How submarine fiber-optic infrastructure is being repurposed for real-time earthquake and tsunami monitoring
The world’s ocean floors are crossed by approximately 1.5 million kilometers of submarine fiber optic cables. Originally designed for digital communications, this vast network is now emerging as an unprecedented tool for monitoring earth’s natural phenomena. Sparkle is at the forefront of this transformation, converting existing submarine infrastructure into sophisticated early warning systems for earthquakes and tsunamis.
