Monaco, located in a seismically active zone, has implemented stringent building regulations to safeguard against potential earthquakes…

With a history of tremors in the region, most recently felt in September, concerns over seismic preparedness are ever-present. In response, Monaco has adopted strict earthquake-resistant standards set forth by a 2016 ministerial decree, which requires new constructions to meet rigorous structural guidelines.

Pascal Rouanet, head of Monaco’s Urban Planning and Mobility Prospective Department, explains that Monaco’s legislation is based on French regulations but includes adaptations specific to the Principality. Among these adaptations is the use of “microzoning,” which offers finer granularity in mapping seismic risk zones across the small city-state. Additionally, Monaco has developed a “reference earthquake” model—a 6.5 magnitude quake with an epicenter just 30 kilometers from the Principality—to guide building standards.

Architect Jean-Pierre Lott, responsible for iconic Monaco structures like the Simona Tower, notes that construction projects in Monaco must include comprehensive structural planning, complete with risk assessments. Every permit application must provide detailed designs and structural calculations validated by an independent control office, ensuring all planned constructions can withstand seismic impacts. Lott also mentions specific construction techniques, such as closer placement of expansion joints, allowing buildings to better absorb shocks.

Once construction is completed, authorities conduct inspections to verify compliance with seismic regulations. According to Rouanet, every new building in Monaco undergoes a thorough review before being certified for occupancy.

For older buildings built before 2016, Rouanet assures residents that the Principality has maintained seismic regulations since 1966, ensuring a baseline of safety standards for all structures. In sum, Monaco’s approach is comprehensive, providing the Principality with the resilience needed to face potential seismic challenges.
