Abstract

AbstractThe Résif project, which started in 2008, aims at gathering under a common research infrastructure the French seismological, Global Navigation Satellite Systems and gravimeter permanent networks, as well as the mobile instrument pools. A central part of Résif is its seismological information system, Système d'Information de Résif (Résif-SI) (started in 2012), which is in charge of collecting, validating, archiving, and distributing seismological data and metadata from seven national centers. Résif-SI follows a distributed architecture, in which the six data collection and validation centers (A-nodes) send validated data and metadata to a national data center (Résif Data Center [Résif-DC]), which is the central point for data archiving and distribution. Résif-SI is based on international standard formats and protocols, and is fully integrated into European and international data exchange systems (European Integrated Data Archive, European Plate Observing System [EPOS], Incorporated Research Institutions for Seismology, International Federation of Digital Seismograph Networks). In this article, we present the organization of Résif-SI, the technical details of its implementation, and the catalog of services provided to the end users. The article is aimed both at seismologists, who want to discover and use Résif data, and at data center operators, who might be interested in the technical choices made in the implementation of Résif-SI. We believe that Résif-SI can be a model for other countries facing the problem of integrating different organizations into a centralized seismological information system.

Highlights

Réseau sismologique et géodésique français – French seismological and geodetical network (Résif, see Data and Resources) started as a project in 2008, with the aim of grouping into a single research infrastructure all the major national and regional seismic, the Global Navigation Satellite Systems (GNSS), and gravimeter permanent networks and mobile pools in France
GNSS data from all Résif partners are distributed from the national Résif data center for GNSS data (Résif, 2017), which hosts the EPOS GNSS data gateway, whereas, the Résif data from permanent gravimeters are directly integrated into dedicated international data centers (Voigt et al, 2016)
The statistics can be accessed through several means: we provide a webservice for end users and interactive dashboards for internal usage

Summary

Introduction

Réseau sismologique et géodésique français – French seismological and geodetical network (Résif, see Data and Resources) started as a project in 2008, with the aim of grouping into a single research infrastructure all the major national and regional seismic, the Global Navigation Satellite Systems (GNSS), and gravimeter permanent networks and mobile pools in France. Seismological data and metadata are collected and validated by six centers run by Résif partners which are called "A-nodes" (Fig. 2), which are responsible to secure a copy of the data for two years.
