Fig. 2cLoad structures were formed by liquefaction of the lower light-colored lacustrine silt that penetrated the overlaying dark clayey soil. We interpret the structure asymmetry and zigzag shapes as result of shear forces exerted on the lake bed sediments by waves sloshing back and forth Marco et al (2014) |

Fig. 3Columnar section of the sediments in a trench east of the dam. The photograph mosaic on the left shows the location of samples. Arrow shows the horizon where flame structures are observed (Fig. 2). A single 14C age of detrital charcoal from TN8 is 245 ± 30 BP. The earthquakes that were associated with tsunamis according to historical accounts are listed. The temporal constraints imposed on the observed sedimentary section and the correlation with the archeological stratigraphy indicate that the liquefaction and the damage to the dam occurred after the deposition of the laminated lake sediments and accumulation of some 30 cm of clayey soil, and before the construction of the flour mills toward the end of the Ottoman period. The earthquake of November 25, 1759 is the most plausible cause for these features Marco et al (2014) |
