Vertical uplift measured in this study plotted with inferred age and error bars. Vertical offsets across the forelimb (i.e. the amount of relative uplift between the uplifted fold crest in the hanging wall and the subsided footwall trough) were measured at the base of Units A1, A1’, A2, and B1. The range of uplift rates estimated along each seismic line incorporating the full error of the ages (based on the minimum and maximum ages of each horizon) are shown in Additional file 1: Figs. S30–S33. (a) Uplift versus age measured from Lines 1–5, 9, and 10 in this study. (b) Uplift versus age measured from the northern sections Lines 1–5. The slope of the linear regression represents the estimated uplift rate using average ages. (c)Vertical uplift measured in this study and from previous deep seismic lines plotted with average age of marine clays and bases of Units A1, A1’, A2, and B1. Uplift rate is estimated from the range of the slope of linear regression. Note the northward increase in uplift rate. Box on upper right shows data plotted from this study closed-up in a
