Following the magnitude 5.4 earthquake that occurred on 11th November 2019 near the town of Teil, west of Montélimar, ADTIM—a subsidiary of Axione and delegate of the Ardèche Drôme Numérique (ADN) public network—provided optical fibre for the Centre National de la Recherche Scientifique (CNRS).

Thanks to this operation, researchers were able to use acoustic detection technology that allowed them to measure ground movements.  

Axione teams, on behalf of ADTIM, carried out optical fibre alignment work on a road near the municipality of Teil, west of Montélimar in the Ardèche department. The total distance of this link comprised 13km of optical fibre.

Thanks to the provision of this infrastructure, scientists from the CNRS’ Géoazur laboratory were able to install “acoustic detection” equipment. This measurement tool was developed by the “Febus Optics” company, and it allows for the detection of ground movements using a monitoring system in order to anticipate and prepare for possible earthquake aftershocks. 

This project demonstrates the importance of our role as a contributor to regional development and as a public service delegate.  We were able to make our expertise available in record time in order to help manage this crisis and meet the needs of the region’s stakeholders. The 4 employees involved carried out the necessary work in just a few days. Normally, this type of operation takes longer.”

David Lentheric, Director of ADTIM

This operation displays Axione’s expertise and adaptability in managing unique and innovative projects.

This initiative highlights the usage potential of optical fibre. In the future, we could foresee continuing our work with the CNRS in order to roll out this type of project in other seismic risk areas.”

concludes David Lentheric.

The future looks bright for fibre!
