Abstract
The Dead Sea Fault (DSF) is a transform plate boundary between the
Arabian plate and the Sinai sub-plate. The rate of displacement across
the fault has been estimated as 1-10 mm/yr. In this study we present
a new estimate of the current displacement across the DSF, which
is based on three years of continuous Global Positioning System measurements
(July 1996 to July 1999). Our analysis of these data shows that relative
northward velocity, which is the fault parallel component, on the
baseline between Tel Aviv and Katzerin (Golan Heights) and Katzerin
and Elat is 1.4 +- 0.3 mm/yr and -1.0 +- 0.5 mm/yr, respectively,
assuming a colored noise (white noise plus flicker noise) model for
the daily position estimates. By using a simple locked fault model,
we estimate that during the three-year observation period the relative
plate motion across the DSF was 2.6 +- 1.1 mm/yr.
