Portugal to detect tsunamis faster with new Atlantic Cable
Summary and headline written by AI from the source article. How we work
Engineers in Portugal are preparing to utilize the Smart Atlantic Cable, a new undersea cable, to detect earthquakes and tsunamis in the ocean and transmit warnings to land almost immediately.
José Sousa Barros, a telecommunications engineer, explained that this technology could provide warnings of approaching tsunamis up to 30 minutes before they reach the shore, potentially giving communities valuable time to prepare.
The cable will not only aid in disaster preparedness but also transmit data about climate change and other scientific observations in real time. The network of submarine cables, which carry 98% of global internet traffic, functions similarly to nerves in the human body, providing an essential link for modern communication. Portugal’s location between Europe, Africa, and the Americas makes it a key hub for these cables, with 10% of the world’s network passing through the country.
While satellites were once the primary method of intercontinental communication, fiber optic cables now offer much faster speeds and greater bandwidth. Barros emphasized the importance of classifying submarine cables as critical infrastructure to ensure their protection from damage and cyberattacks. He also noted the potential for establishing monitored zones where activities like anchoring and bottom trawling are restricted to safeguard the cables.
The new Atlantic Cable represents a significant investment that could save lives and provide a substantial return by enabling quicker responses to natural disasters.
