- •
We shear clay–quartz sediment in the laboratory under submarine landslide conditions.
- •
Clay-rich sediment is significantly strengthened if overconsolidation ratios are > 4.
- •
The source of strengthening from overconsolidation is cohesion.
- •
Slope failure depends on unroofing history and sediment composition.
