Tremors caused by distant Sumatra earthquakes have reportedly been felt in Singapore for many years. Based on a previous study (Megawati and Pan, 2002), the maximum credible earthquakes (MCEs) from Sumatra are hypothesized to be a subduction earthquake (Mw = 9.0) and a strike-slip earthquake (Mw = 7.5). Response at a soft soil site to the synthetic bedrock motions corresponding to these maximum credible earthquakes are simulated using a one-dimensional equivalent-linear technique. It is estimated that such maximum credible earthquakes are able to induce spectral acceleration levels exceeding the threshold provided for by the existing building codes for a wide frequency range, thus demonstrating their inherent potential for damage to building structures.
