    Workshop RESIF – Aléa sismique & Shakemaps 29-31 January 2018, Montpellier, France  Balance Using the USGS de facto standards facilitates data exchange and comparison of results. Advantages of using standard open source modules: cost effective, contribution to the community and high interoperability and expandability. High stability and reliability. After ~ 5 years of operation an upgrade/update is strongly recommended.
