Instrument Request for Mount St Helens aka iMUSH (201406)

Name: Mount St Helens aka iMUSH

Long Name: Collaborative Research: Illuminating the architecture of the greater Mount St. Helens magmatic systems from slab to surface


A 70-element broadband array will be deployed for two years, in a 50-km-radius pattern surrounding the Mount St. Helens volcano. This array will be used for a variety of analyses, both of Earth structureand seismicity. The 10-15 km station spacing is designed to optimize imaging from the middle crust to slab, and to provide a substantial boost in our ability to detect small earthquakes and deep long-period earthquakes. P- and S-wave tomography using both earthquake and active sources will be applied to direct and Moho-reflected arrivals to image the volcano. Receiver functions analysis will reveal wavespeed discontinuities in the mid crust, Moho and subducting slab. Ambient Noise Tomography will provide constraints on the shear wavespeeds throughout the crust and upper most mantle.
