- PublicationRestrictedEIDA: The European Integrated Data Archive and Service Infrastructure within ORFEUS(2021-03-31)
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ;; ; ; ; ; ; ; ; ; ; ;; ; ; ; ; ;; ; ; ; ; ; ;; ; ; ;The European Integrated Data Archive (EIDA) is the infrastructure that provides access to the seismic‐waveform archives collected by European agencies. This distributed system is managed by Observatories and Research Facilities for European Seismology. EIDA provides seamless access to seismic data from 12 data archives across Europe by means of standard services, exposing data on behalf of hundreds of network operators and research organizations. More than 12,000 stations from permanent and temporary networks equipped with seismometers, accelerometers, pressure sensors, and other sensors are accessible through the EIDA federated services. A growing user base currently counting around 3000 unique users per year has been requesting data and using EIDA services. The EIDA system is designed to scale up to support additional new services, data types, and nodes. Data holdings, services, and user numbers have grown substantially since the establishment of EIDA in 2013. EIDA is currently active in developing suitable data management approaches for new emerging technologies (e.g., distributed acoustic sensing) and challenges related to big datasets. This article reviews the evolution of EIDA, the current data holdings, and service portfolio, and gives an outlook on the current developments and the future envisaged challenges.108 62 - PublicationRestrictedPreface to the Focus Section on European Seismic Networks and Associated Services and Products(2021)

Primarily driven by governmental mandates to detect local seismicity and provide earthquake information to civil protection agencies and the general public, this monitoring effort also results in a tremendous amount of high‐quality data—more than 12,000 stations presently contribute to the European Integrated Data Archive (EIDA)—which is made available to scientists and practitioners. This lively community of seismic data providers and users is at the core of the success of this focus section: 30 groups responded enthusiastically to our call for papers, providing high‐quality contributions that describe the state of the art in observational seismology in the greater European region, addressing all components of the life cycle of seismic data, from station design to open dissemination of data and seismological products (Amato et al., 2021; Bono et al., 2021; Bragato et al., 2021; Büyükakpınar et al., 2021; Cambaz et al., 2021; Carrilho et al., 2021; Danecek et al., 2021; Evangelidis et al., 2021; Galea et al., 2021; Heit et al., 2021; Lanzano et al., 2021; Lenhardt et al., 2021; Lund et al., 2021; Mărmureanu et al., 2021; Margheriti et al., 2021; Masson et al., 2021; Mader and Ritter, 2021; Ottemöller et al., 2021; Quinteros, Strollo,et al., 2021; Quinteros, Carter, et al., 2021; Rudzinski et al, 2021; Péquegnat et al., 2021; Schweitzer et al., 2021; Senturk et al., 2021; Shahvar et al., 2021; Spallarossa et al., 2021; Stammler et al., 2021; Strollo et al., 2021; Veikkolainen et al., 2021).207 73 - PublicationOpen AccessCoordinated and Interoperable Seismological Data and Product Services in Europe: the EPOS Thematic Core Service for Seismology(2022-04-29)
; ; ; ; ; ; ; ; ; ; ; ; ; ;; ; ; ; ; ; ;; ; ; ;In this article we describe EPOS Seismology, the Thematic Core Service consortium for the seismology domain within the European Plate Observing System infrastructure. EPOS Seismology was developed alongside the build-up of EPOS during the last decade, in close collaboration between the existing pan-European seismological initiatives ORFEUS (Observatories and Research Facilities for European Seismology), EMSC (Euro-Mediterranean Seismological Center) and EFEHR (European Facilities for Earthquake Hazard and Risk) and their respective communities. It provides on one hand a governance framework that allows a well-coordinated interaction of the seismological community services with EPOS and its bodies, and on the other hand it strengthens the coordination among the already existing seismological initiatives with regard to data, products and service provisioning and further development. Within the EPOS Delivery Framework, ORFEUS, EMSC and EFEHR provide a wide range of services that allow open access to a vast amount of seismological data and products, following and implementing the FAIR principles and supporting open science. Services include access to raw seismic waveforms of thousands of stations together with relevant station and data quality information, parametric earthquake information of recent and historical earthquakes together with advanced event-specific products like moment tensors or source models and further ancillary services, and comprehensive seismic hazard and risk information, covering latest European scale models and their underlying data. The services continue to be available on the well-established domain-specific platforms and websites, and are also consecutively integrated with the interoperable central EPOS data infrastructure. EPOS Seismology and its participating organizations provide a consistent framework for the future development of these services and their operation as EPOS services, closely coordinated also with other international seismological initiatives, and is well set to represent the European seismological research infrastructures and their stakeholders within EPOS.575 8 - PublicationOpen AccessThe European Volcano Observatories and their use of the aviation colour code system(2024)

They often work through consolidated procedures to respond to volcanic crises in a timely manner and provide a service to the community aimed at reducing the potential impact of an eruption. Within the International Airways Volcano Watch (IAVW) framework of the International Civil Aviation Organisation (ICAO), designated State Volcano Observatories (SVOs) are asked to operate a colour coded system designed to inform the aviation community about the status of a volcano and the expected threats associated. Despite the IAVW documentation defining the different colour-coded levels, operating the aviation colour code in a standardised way is not easy, as sometimes, different SVOs adopt different strategies on how, when, and why to change it. Following two European VOs and Volcanic Ash Advisory Centres (VAACs) workshops, the European VOs agreed to present an overview on how they operate the aviation colour code. The comparative analysis presented here reveals that not all VOs in Europe use this system as part of their operational response, mainly because of a lack of volcanic eruptions since the aviation colour code was officially established, or the absence of a formal designation as an SVO. We also note that the VOs that do regularly use aviation colour code operate it differently depending on the frequency and styles of eruptions, the historical eruptive activity, the nature of the unrest, the monitoring level, institutional norms, previous experiences, and on the agreement they may have with the local Air Transport Navigation providers. This study shows that even though the aviation colour code system was designed to provide a standard, its usage strongly depends on the institutional subjectivity in responding to volcano emergencies. Some common questions have been identified across the different (S)VOs that will need to be addressed by ICAO to have a more harmonised approach and usage of the aviation colour code277 12
