Key Points:

We interpret micro-faults, soft-sediment deformation, slumps, and detachment surfaces as paleoearthquake/tectonic indicators

The core records five seismite clusters between 3.6 and 2.7 Ma, revealing episodic thrusting in relation to intense regional deformation

During the clusters, regional deformation was concentrated more in the fold-and-thrust system than along regional major strike-slip faults
