Turbidites in R/V Thuwal Cores 11, 12, 14, 15, 16, 17, and 18 in Aragonese and
Eilat Deeps and possibly Core 10 in the Dakar Deep - ~1970-~2000 CE (1σ)
Bektaş et al. (2024:11)
report that "
turbidites
dated to the late 20th century are unambiguously seen as
Type I events [Turbidite Event] at the tops of cores in
Aragonese and Eilat Deeps
([R/V Thuwal Cores] 11, 12, 14, 15, 16, 17, and 18) and as
Type II events [Turbidite or Flooding Event] in
Dakar Deep (Core 10)." They note that these turbidites "constitute a
perfect benchmark of our sedimentary system as they are
almost certainly the sedimentary traces of the
1995 Nuweiba (MW 7.2) earthquake,
the most recent major earthquake in the Gulf of Aqaba."
Based on
Probability Density Functions (PDFs)
presented in Fig. 8 of their paper, these turbidites
should have been deposited between ~1970 and ~2000 CE
(
1σ).
Bektaş et al. (2024:11)
further note that "given that the
Aragonese Fault,
and probably partially the
Eilat Fault
as well, were the source faults for the 1995 Nuweiba
earthquake and that the earthquake rupture propagated
northward (Baer et al., 2008; Hofstetter, 2003;
Klinger et al., 1999; Shamir et al., 2003; Ribot et al.,
2021), it is not surprising that turbidites (Type I
events) from this earthquake are not found in cores
from the southern part of the gulf (i.e., cores 1 to 10)."
Bektaş et al. (2024:11-12)
also note that "despite the proximity to the epicenter
of the 1995 earthquake, no turbidite associated with
this event is visible in core 13 due to sediment loss
at the top of that core."
