To test this possibility, we measure seismic velocities at the top of the subducted plate and compare them with predictions for hydrated mafic rocks. Regional seismic <jats:italic>P</jats:italic> waves for intraslab events at 100–150 km depth show a high‐frequency late arrival, apparently trapped in a low‐velocity waveguide 2.5–6 km thick at the top of the downgoing plate, 14.5 ± 2.2% slower than surrounding mantle. The velocities can be explained by ≥5 wt % H<jats:sub>2</jats:sub>O in the subducted crust, 2–3 times the hydration inferred for other slabs by similar methods.
