| Abstract: | In the absence of strong motion records, ground motion during the 26th January, 2001 Kutch, India earthquake, has been estimated by analytical methods. A contour map of peak ground acceleration
(PGA) values in the near source region is provided. These results are validated by comparing them with spectral response recorder
data and field observations. It is found that very near the epicenter, PGA would have exceeded 0.6 g. A set of three aftershock
records have been used as empirical Green's functions to simulate ground acceleration time history and 5% damped response
spectrum at Bhuj City. It is found that at Bhuj, PGA would have been 0.31 g–0.37 g. It is demonstrated that source mechanism
models can be effectively used to understand spatial variability of large-scale ground movements near urban areas due to the
rupture of active faults. |
