Tsunami early warning system in Chile to protect coastal areas
Chile has taken a decisive step in emergency management by deploying an advanced tsunami early warning system, developed by Dominion and Lafcarr under the direction of the National Emergency Office of the Ministry of the Interior (ONEMI).
An end-to-end system to mitigate risk
The system, already operational in the Arica, Tarapacá, O’Higgins, Maule and Bío-Bío regions, can immediately alert people living in at-risk areas to a possible tsunami. Through high-power electronic sirens, supported by CCTV cameras and weather stations, the public receives clear instructions to evacuate quickly and safely.
Remote management and redundant communication
The system has three redundant communication channels, ensuring alerts reach people even in adverse conditions. It can be activated from two control centres: the ONEMI regional offices and the headquarters in Santiago. It also has portable cases with satellite connections to guarantee operational continuity.
Infrastructure built to withstand emergencies
Each siren is mounted on a free-standing 11-metre pole, with solar panels at 8 metres, ensuring energy self-sufficiency and structural strength. Everything has been designed and manufactured in line with current Chilean technical standards.
Goal: nationwide coverage
The project aims to extend to every at-risk area of the country through a public-private initiative. Around 850 sirens are expected to be installed in total, strengthening Chile's response to natural emergencies and improving the safety of millions of people.
