Abstract

Strong-motion parameters, peak ground acceleration, peak ground velocity, and peak ground displacement depend on several factors, such as the source of earthquake, distance between the source and site, and the characteristics of that site. Five seismographs and two accelographs were installed by the Egyptian Geological Survey team along the western side of the Gulf of Aqaba from Taba to Sharm El-Sheikh to record seismic events during the period from September 1995 to June 1996. During this period, two events were recorded by the accelographs. The two accelographs were located on the surface of the basement rocks, the first near the epicenter and the second at a farther distance. However, the farthest accelograph recorded higher values compared to the nearer one. Fault mechanics are an important factor in determining the values of strong motion parameters, where the direction of the rupture line plays an important role in detecting the values of strong motion parameters, the strong motion parameters and damage effects seem to be attenuated very fast in the direction perpendicular to the rupture line. This can be interpreted by the fact that the farthest accelograph lies at the extension of the fault rupture (azimuth = 30°), while the nearer one was perpendicular to the strike of the fault rupture.

Keywords Rupture line - Strong-motion parameters - Fault mechanics
