Structure and Fate of Subducting Slabs

Authors


Abstract

Yesterday Larry, a colleague, rushed desperately into my office asking whether the subducting lithospheric slab in Vanuatu is continuous from the surface down to 600 km depth. For some reason I have the reputation of knowing such things, and even I suppose that I should know them. The truth is, I can never remember, so what do I do? I look in Lay's book on subducting slabs to find a discussion and references detailing the search for high-frequency signals traveling upslab in Vanuatu and elsewhere. A becalmed Larry leaves my office; for now, my reputation is safe.
