. When a seamount enters a subduction
zone, it has a major affect on forearc morphology, the uplift history
of the island arc, and the structure of the downgoing slab. It is
not known, however, what controls whether a seamount is accreted
to the forearc or carried down into the subduction zone and recycled
into the deep mantle. Of societal interest is the role seamounts
play in geohazards, in particular, the generation of large earthquakes.
