OpenQuake at 15: Powering Resilience in a Risk-Prone World

This year marks the 15th anniversary of the OpenQuake Engine, GEM’s open-source software for seismic hazard and risk assessment. Since the start of open source development in 2010 and the release of the first version in 2014, the Engine has grown into a globally recognised platform used by scientists, engineers, insurers, and policymakers across continents. Its evolution reflects not only advances in modelling but also the growing need to translate science into tools that strengthen resilience in communities at risk.
