Regional Workflow for Hazard And Loss Estimation (rWHALE)(Latest Version 1.1.0)


The extensible Application Framework presents an opportunity for community development to enhance simulation capabilities and tackle complex scientific questions in natural hazards research. Parties interested in expanding workflow capabilities should contact or join the Slack discussions linked below.

Regional Earthquake Workflow

The Regional Earthquake Workflow is for creating Scientific Workflow Applications to study the effects of earthquakes on society at the regional scale. Two instances demonstrate this framework and utilize either HPC resources at DesignSafe-CI for large-scale simulations or local computational resources for testing, development, and smaller-scale simulations. The workflow applications are seeded with ground motion tools to show extensibility and provide resources that inspire research activities. 

A testbed example provides a demonstration of the Regional Earthquake Workflow. This uses the results of a simulated magnitude 7.0 earthquake on the Hayward fault to estimate downtime & loss for every building in the San Francisco Bay Area.
