  • ‘g’ = granule (2-4mm)
  • ‘p’ = pebble (4-64mm)
  • ‘c’ = cobble (64-256mm).

Granulometry particle size distribution completed using Ocean Data View version 4.3.10. Correlation between the anomalous horizons of both cores presented. Detail of foraminifer counts and radiocarbon ages available in data repository. Examples of color ranges and corrasion of foraminifera in anomalous horizon as presented in Amphistegina lobifera (d’Orbigny 1826).

Goodman Tchernov et al (2016) identified a paleo tsunami deposit close to Elat from two submarine cores taken at North Beach and Tur Yam locations. They described the dating as follows:
The radiocarbon age from the North Beach places the maximum age at 100–400 BC (2 sigma error), while the Tur Yam radiocarbon age brackets the horizon as a minimum age of 100–500 BC (2 sigma error). Highest probability of these two radiocarbon ages place the event at about 2300 yBP, or around 200–300 BC (Data Repository).
The tsunamite deposit in the Tur Yam core was inferred from "an anomalous bed (~60cm) of more concentrated mixed shell and broken coral fragments of varying condition from pristine to heavily worn and eroded." The inferred tsunamite deposit in the North Beach core was encountered "at a depth of 160 cm down-core [where] the grain size increases to greater than coarse sand (>250 micron) and foraminifer abundances decrease significantly to either low or barren (0–150 individuals per cm3)." The anomalous bed in the North Beach Core was ~32 cm. thick.

Beverly Goodman-Tchernov (personal communication, 3 Jan. 2023) reports that a weak tsunami signature from the 1068 CE Quakes(s) may be present in sediments in the cores taken in the vicinity of Elat.
