Visualization of Subduction Slabs


These figures show how the three-dimensional shape of subduction slabs is constrained by the location of deep earthquakes.  Earthquake locations are drawn from the Engdahl data set.  Color indicates how well-located the earthquakes at that point are (dark blue is best located; red is worst located).  Click on links to see more images.
