| Popis: | Volcanic ash deposits have been proposed to potentially liquefy and act as preferential failure planes during submarine landslides along active margins. However, particle angularity and surface roughness of volcanic material significantly influence its shear behavior and hence do not unambiguously support this contention. This manuscript challenges the hypothesis of preferential failure of ash layers by conducting drained and undrained monotonic and undrained cyclic triaxial shear experiments (σ’n |
