Comparison of the MCS profiles (depth section) perpendicular and parallel to the Yaeyama Rift. Left: Across-rift line ECr5. Vp model around the rift is also shown. Right: MCS depth profiles for rift-parallel lines of ECr13, ECr12, and ECr3. Noticeable volcanic intrusions are shown by up-arrows. Smaller arrows indicate small-scale intrusions. More and larger intrusions were detected along ECr13 compared with ECr3, indicating an asymmetric seismic structure across the rift axis
