Abstract

At 29/10/1989, Tipaza’s region situate in the west of Algiers, was vibrate below a Chenoua earthquakes. A distance between the centre of this earthquakes and Algiers the capital, wasn’t a to make a damages for the constructions (Casbah, Bab El Oued, Hamma, Tagara...). Because this one is dating for the colonial era, and haven’t a para-seismic structures. Then determination of zonal effects is one of the essential components of para-seismic prevention, having recourse to macro-zoning. The conventional method of measuring zonal effects experimentally is based on seismic recording. It is admittedly reliable, but it is laborious We suggest in this paper an original method evaluated, here consists of recording a few minutes of seismic background noise on a site and establishing the spectral ration of the horizontal path to the vertical one. It is thus an economical method of mapping resonant frequencies and thereby gaining a better knowledge of seismic risk in sedimentation basins.

Evaluating the Response of Soils to Seismic Tremors by Recording Background Noise
