Research in earthquake engineering is focused on creating new methods and technology to improve performance of the built environment in earthquakes. We motivate this talk with an example of current simulations of seismic behavior of a Soil-Structure Interaction (SSI) system. More specifically, the analysis is concerned with the safety of the new bridge structure. For this analysis, a number of computational and visualization issues had to be tackled. The work will be presented in light of both Neumann (physical) and Turing (computer) computability. In particular we will present computational methods related to:

- Simulations of boundary conditions for the SSI system (earthquake input motions),

- Distributed parallel simulations of the SSI system,

- Data visualization of large tensorial data sets resulting from the SSI system simulations.

In addition, an emerging Earthquake Engineering Grid Computational Platform will be discussed.
