Abstract
This paper shows a new methodology of real-time prediction of liquefaction. The methodology is focused on the frequency characteristics at the liquefied ground. In practical approach, Arias Intensity, which is calculated from the observed strong ground motion records at ground surface and the soil properties of the observed point are used. By categorizing the liquefied site and the non-liquefied one of past earthquakes by soil properties and calculating Arias Intensity in every moment after occurrence of earthquake, the methodology can be applied in the real-time prediction of liquefaction. The accuracy of the proposed methodology is verified by the scenario earthquake. It is shown that the results have adequate accuracy.
