Description
The GEM Foundation aims to combine the main features of state-of-the-art science, global collaboration and buy-in, transparency and openness in an initiative to calculate and communicate earthquake risk worldwide.
One of the first steps towards this objective has been the open-source development and release of software for seismic hazard and risk assessment called the OpenQuake engine.
This software comprises a set of calculators capable of computing human or economic losses for a collection of assets, caused by a given scenario event, or by considering the probability of all possible events that might happen within a region within a certain time span.
Since its initial release in 2013, the OpenQuake engine remains as one of the most important products released by the GEM Foundation, and it has become the benchmark software for seismic hazard and risk calculations worldwide.
