NCSA and the Mid-America Earthquake Center developed MAEviz, now Ergo, to provide detailed predictions of the damage resulting from an earthquake, including the toll on people, infrastructure, and services. With Ergo, “what if” models and risk-reduction strategies can be evaluated by both researchers and decision makers in an effort to avoid a catastrophic impact on society in the event of an earthquake. Ergo integrates the latest research findings, most accurate data, and new methodologies into a single software product.


Ergo, previously MAEviz, is an open-source project that helps reduce the time from discovery gap that exists between researchers, practitioners, and decision makers by integrating the latest research findings, most accurate data, and new methodologies into a single software product. Ergo is a joint effort between the Mid-America Earthquake (MAE) Center and the National Center for Supercomputing Applications (NCSA) to develop the next generation of seismic risk assessment software. Ergo is leveraging off NCSA’s cyberenvironment efforts and the University of Michigan’s Sakai collaboratory to provide an advanced framework for earthquake engineering, as well as general hazard and risk research, harnessing multi-institutional expertise, as well as existing and new tools across a broad range of technologies. The open-source framework of Ergo employs the latest and most advanced workflow tools to provide a flexible and modular conduit through which the culmination of the interdisciplinary research and development efforts of the MAE Center are integrated and delivered to end-users. Ergo follows the Consequence-based Risk Management methodology (as shown at the bottom of this page) using a visually-based, menu-driven system to generate damage estimates from scientific and engineering principles and data, test multiple mitigation strategies, and support modeling efforts to estimate higher level impacts of earthquake hazards, such as impacts on transportation networks, social, or economic systems. It enables policy-makers and decision-makers to ultimately develop risk reduction strategies and implement mitigation actions.

MAEviz (now Ergo) was reviewed by the Global Facility for Disaster Reduction and Recovery in their Review of Open Source and Open Access Software Packages Available to Quantify Risk from Natural Hazards, page 20.
