Abstract
The results of several seismic reflection surveys in the Jericho area,
north of the Dead Sea, are described and the data are used to analyze
the structure of this part of the Dead Sea Rift. In particular, we
describe the structure of the Dead Sea Transform, which in this area
is a zone of intense deformation, rather than a distinct fault plane.
The transform has a westerly dip, away from the rift, suggesting
that it may have a reverse-faulting component. Associated with the
transform are several folds, of which the best documented is the
Kalia Monocline, immediately north of the Dead Sea. The Kalia Monocline
lies along the transform and appears to be a young structure associated
with it, indicating that this part of the plate boundary is characterized
by local compression. The southerly extent of the Kalia Monocline
is not clear presently, but the available data suggest that the compressional
field also characterize the northwestern part of the Dead Sea Basin.
The other folds appear north of the Kalia Monocline and seem to be
similar to it. They are, most probably, also the result of recent
compression along the transform. A number of mechanisms of small
earthquakes in this area are computed and several of them show thrusting,
suggesting that the local compression is still active.
