Ocean Cables to Provide Early Earthquake, Tsunami Warnings

• 1.5 million KM long fiber optic internet cables can now detect seismic activity and tsunamis.
• Scientists developed technology to sense even slight movements beneath the sea, offering lifesaver for coastal areas.
• The 'Fiber Optic Cable Use for Seafloor' (FOCUS) project successfully tested this in the Mediterranean Sea near Sicily.
• Laser light technology detects pressure changes on cables, indicating tectonic movement and fiber stretching.
• Commercial internet cables can also be repurposed as a global sensor network, providing early warnings for disasters and monitoring sea temperature changes.
