"We may receive a tsunami warning half an hour in advance"

Observador14 September 2026 at 07:00

José Sousa Barros warned that submarine cables are critical infrastructure that are still not recognized as such. This infrastructure ensures almost 100% of data connections between continents, making it essential for global communications.

During his intervention, José Sousa Barros mentioned that early warning systems may allow receiving a tsunami warning half an hour before the event occurs. This advance notice can be crucial for the protection of coastal populations.

The lack of official recognition of these infrastructures as critical puts at risk the preparation and response to potential threats that may affect submarine cables, which are fundamental for worldwide connectivity.

Why this matters

The Portuguese population, as a coastal country vulnerable to tsunamis, directly benefits from knowing that warning systems may give only 30 minutes' notice, enabling rapid evacuation decisions. The article also highlights the global communications' dependence on submarine cables, an invisible but essential infrastructure for modern life.
