Correlation between Back-arc Spreading Center and Volcanic Arc Location

The dataset includes the measurements of individual subduction zones defined in the convergence-parallel, trench-perpendicular, and spreading-parallel direction. Table S3. Location of each trench, arc, and back-arc defined in the convergence-parallel direction, and the corresponding distance from the trench to the arc (D_TA), from the arc to the back-arc spreading center (D_AB), and from the trench to the back-arc spreading center (D_TB). Table S4. Location of each trench, arc, and back-arc defined in the trench-perpendicular direction, and the corresponding distance from the trench to the arc (D_TA), from the arc to the back-arc spreading center (D_AB), and from the trench to the back-arc spreading center (D_TB). Table S5. Location of each trench, arc, and back-arc defined in the spreading-parallel direction, and the corresponding distance from the trench to the arc (D_TA), from the arc to the back-arc spreading center (D_AB), and from the trench to the back-arc spreading center (D_TB).
