Installation of a Node-type sensor as part of the Improve project (Iceland)

This image shows the installation of a seismic node sensor. In the foreground, you can see the tablet used to start up and communicate with the node, as well as to start data logging. The node is buried, oriented north by compass. The network of 100 nodes is installed for a period of around 30 days,...

Description
Summary:This image shows the installation of a seismic node sensor. In the foreground, you can see the tablet used to start up and communicate with the node, as well as to start data logging. The node is buried, oriented north by compass. The network of 100 nodes is installed for a period of around 30 days, representing the node's operating autonomy. The instruments are then recovered and returned to the laboratory for data extraction, conversion and formatting. The instruments belong to the national mobile seismological park (SisMob), which is part of Epos-France, a research infrastructure (RI) in the Solid Earth field, dedicated to observation. Its aim is to advance our knowledge of the Earth system in all its diversity and complexity. In October 2023, Epos-France took over from the French seismological and geodetic network Résif-Epos, which deployed modern instrumentation (seismometers, GNSS stations and gravimeters) across France to measure deformations of the Earth's surface. All French research on the solid Earth will gradually join the IR Epos-France, which represents the French participation in EPOS, the European research infrastructure whose mission is to integrate national and transnational IRs tasked with monitoring and understanding the dynamic and complex system of the solid Earth. Cette image montre l’installation d’un capteur sismologique de type « node ». Au premier plan, on voit la tablette servant à démarrer et dialoguer avec le node ainsi qu’à démarrer l’enregistrement des données. Le node est enterré, orienté vers le nord à la boussole. Le réseau de 100 nodes est installé pour une période d’une trentaine de jours, représentant l’autonomie de fonctionnement du node. Les instruments sont ensuite récupérés et retournés au laboratoire pour l’extraction, la conversion et la mise en forme des données. Les instruments appartiennent au parc national sismologique mobile (SisMob), qui est intégré à Epos-France, une infrastructure de recherche (IR) dans le domaine Terre solide, dédiée à l’observation.
