The newly released OpenQuake Engine 3.25 introduces significant improvements in performance and workflow optimization for large-scale seismic hazard and risk analyses. The updated version has been optimized to operate more efficiently, particularly when processing large computational models and datasets.
With this release, system performance has been improved, memory consumption has been reduced, and the overall computational workflow has been enhanced. These updates enable researchers and engineers to perform large-scale probabilistic seismic hazard and risk calculations more efficiently.
Key updates included in OpenQuake Engine 3.25 are summarized below:
- New default workflow for the global stochastic event set
- Significant performance improvements on multi-core systems
- Optimizations in disk usage and post-processing operations
- New risk outputs and additional GMPE implementations
- Support for Python 3.13
The 3.25 release is considered an important component of the computational infrastructure that will support the global seismic hazard and risk models planned for release in 2026.
For users who require long-term stability, the 3.23.x LTS version continues to be supported.
