In mid‑January 2022, the Pacific island nation of Tonga was struck by the powerful eruption of the Hunga Tonga–Hunga Ha’apai submarine volcano, followed by a tsunami that caused widespread disruption across the archipelago. While physical damage was significant, one of the most critical impacts was the destruction of both international and domestic submarine communication cables, effectively isolating the country from the rest of the world.

With internet and telecommunications services largely unavailable for weeks, government authorities and humanitarian actors were forced to rely on limited and slow satellite communications, severely constraining coordination, public services, and disaster response mechanisms. In this context, the World Food Programme (WFP), leading the Emergency Telecommunications Cluster (ETC), requested high‑capacity connectivity support from emergency.lu.

Responding rapidly, Luxembourg configured and deployed two complete Ranger VSAT systems equipped with NoSaCo communication racks and spare parts kits. The equipment was transported as humanitarian cargo from Luxembourg and Dubai to Brisbane, before onward shipment to Tongatapu, where it was managed and stored by WFP for deployment.

The systems were then installed at key operational sites:

• One Ranger terminal was established in the Emergency Operations Centre (EOC) in Neiafu, Vava’u, becoming operational in August 2022 after final configuration and site adjustments
• A second system was prepared for deployment in Ha’apai, one of the most affected island groups, to extend connectivity further across the archipelago

The deployment provided shared satellite internet connectivity for:

• Government authorities, including the Ministry of Meteorology, Energy, Information, Disaster Management, Environment, Climate Change and Communications (MEIDECC)
• UN agencies and humanitarian partners
• Response coordination structures operating in multiple island locations

Luxembourg’s technical teams supported the mission through:

• Configuration and system preparation before deployment
• Providing antenna pointing procedures and setup guidance
• Remote technical support during installation and operation
• Facilitating system upgrades and eventual repatriation after mission completion

By restoring reliable connectivity, emergency.lu enabled:

• National coordination and decision-making during the response phase
• Continuity of public services and communications
• Effective humanitarian coordination across isolated islands

In a country where geographic isolation magnifies the impact of infrastructure failure, the rapid deployment of high-capacity satellite systems proved essential. The Tonga operation highlighted emergency.lu’s ability to restore international connectivity in complete communication blackouts, ensuring that even the most remote island states can remain connected and supported during major disasters.
