Fig. 3From: Three-dimensional mapping and kinematic characterization of mass transport deposits along the outer Kumano Basin and Nankai accretionary wedge, southwest JapanFrontally confined versus frontally emergent MTDs. Black arrows indicate primary translation direction. Purple arrows indicate onlapping relationships. BSS—basal shear surface. a Frontally confined landslide. The arbitrary seismic line across MTD 4 (see Fig. 6 for location). Note how the landslide mass is buttressed against undisturbed strata. b Frontally emergent landslide. Seismic Inline 2352 across MTD 6 (see Fig. 7 for location). Note the runout of the landslide mass beyond the frontal rampBack to article page
