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 Mount Adams.

A sharp volatile-rich cap to the Yellowstone magmatic system

Seismic reflection imaging beneath the northeastern Yellowstone caldera reveals a sharp boundary at about 3.8 km depth, which is inferred to result from a mixture of supercritical fluid and magma filling the pore space.

Western US intermountain seismicity caused by changes in upper mantle flow

Results from mantle flow models reveal a relationship between seismicity away from the plate boundary in the western United States and the rate change of the vertical normal stress from mantle flow, showing that mantle flow plays an important part in shaping topography, tectonics and seismic hazard within such intraplate settings.
