Deformed Layer 11
Deformation Layer 11 at Nahal Darga occurs near
the top of the Holocene sequence in unit 15 and is dated and correlated by
Enzel et al. (2000) to the
1927 CE Jericho earthquake. The
deformed bed is ~0-35 cm
thick and consists of fine sand and coarse silt deposited in a near-shore fan-delta
environment. The deformed layer is described as convoluted with small
pseudo dikes.
The deformation occurred when the sediment was at
or very near the surface and the structures are
interpreted as due to earthquake-induced
liquefaction. Dating is based on
radiocarbon dating and
stratigraphic correlation within the fan-delta
sequence;
Bayesian modeling was not used in
the age determinations.
