Seismic evidence for a cold serpentinized mantle wedge beneath Mount St Helens

Mount St Helens is the most active volcano in the Cascades but is located 50 km west of the arc axis. Hansen et al. use high resolution seismic data to image a boundary in Moho reflectivity beneath St Helens implying a serpentinized mantle wedge and a melt source region that lies to the east towards...

Description
Summary:Mount St Helens is the most active volcano in the Cascades but is located 50 km west of the arc axis. Hansen et al. use high resolution seismic data to image a boundary in Moho reflectivity beneath St Helens implying a serpentinized mantle wedge and a melt source region that lies to the east towards Mount Adams.
