EIDA: The European Integrated Data Archive and Service Infrastructure within ORFEUS

Abstract

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.

Indicators for site characterization at seismic station: recommendation from a dedicated survey

“…Further, it can be used to evaluate in a quantitative way the reliability of the indicator's value by computing an overall quality index for the station site (see the companion paper Di , or as a sort of checklist for new efforts in improving notcharacterized networks. The summary reports provided as editable pdf, although they can certainly be improved, constitute a practical tool for network operators and data users to homogenize the content and presentation of site metadata, which is of increasing concern for most of them (e.g., Cauzzi et al 2021;Lanzano et al 2021;Strollo et al 2021).…”

The Transversal Seismicity Action RESIF: A Tool to Improve the Distribution of the French Seismicity Products

“…The bulletin will be made available through the FDSN webservice (http://renass.unistra.fr), identified as the one used by EIDA for French seismicity. Most of the associated waveforms are available from RESIF EIDA node (Strollo et al 2020).…”

RÉSIF-SI: A Distributed Information System for French Seismological Data

“…EIDA offers a wide set of additional services and tools, including smart clients, federated archive access, and web interfaces. A full description of EIDA can be found in Strollo et al (2021).…”

“…In particular, the national data distribution facility is a part of the European Integrated Data Archive (EIDA) federation, a service within ORFEUS that gives federated access to data from European data centers. The EIDA is described in Strollo et al (2021).…”
