| Abstract | ||||
| Composite focal mechanism solutions are examined for five groups of earthquakes which took place in the Gulf of Suez and recorded by Hurghada seismic network during the period from 1994 to 1995 to investigate the trade off the type of the focal mechanism solution and the evidence of the tectonics for the area. The composite solution in the first group area is dominated by reverse fault with pressure axis S-E to N-W, while a normal fault solution in the second group area east of the first group with tension axis of NE- SW is observed.The solution is consistent with tension axis due to the opening Red sea The third and the fourth groups are characterized by reverse fault with strike slip component (diagonal fault ). The fifth group is characterized by a normal fault with tension axis of NW- SE, which is consistent with tension axis extended in the Gulf of Suez due to the opening of the Red Sea. The Moment Tensor components are calculated from the fault plane parameters (strike (φ), dip (δ) and rake (λ)) for each group | ||||
