EPOS Seismology: Connecting Communities, Advancing Research, and Paving the Way Forward

We present the dynamic landscape of EPOS Seismology, a Thematic Core Service consortium at the foundation of the European Plate Observing System (EPOS) infrastructure. Cultivated over the past decade through partnerships with prominent pan-European seismological entities, the ORFEUS (Observatories and Research Facilities for European Seismology), EMSC (Euro-Mediterranean Seismological Center), and EFEHR (European Facilities for Earthquake Hazard and Risk), EPOS Seismology stands out as a collaborative governance framework. Facilitating the harmonized interaction between seismological community services, EPOS, and its associated bodies, endeavors to widen the collaboration to include data management, product provision, and the evolution of new seismological services. Within the EPOS Delivery Framework, EPOS Seismology pioneers a diverse array of services, fostering open access to a wealth of seismological data and products while unwaveringly adhering to the FAIR principles and promoting open data and science. These services encompass the archival and dissemination of seismic waveforms of 24,000 seismic stations, access to pertinent station and data quality information, parametric earthquake data spanning recent and historical events, as well as advanced event-specific products such as moment tensors and source models together with reference seismic hazard and risk for the Euro-Mediterranean region. The seismological services are seamlessly integrated into the interoperable centralized EPOS data infrastructure and are openly accessible through established domain-specific platforms and websites. Collaboratively orchestrated by EPOS Seismology and its participating organizations, this integration provides a cohesive framework for the ongoing and future development of these services within the extensive EPOS network. The products and services support the transformative role of seismological research infrastructures, showcasing their pivotal contributions to the evolving narrative of solid Earth science within the broader context of EPOS.
