Which sediment below would have the highest cohesive strength during an earthquake?

Silty or clayey sediments typically have the highest cohesive strength during an earthquake due to their fine particle size and ability to retain water, which enhances their bonding through cohesion. Among sediments, clays, especially those with higher plasticity, can exhibit significant cohesive strength, allowing them to resist deformation. In contrast, sandy or gravelly sediments tend to have lower cohesion and may lose strength due to shaking and potential liquefaction. Thus, clay-rich sediments are generally the most cohesive during seismic events.
