MASTODON: Multi Hazard Analysis for Stochastic Time-Domain Phenomena

MASTODON is an open source, seismic analysis and risk assessment tool under development at the Facility Research Group (FRG) at Idaho National Laboratory (INL). MASTODON’s capabilities include earthquake fault-rupture simulation, source-to-site wave propagation using the domain reduction method (DRM), nonlinear soil-structure interaction analysis (NLSSI), simulation of seismic isolation, fluid-structure interaction analysis, probabilistic seismic risk assessment including fault-tree quantification, and design optimization of safety systems for risk and cost. MASTODON has both implicit and explicit integration capabilities and can be used for a range of applications, from buildings and bridges to safety-critical infrastructures such as dams and nuclear power plants. MASTODON is hosted on GitHub and being developed with rigorous quality assurance to eventually meet NQA-1 standards.

This session provides an overview of MASTODON and demonstrations of the capabilities of the software. Demonstrations include nonlinear site-response and soil-structure interaction analysis, seismic isolation, and seismic probabilistic risk assessment. The session also provides information on software development, code contribution process, and quality assurance in MASTODON.
