This poster discusses several possible approaches by which the nonlinear response of surficial soils can be explicitly modelled in physics-based ground motion simulations, focusing on the relative advantages and limitations of the various methodologies. These methods include fully-coupled 3D simulation models that directly allow soil nonlinearity in surficial soils, the domain reduction method for decomposing the physical domain into multiple subdomains for separate simulation, conventional site response analysis uncoupled from the simulations, and finally, the use of simple empirically based site amplification factors We provide the methodology for an ongoing study to explicitly incorporate soil nonlinearity into hybrid broadband simulations of the 2010-2011 Canterbury, New Zealand earthquakes.

A sign on a tent set up in the Arts car park at the University of Canterbury after the 22 February 2011 earthquake. The tents were used as temporary lecture rooms while the buildings were being checked for damage. The sign reads, "Clyde 4, ANTH 102 in E338 Drawing Room Mon 11Am, 155 Seat".
