Risk analysis is a critical link in the reduction of casualties and damages due to earthquakes. Recognition of this relation has led to a rapid rise in demand for accurate, reliable and flexible risk assessment numerical tools and software. As a response to this need, the Global Earthquake Model (GEM) initiated the development of an open source platform called OpenQuake for calculating seismic hazard and risk at any scale. In this paper a description of the architecture of OpenQuake is provided, highlighting the current workflow of the main loss calculators. In addition, a case study is presented using the Marmara Region (Turkey) for the calculations.
