Fig. 12. Seismic map of Syria, showing the five seismic zones, and distribution of the
earthquakes which their magnitude more than 4; white square: M> 6 ; black circle: 5< M < 6;
black square: M< 5 ;white; circle: M=4,9 - 4(A), and odometric result where the black part
indicate the relative damage(B).
According to the movement rate, estimated in the field between <1mm/yr and 2, 7 -3, 3
mm/yr, the Z value estimated at 0-0.25 cm/S2, the relative seismic intensity measured in
laboratory (Bilal and Mahmoud 1997), the analysis of recent seismicity documented by the
seismic network, and finally historical record, we have identified a number of seismic zones
and corresponding seismic intensity (Tab.2).
These zones are represented on a seismic map of Syria (Fig.12A), established here for the
first time. This map divides Syria into five zones, each of which corresponds to a given
seismic intensity value. Zone one has the highest seismic intensity risk, with most potential
damage for the constructions, while zone five has the lowest one.
On the same figure (12A) , the earthquake epicenters with a magnitude higher than 4 are
projected. They occur in the whole territory but mostly in zones 1 and 2, associated with
volcanism, or along the Damascus-Palmyra mountain chain. Only some earthquakes had a
