The Nigerian Institution of Structural Engineers has raised concerns over Nigeria’s susceptibility to earthquake-related damage, identifying major cities such as Lagos, Ibadan, Abeokuta, and Benin City as potentially at risk.
A former president of the institution, Olushola Sanni, issued the warning, noting that a significant number of buildings across the country were constructed without adequate engineering oversight or consideration for seismic forces.
He referenced recent global incidents to highlight how earthquake vibrations can travel vast distances, sometimes hundreds of kilometres, leading to damage and widespread panic even in areas far from the epicentre.
Sanni explained that although Nigeria is generally classified as a low seismic-risk zone, it is not entirely immune to earth tremors. He warned that the absence of major earthquakes in recent years should not create complacency.
According to him, most structures in the country are not designed to withstand seismic activity, thereby exposing residents to potential danger.
To address this gap, he disclosed that the institution is set to introduce new guidelines for earthquake-resistant building design in Lagos on April 16, 2026.
The framework, he said, is intended to align Nigeria’s construction practices with global safety standards.
“Earthquakes do not recognise geographical boundaries, and distance from the source does not guarantee protection. The lack of recent seismic events should not give a false sense of security,” Sanni stated.
He also pointed out that neighbouring Ghana has experienced several earthquakes, particularly around Accra, stressing that geological formations along the West African coastline cut across national borders.
This, he explained, suggests that seismic energy from that region could extend into parts of southwestern Nigeria.
Sanni further warned that cities situated on soft soil formations, including Lagos, Ibadan, Abeokuta, and Benin City, could experience intensified ground shaking if seismic waves reach them.
He therefore called for the adoption of earthquake-resistant construction practices, urging stakeholders to prioritise structural safety in building design.
According to him, the proposed guidelines will provide simplified procedures for engineers while promoting international best practices. He added that safer structures should incorporate balanced designs, strong structural connections, and adequate reinforcement detailing.
