000019532 520__ $$2eng$$aRecent megathrust events in Chile have provided the engineering community, with case studies that allow the evaluation of current state of practice, regarding liquefaction triggering analysis. This evaluation is performed in the context of long duration and high frequency content ground motions. Field observations show an apparent mismatch between observed and predicted liquefaction behavior during the 2010 Mw 8.8 Maule and the recent 2015 Illapel Mw 8.3 earthquakes. We speculate on the reasons for these differences. Partial drainage during the strong shaking could lead to a frequency dependence of the liquefaction behavior, we concur with studies that suggest that soil stiffness (i.e. shear-wave velocity or site period) are relevant parameters to be included. Also the results show that for the case of megathrust events, PGA is not the best-suited intensity parameter to proxy earthquake demand. We conclude that more research is needed in this relevant issue.
