Abstract | A site-dependent response spectral attenuation model is an important element in a site-dependent
seismic hazard assessment. Seismic attenuation behaviour is controlled by a large number of wave
modification mechanisms, some of which have characteristics specific to a local area or a particular site, whilst
others can be generalised to the entire seismic region. Factors representing these mechanisms are often not
resolved. An attenuation modelling approach is demonstrated in this paper, to evaluate individual regional and
local wave modification factors. The upper-crust amplification factor computed from the modelled rock shear
wave velocity profile was then combined with predicted attenuation parameters to determine the upper-crust
modification filter function associated with Singaporean geological formations. Stochastic simulations of the
seismological model for the magnitude 9.3 Aceh earthquake (Indonesia) on the 26th of December in 2004,
were performed and compared with the response spectra recorded on a rock site in Singapore. |
