Lisbon installs a pioneering early warning system in the Tagus estuary
Portugal is taking a decisive step in natural hazard prevention. The Lisbon Metropolitan Area has awarded a specialist Spanish company the installation of an advanced tsunami detection and warning system, improving safety in one of the country's most vulnerable areas. The innovative early warning system will protect the whole coastline from Setúbal to Cascais, a densely populated area exposed to seismic activity. The decision follows the region's most significant earthquake in two decades, of magnitude 4.9, which renewed awareness of the urgent need for effective prevention and evacuation systems.
What does the new tsunami warning system include?
The project involves robust, scalable infrastructure designed to respond within seconds to a real threat. The system includes:
- Four high-power electronic sirens covering the whole of Lisbon bay.
- Two redundant control centres with room for future expansion.
- A resilient telecommunications network to keep transmitting even in adverse conditions.
- Direct integration with the warning system already operating in Cascais.
Acoustic studies and technical analyses will also be carried out to determine the best location for each component in the 18 municipalities involved.
Lisbon looks ahead: preventing possible disasters
The project was developed urgently, reflecting growing concern among institutions, scientists and civil protection services about the possibility of another major seismic event, similar to the devastating 1755 earthquake and tsunami.
“Another disaster like 1755 is not a question of if, but when,” warns researcher José Luís Zêzere of the Institute of Geography and Spatial Planning.
In this context, state-of-the-art technology for tsunami detection and warning in Portugal is not only a strategic necessity but a key tool for saving lives.

Engineering that anticipates the unpredictable
At Lafcarr we turn technical knowledge into real solutions for natural and technological risks. For more than two decades we have developed and integrated early warning systems combining electronic sirens, smart sensors and management platforms such as our own iDAM software.
iDAM is a modular platform developed by Lafcarr for end-to-end control of warning systems. It monitors events in real time, automates responses to multiple threats and centralises management from mobile devices or control centres. It is designed for both urban settings and critical infrastructure.
Taking part in this strategic project in Lisbon reinforces our commitment to public safety on coasts exposed to extreme events such as tsunamis. And it shows that anticipation, when based on reliable technology and robust design, saves lives.
Is your municipality ready for an extreme event?
Assessing exposure and response capability for events such as a tsunami in Portugal is more urgent than ever. Lafcarr helps you diagnose, size and deploy solutions tailored to each area.
