Detailed imaging of Mount Rainier (red triangle) shows subduction zone in glorious detail | Ars Technica  - Seismic+EM section across Cascadia subduction zone: sea water driven off slab, magma rising up.  The colors represent electrical resistivity, with red being low. Contour lines show temperature in degrees Celsius. Small red circles show the centers of earthquakes.
