Early tsunami warning system in Chile improves public safety
Chile has reinforced its emergency protocols by launching an advanced early tsunami warning system. The project is a joint effort led by the National Emergency Office of the Ministry of the Interior (ONEMI) and developed by Spanish companies Dominion and Lafcarr.
An innovative system to protect coastal areas
The warning system operates in the regions of Arica, Tarapacá, O’Higgins, Maule, and Bío-Bío. It aims to minimize tsunami risks by alerting residents in vulnerable coastal zones. Authorities can activate the sirens remotely and provide clear evacuation instructions. The system combines electronic sirens, surveillance cameras, and meteorological stations.
Reliable communication and remote control
The technology uses three independent communication channels to ensure continuous operation. Two control centers, located in ONEMI’s regional offices and its central office in Santiago, manage the system. Additionally, portable satellite activation kits guarantee functionality in case of emergencies.
Built for efficiency and resilience
Each siren is mounted on an 11-meter-high steel tower. Solar panels installed at eight meters provide energy autonomy. The entire infrastructure complies with Chilean technical standards, ensuring structural stability and long-term durability.
National expansion plan
The project plans to extend coverage to all tsunami-prone regions in Chile. The goal is to install approximately 850 sirens nationwide. This expansion will improve emergency response capacity and enhance the safety of millions of people living in at-risk areas.
