Abstract

This paper presents a study of liquefaction potential in coastal area of Bengkulu City caused during the 8.4 Mw earthquake event on 12 September 2007. To determine the most suitable method, all methods are compared with the liquefaction event data, by fitting concept. The most suitable method was selected as the smallest error weighted factor. The suitable method is then used to determine factor of safety (FS) against liquefaction and probability of liquefaction (PL). The result shows that the suitable method in estimating the suitability of prediction and field data is Idriss-Boulanger method. In general, Liquefaction could occur at the investigated area. The critical condition of liquefaction could happen with PL of 0.495, especially medium-dense sands.
