ANR Monidas

Natural hazard monitoring using Distributed Acoustic Sensing

The Monidas project will develop Distributed Acoustic Sensing (DAS) technologies geared toward monitoring seismic, volcanic, and landslide
natural hazards.

DAS sensors use standard telecommunication optical fibres to measure the the deformation of cables in the acoustic range of 0.1 to 1kHz. By doing so, a single fibre can act as a dense distribution of sensors over dozen of kilometres

As part of this industry-academic initiative, a new DAS acquisition system will be constructed in partnership with Febus-Optics. This system will then be tested in four key geological settings: on Stromboli volcano, on submarine cables off the coast of Greece, on a landslide site in the Alps, and at an active geothermal site in Alsace, France. These four targets are chosen to represent the four main geological risks faced on French territory. Cutting edge data processing techniques will be used to improve the detection and characterisation of seismic sources, seismo-volcanic deformation, rock-fall, landslides, amongst others.

The ultimate goal of the Monidas project is to provide the French geophysical community with a new instrument, based on technology that has shown promising results in monitoring and data processing.
