DE LA MAZA, Gabriel et al. Liquefaction-induced lateral spreading in Lo Rojas, Coronel, field study and numerical modelling. Obras y Proyectos [online]. 2015, n.17, pp.106-115. ISSN 0718-2813.  http://dx.doi.org/10.4067/S0718-28132015000100013.

The paper describes a detailed field survey conducted at Lo Rojas fishermen port in Coronel, where extensive liquefaction induced lateral-spreading was reported for the 2010, Maule earthquake. The survey includes SPT and CPT soundings, as well as the use of some surface-based geophysical techniques. The data was used to evaluate empirical prediction lateral-spread expressions and to develop a detailed hydro-mechanical finite element model. Results of both empirical expressions and numerical models agree reasonably well with post-event field observations.

Palabras clave : lateral-spreading; SPT; CPT; surface-wave based methods; empirical prediction equations; finite element modeling.
