Assessment of dike stability under earthquakes induced by gas extraction

Probabilistic assessment of structural damage from coupled multi-hazards

“…The connection between the earthquake and the flood is thus related to the strength of the levee. The critical PGA for levee failure was characterised with a single PGA value which was assigned a lognormal probability distribution loosely based on the study of Zuada et al [28] on levee capacity of similar canal levees (see Fig. 11); from this study, only a few values were ported to produce the probabilistic distribution shown in Fig.…”

“…The usage of a single-parameter distribution to relate the occurrence on the flood to the earthquake was deemed sufficient to illustrate the methodology. The study performed by Zuada et al [28], for example, evaluates levee strength due to multiple failure mechanisms which depend on various properties of the levee. Such variations, and other variations of the first hazard (frequency content or principal direction for the case of an earthquake) and their consequence on the properties of the second hazard (type of levee breach, for example), can be (but have not been) included.…”
