Corinth Rift Laboratory - Optic Instruments


Not open in the 1st call.


Host Institution:

National Observatory of Athens (NOA), Greece


Corinth Rift Laboratory is an EPOS Near Fault Observatory (NFO), developed under a French-Greek collaboration. It monitors the fastest opening rift in the Euro-Mediterranean region with several M>6 earthquakes per century. With more than 60 instruments (seismometers, GNSS, strainmeters, tide gauges, meteorological), it is possible to track and interpret the dynamics of the seismicity and the deformation related to fluid pressurization and circulation at depth. Thanks to frequent earthquake swarms, lasting days to months, it has been discovered that some faults exhibit dual behaviour, with transient creep and pore pressure diffusion. Most data and products from CRL are distributed through EPOS. In addition, new instrumentation is planned at CRL, with additional monitoring by fiber optic systems (DAS, BOTDR, innovative strainmeters and electrometers) and high frequency GNSS.

Services offered:

The infrastructure is offering to provide access for developing new experiments based on the deployment, testing, and performance evaluation of optical instruments for seismic and strain measurements (DAS, BOTDR, high resolution optical strainmeters based on Fabry-Perot interferometry, rotational sensors, optical tiltmeters).
Those experiments will provide a unique opportunity to investigate seismic/aseismic coupling, seismicity, and the associated role of fluids. The full or down-sampled data collected during the experiments will be integrated into the seismological VAs in WP2.

Modality of access:

The unit of the physical access to TA services is “1 week”. TA will be offered for in-person access to install instruments and to collect data. Some of the relevant instruments (DAS, BOTDR interrogators, rotational seismometer, and HF GNSS stations) can also be provided by the facility.


The support offered is accessibility to various long optic fibers, transportation, and insurance of the equipment, field installation and de-installation, remote control through the internet, and real-time telemetry of the records.

Additional information:

The infrastructure is about to be upgraded in the short term.
