On March 25, 2026, the municipality of Lisbon (Portugal), in collaboration with civil protection authorities, conducted the “LisbonWave2026” exercise in the riverside area of the Portuguese capital. Between 10:30 a.m. and 12:00 p.m., four alarm sirens sounded in exposed areas, including Praça do Império and Doca de Alcântara, accompanied by voice messages in Portuguese and English urging the population to move to safety. This exercise aims to prepare residents and tourists for the seismic and tsunami risks threatening Lisbon, whose history has already been deeply marked by such disasters. By 2029, the network is expected to expand to ten sirens to cover the entire waterfront.
