Figure F2. Map of drill site locations and peak seismic amplitude from the proto-décollement zone and décollement zone in the eastern portion of the 3-D seismic volume (DiLeonardo et al., in press). Note the northeasterly trending area of negative polarity beneath the accretionary prism. This area is interpreted as a conduit for migration of fluid from depth. Dashed lines show locations of seismic data in Figures F3 and F7. (See also Frontispiece 2.)
