Figure 2. Top panel shows JASON short-probe heat flow data over the Deformation Front and First Anticlinal Ridge shown in Figure 1. Red bars show locations of reduced heat flow areas hypothesized to be areas of fluid inflow into the upper sediment layers. Lower LANGSETH seismic profile is co-registered with the heat flow stations and shows the Juan de Fuca plate entering the CSZ from the right and the deformation front and First Anticlinal Ridge. The x-axis is MCS Common Depth Point where 400 CDPs represents 2700 meters.
