Although the seismic behavior of a hill could be considerably affected by
its geometrical shape, no comprehensive research has been reported in the literature,
clarifying the weight of this parameter. This paper compares numerically the seismic
behavior of two-dimensional semi-sinusoidal, semi-elliptical and trapezoidal shaped
hills subjected to vertically propagating incident P- and SV- waves, using the well
known 2D transient boundary element method. It is shown that although altering the
shape would not change some general observations common to all hills, but could
affect the amplification patterns along the hill significantly, depending on its shape
ratio as well as the length of the incident wave. Some approximate formula and
tables are proposed for estimating the characteristic site period and the average
amplification potential of an arbitrary shaped homogeneous single hill, which could
be applied in site effect microzonation studies of topographic areas
