Charge: The SEIR working group is currently focused on two main goals: (1) Encouraging and supporting use of R2D as it currently exists; and (2) Identifying, prioritizing, and beginning to implement the next models and data to be linked or added to R2D. Towards these aims, we are actively soliciting input from a wide range of social scientists and engineers who may use R2D and/or contribute models or data in the future about how R2D can best serve their research and education needs.

Developer Liaison: Jinyan Zhao (UC Berkeley)

Charge: This task group is focused on guiding the development and research applications of software to simulate the effects of earthquakes on buildings, transportation and utility systems, and communities. The scope includes (1) developing data models and API’s to integrate earthquake hazard software and data (e.g., OpenSHA, OpenQuake, physics-based simulations) in SimCenter workflows, (2) coordinate with other SimCenter working groups on common issues concerning inventories, socio-economic effects, and UQ developments, (3) develop a data integration framework for multi-fidelity models (geotechnical, structural, socio-economic, civil infrastructure systems) into high-resolution regional simulations, and (4) develop and promote activities to engage the research and education communities in earthquake engineering, risk and recovery. The working group supports development of the following SimCenter tools: PBE/pelicun, R2D/rwhale, EE-UQ, and quoFEM.

Affiliated SimCenter Personnel: Andrew Kennedy (Notre Dame), Michael Motley (Univ of Washington), Patrick Lynett (USC)
Developer Liaison: Abiy Melaku (UC Berkeley)
Other Working Group Members: Mohammad Alam (Notre Dame)

Charge:

• Guide development and application efforts for regional hurricane and tsunami simulations
• Develop data models and tools to integrate SimCenter tools with wind, storm surge, and tsunami hazard tools (ADCIRC, GeoClaw)
• Coordinate with other working groups on common inventory, socio-economic, and UQ developments
• Expand hurricane and tsunamic damage and consequence simulation tools for building, transportation and utility infrastructure components and systems
• Develop/integrate data framework for multi-resolution damage models (empirical vs component-based)
• User engagement, education and outreach

Current Priorities: The initial scaffolding of the regional simulation workflow for hurricanes culminated in two testbeds (Lake Charles, LA and Atlantic County, NJ) with particular emphasis on the treatment of wind hazards. Thus the working group is currently focused on:

• Developing greater capabilities to simulate coastal hazards and their impact on the built environment, encompassing both hurricane storm surge/wave action and tsunamis
• Conducting an ongoing community needs assessment to inform development priorities
• Based on initial needs assessment, developing a slate of utility applications that will provide immediate benefits as standalone applications addressing common pain points in computational simulation for coastal hazards, while contributing a core building block for a fully orchestrated regional simulation workflow for coastal hazards.

Charge: The Uncertainty Quantification (UQ) working group facilitates the integration of computational statistics tools to address uncertainty characterization and propagation in natural hazards engineering problems. Developments coming out of the working group permeate across all SimCenter products for which uncertainty plays an important role. Topics of emphasis include the efficient uncertainty propagation for performance based engineering and regional loss assessment applications, and the Bayesian formulation of model calibration problems.
