Turning Global Connectivity into a New Frontier for Earthquake Monitoring
Sparkle’s submarine fiber-optic network, a backbone of global communications in the Mediterranean, is also revealing its potential as a tool for seismic monitoring. Research shows that variations in light polarization within existing cables can correlate with major earthquakes, even thousands of kilometers away.
While not designed to predict seismic events, this approach demonstrates how digital infrastructure can support scientific research and contribute to a deeper understanding of Earth’s dynamics without altering the primary mission of reliable, high-performance connectivity.
