Sparkle and INGV collaborate on subsea cable research

Sparkle and INGV collaborate on subsea cable research is profiled by BTW Media because public-source evidence links it to internet infrastructure, governance, operational dependencies, or market visibility.

• Sparkle and the National Institute of Geophysics and Volcanology (INGV) have signed a Memorandum of Understanding to explore using Sparkle’s subsea fiber optic cables to detect seismic activities like earthquakes and volcanic eruptions.
• Initial experiments utilizing the Mednautilus cable system’s 11,000 km network have demonstrated the ability to monitor mechanical vibrations and locate seismic events more accurately, setting the stage for advanced early warning systems for natural disasters.

What happened: Sparkle and INGV’s pioneering subsea cable collaboration

Sparkle, in partnership with the National Institute of Geophysics and Volcanology (INGV), has signed a Memorandum of Understanding to explore the potential of using subsea fiber optic cables for seismic event detection. This collaboration, leveraging Sparkle’s existing telecommunications infrastructure, aims to refine fiber-sensing techniques that could detect earthquakes, volcanic eruptions, and anomalous waves through mechanical vibrations impacting the cables.

The research focuses on the MedNautilus cable system, an extensive network stretching 11,000 km across the eastern Mediterranean. Initial tests have already been conducted to measure changes in the state of polarization of optical signals within the cables, which could help map submarine movements and more accurately pinpoint the epicenter of marine earthquakes.

With this agreement, Sparkle and INGV commit to further experiments, enhancing the capability to provide early warnings for tsunamis and earthquakes. This research not only aims to improve natural disaster response but also involves collaboration with other organizations like the National Underwater Dimension Pole (PNS) in La Spezia.
