  • Dating submarine slides is important for two main reasons: 1) relating a particular deposit to a specific trigger event (e.g., earthquake, volcanic eruption or a tsunami wave) for which we have instrumental or historical documentation, or 2) define the recurrence of slope failures by assigning the age to multiple stacked mass- transport deposits in a basin, thereby improving our ability to assess geological hazard. Improved age assessments of mass-transport deposit may also result in a better understanding of their relation to key environmental parameters such as sea level and supply fluctuations driven by climate change. This contribution discusses 4 cases in which dating the failure deposit proved problematic: a slide deposit with a stratified accumulation zone, a slump mass with undisturbed stratigraphy above relatively-deep rotational plane, an extensive blocky slide deposit exposed upslope but buried in its distal accumulation zone, and a collapsed area showing a well defined head scarp but no accumulation zone.
