ShakeMap: An Update

Description: 

The U.S. Geological Survey’s (USGS) ShakeMap product has become a major source of post-earthquake information to emergency response and planning organizations, as well as for public awareness. The ShakeMap software has been adopted by dozens of regional and international seismic organizations as their principal tool for communicating earthquake effects. ShakeMap also provides the necessary inputs to several important “downstream” products, such as PAGER and USGS Ground Failure. ShakeMap is under continuous development, and in this presentation we will discuss several new features, which include: 1) Adoption of the Engler et al. (2022) approach to separating within- and between-event uncertainties in the ShakeMap output (ShakeMap v4.1), which facilitates spatially-correlated realizations of ShakeMap outputs; 2) A new installation procedure that eliminates many of the earlier dependency conflicts; 3) Major progress on moving ShakeMap to the cloud (specifically Amazon Web Services); 4) Development of tools to visualize network response to (scenario) earthquakes with finite faults; 5) Many other system enhancements and upgrades to support the latest versions of OpenQuake Ground Motion Models, Python 3.9, MacOS X, etc.; and 6) Moving the ShakeMap repository to GitHub Enterprise.
