Workshop RESIF – Aléa sismique & Shakemaps 29-31 January 2018, Montpellier, France Project: Interreg IVa 2007-2013 France-Spain-Andorra Participants: IGN, ICGC, BRGM, OMP, UPC, BCSF Objective of the project: “Set up a common system for earthquake data acquisition and scientific resources sharing to improve the management of seismic crisis in the Pyrenees.” Objective of the WP: Automatic computation, plotting and dissemination of an homogeneous cross-border sequence of shakemaps, during the minutes/hours after the occurrence of a M≥2.9 earthquake in the Pyrenean region
Workshop RESIF – Aléa sismique & Shakemaps 29-31 January 2018, Montpellier, France Functional Requirements/Abilities: Use intensities and waveforms (vel + acc) of different agencies (cross-border). Include soil effects. Include regional attenuation laws (GMPEs, IPE and GMICEs). Fully automatic system, but with the ability to be interactive. Continuous coverage in the Pyrenean region. Data update (ability to produce shakemaps sequences). Dissemination of results (I, PGA, PGV and SA).

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.
Workshop RESIF – Aléa sismique & Shakemaps 29-31 January 2018, Montpellier, France Future lines of work Update the USGS Shakemap system to V4. Add ability to retrieve data (waveforms and stations metadata) from servers supporting FDSNWS standards. Add web server capabilities (parametric search, dynamic maps, etc…) Integrated database within the web server to provide new functionalities. Extend the region of study towards the south.
