USGS geophysicist Jared Kluesner points at a three-dimensional cross-section of seismic data about 40 kilometers across and several kilometers deep located in the Santa Barbara Channel. This imaging deep below the seafloor allows scientists to visualize and map faults better.

Jared Kluesner displays a 3D view of seismic data collected off Santa Barbara. This visualization helps him analyze the Earth’s layers from the seafloor (rainbow-colored surface) to several kilometers below (slices extending down from the colored surface).
