...Lowering of surface elevations relative to water tables (van Ballegooy et al., 2014a, 2014b, 2014c) is also likely to have increased the liquefaction and flood hazard....

...Liquefaction damage indices, such as LSN [22] and LPI [14,15] use specific weighting functions to quantify the damage potential of liquefying layers depending on their proximity to the ground surface, but still they do not account for cross-interactions between different layers during the development of liquefaction and post-liquefaction triggering....

...It is evident from this figure that out of the 34 cases for the NN-sites (17 sites for two events), both LSN and LPI correctly predicted no occurrence or minor liquefaction for only 3 cases (9% of the cases), whereas for 31 cases (91% of the cases) liquefaction manifestation was heavily overestimated....
