A network of 100 nodes was installed for a period of around thirty days as part of the Improve project for imaging and temporal monitoring of the Krafla volcano (Iceland) in the context of geothermal research in conjunction with other methods, particularly electrical and magnetotelluric. The noise is used for imaging and temporal monitoring and event detection. This shot shows the installation of the node network. The team digs a hole to bury the node. The node is buried, oriented north by compass. On the right is the tablet used to communicate with the node and start data acquisition. The network of 100 nodes is installed for a period of around 30 days, representing the node's operating autonomy. The instruments will then be retrieved 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 in charge of monitoring and understanding the dynamic and complex system of the solid Earth. Un réseau de 100 nodes a été installé pour une période d’une trentaine de jours dans le cadre du projet Improve d’imagerie et de suivi temporel du volcan Krafla (Islande) dans un contexte de recherche géothermique en liaison avec d’autres méthodes notamment électriques et magnétotélluriques. Le bruit est utilisé pour l'imagerie et le suivi temporel et la détection ...
