"Rectified Diffusion" (Sturtevant-Bradford et al. 1996; Brodsky et al. 1998) is a mechanism that has recently been hypothesized to be the trigger in seismically-induced volcanic eruptions. We argue that Rectified Diffusion ought to have a specific observable signature on the compressional-wave attenuation of the magma chamber. Measurements of seismic attenuation potentially provide a means of testing whether Rectified Diffusion is occuring in a particular magma chamber, and thus may provide a way of monitoring its eruptive potential. It may also provide a means of mionttoring changes in the concentration of volatile bubbles in the magma chamber, even when the Rectified Diffusion effect is not large enough to permit triggered eruptions. We request funds to develop the underlying theory that links Rectified Diffusion to seismic attenuation, and use it to design practical measurement strategies that can be applied to existing seismic data and future montoring efforts.
