Abstract

An earthquake can inflict liquefaction hazards which can damage buildings and infrastructure. In addition, earthquakes are difficult to predict when and where earthquakes will occur and happen suddenly without being preceded by signs. Therefore, we must do a geological investigation before building construction to evaluate the potential liquefaction in that area. Evaluation of the potential liquefaction using Cone Penetration Test (CPT) is one method that can be used because repeatable, provided a continuous profile, and economically. This method needs a peak ground acceleration (amax) value at an interval of 0.1 g to 0.6 g and an earthquake magnitude of 6.2 scales Richter. Based on the results of the research was obtained in this research area, there were potential liquefactions when the peak ground acceleration (amax) value was above 0.3 g.
