El Ouahabi et al. (2018) identify a minor sedimentary event at ~205 cm depth, below the main E2 interval. This layer shows minor structural disturbance associated with sand, and is part of a broader set of anomalous deposits marked by coarse particles, elevated magnetic susceptibility, reworked material, and structural deformation within the Amik Lake sequence (El Ouahabi et al., 2018:5).

The evidence for an earthquake is weaker than for E2. Unlike the main E2 deposit, the 205 cm layer is not described as containing clear sand dikes or well-developed micro-sand pockets. It is therefore best treated as a possible earthquake-triggered deposit rather than a secure event horizon. Its interpretation is strengthened, however, by its position in the Amik basin, close to the Hacipasa Fault segment, where seismic shaking could disturb saturated lake and marsh sediments.

Chronologically, the 205 cm event is constrained by the authors' age–depth model, which combines radiocarbon dating of micro-charcoal, sedimentation-rate estimates, environmental markers, and historical earthquake tie points. The 205 cm anomaly lies within unit 3, falls within the Ottoman/Islamic period framework established by the authors’ age–depth model, and dates to ~750 CE.
