National EPOS initiatives and participation to the EPOS integration plan

European Plate Observing System (EPOS) is designed on a three-level architecture. The national research infrastructures (NRIs) constitute the backbone of EPOS delivery framework, where data are generated, processed, analyzed and archived. These then integrated by thematic core services (TCS) distributed through centralized (ICS). In this architecture, provision from NRIs an essential element for sustainable operation infrastructure (RI). National initiatives in various countries Europe developed thanks to increased awareness importance FAIR (Findable, Accessible, Interoperable Reusable) management science. As such, out 14 (13 members one observer) that Research Infrastructure Consortium (EPOS-ERIC), 11 have dedicated consortia established included roadmaps infrastructures. Moreover, there total 24 involved framework 10 not yet EPOS-ERIC. However, diversity regulations procedures adopted different countries, hampers development contributing sustainability. paper, discussed order emphasize synergies achieved shared efforts build RI during its life-cycle (the design, preparation, implementation, pilot operational phases), tackling challenge operation.
