The USGS Shakecast Application: An Update on Shakemap’s Sibling

Description: 

ShakeCast® is a U.S. Geological Survey (USGS) software application that automatically retrieves ShakeMap shaking estimates and performs analyses using fragility functions for buildings and lifelines. As a user-focused application, ShakeCast has been developed with support from external organizations and is in close coordination with the developments in the ShakeMap application. The ShakeCast system identifies which facilities or lifeline segments are most likely impacted by an earthquake—and thus which ones should be prioritized for inspection and response—and sends notifications to responsible parties in the minutes after an event. ShakeCast can improve critical lifeline situational awareness, inspection prioritization, and reduce response times in the aftermath of a significant earthquake by focusing inspection efforts on the most damage-susceptible facilities in the severely shaken areas. Here we update the technical specifications regarding the code base, dependencies, documentation, and deployment options of the Python-based ShakeCast system and software. Engineering-based functionality improvements include our ShakeCast-AEBM (Advanced Engineering Building Module) library, the ShakeCast-HWB (highway bridge) library, the USGS Ground Failure Docker service, and integration with users’ regulatory criteria, which inform their response protocol. We further emphasize new user-centric products and automated workflows for inventory, fragility, and notifications that facilitate improved post-earthquake inspections and response protocols. Lastly, we highlight recent earthquake case histories where critical infrastructure ShakeCast users employed the ShakeMap/ShakeCast combination in their decision-making.
