ABSTRACT: The present study aims mainly at investigating the site effect at the new Luxor city, Egypt, using
microtremor measurements. Accordingly, 41 ambient noise recordings were implemented covering the investigated area in
a reasonable manner with spacing nearly 1 km between each measurement station.
The data were analyzed using Nakamura’s technique. The results show that; the investigated
area exhibits low fundamental frequency values ranging between 0.28 - 0.47 Hz
and its corresponding amplification factor values vary between 2.3 and 6.8. Consequently, the studied site
is characterized by the presence of thick soft sediments overlying a hard bed
rock. The seismic vulnerability index (Kg)
was estimated, relying on the estimated fundamental frequency (F0) and amplification factor
(A0), through the range
between 11 and 95 across the mapped area. The obtained Kg values were noticed to be compatible with amplification level
results. The central part of the investigated area reflects the higher Kg and A0 values.
