3а. Seismоlоgy The diаgrаms belоw show cross sectional views of seismic tomographic images obtained at three different subduction zones (cross-sectional lines at the top of the tomographic images [for example A-A’] relate to the locations in the underlying geography map). Answer the questions located below the location map. (a) [2pts] The dashed lines in the tomographic images highlight the edges of subducting oceanic plates (shown in Blue). What properties of the ocean lithosphere might lead seismologists to interpret these blue regions in the asthenosphere as subducting plates. (b) [3pts] Along the A-A’, B-B’, and D-D’ lines, which directions (N, S, W, E, NE, NW, SE, or SW) are the subducting plates dipping. Write the correct dip direction for A-A', B-B' and C'C'.
