7. Release Notes

7.1. Version 4.1.0 (Current)

Release date: March 2024


  1. Upgrade the earthquake event generation toolbox to support simulation of Peak Ground Velocity (PGV) and liquefaction induced Permanent Ground Deformation (PGD).

  2. Enhancements to the BRAILS-Buildings widget, providing detailed user interaction with the existing BRAILS building inventory generation capabilities. In brief, these enhancements enable:

    1. Importing footprint and building data from i) OpenStreetMaps, ii) Microsoft Global Building Footprints dataset, iii) FEMA USA Structures, and iv) user-specified data sources.

    2. Using National Structures Inventory data or other user-specified data to create a baseline building inventory.

    3. Requesting a subset of BRAILS attributes for inventory generation.

  3. Update the damage and loss engine Pelicun to v3.3.

7.2. Version 4.0.1

Release date: Jan. 2024


  1. Support the assessment of transportation infrastructure.

  2. Revised interface for earthquake scenario simulation tool.

  3. Added Brails-Transportation tool to generate transportation infrastructure inventory.

  4. Allow using PreTrained Surrogate Models from EE-UQ as structural analysis models.

7.3. Version 3.0.0

Release date: May. 2023


  1. Revised Interface, added new Tools section and moved some existing applications to that pulldown

7.6. Version 2.0.0

Release date: Dec. 2021

  1. QGIS integrated into R2D with the ability to:

    1. load several types of GIS files into R2D to visualize and extract information post-process results based on advanced queries and expression filters join external databases to GIS features to add additional information for pre- and post-processing export GIS layers into many supported formats for viewing in other GIS applications

  2. Filtering of assets to include in an analysis based on advanced queries and expressions

  3. OpenQuake source selection tool

    1. OpenQuake Scenario-Based Seismic Hazard Analysis to calculate intensity measure from OpenQuake rupture sources

    2. OpenQuake Classical Probabilistic Seismic Hazard Analysis to calculate intensity measures from OpenQuake seismic source and ground motion logic trees

  4. Widget to import building inventory in ShapeFile format

version updates to 2.0.0 as older versions run at design-safe will not load due to changes in backend.
