Fig. 6

Separation of the double seismic zone plotted against the age of the subducting slab. Distances between the upper and lower seismic planes are shown by three different symbols: triangles show typical down-dip compression overlying down-dip extension, circles indicate a different pattern, and crosses denote unknown. Vertical lines attached to the symbols are one-standard deviation uncertainties from Gaussian fits. Predicted separations of the double seismic zones based on the lower seismic planes resulting from the dehydration of antigorite and chlorite based on Hacker et al. (2003) are shown as blue and green shaded areas, respectively. (After Brudzinski et al. 2007)
