Figure 5

Seismic profiles showing the basal shear zone (BSZ) configuration of MTC X in the (a) SMA and (b) Havsule areas. The BSZ of the MTC is characterized by its rugged topography. Here, marked topographic variations on the BSZ are caused by craters, their flanking terraces (flats), and the sidewalls that connect the craters to the terraces. All these BSZ features are notably underlain by magmatic sills in the SMA area and by polygonal faults in the Havsule area. The infill of the craters varies considerably from chaotic, low-amplitude strata (reflecting debris-flow deposits in the SMA area) to a mixture of moderate to high-amplitude strata in the Havsule area. N.B: Uninterpreted seismic profiles are provided in the appendix.
