Schematic Diagram of Midsection Measurement
Diagram depicting stationing in midsection measurement where velocity measurements are acquired. Each station width is multiplied by the station depth and measured velocity to compute the discharge in each section. Section discharges are tabulated to compute a total discharge for the cross section.

Southern Cascadia topography and bathymetry
Topography and bathymetry of southern Cascadia, which includes southern Oregon and northern California (seafloor depths between 200 and 3000 m are shown in the spectrum color scale from red (shallower) to purple (deeper). The land and continental shelf are shown in grayscale slope shading where darker colors represent steeper slopes.

Two models of magma storage beneath Yellowstone.
Models of magma storage. Part (A) depicts the standard model of magma storage—a single, large body of crystal-poor melt, surrounded by crystalline mush. Although this is the standard 'mush' model, geophysical studies fail to find evidence of this type of magma storage at many active systems.
