The organization of Structural Engineers in Nigeria has raised an alarm over the nation’s threat to earthquake-related destruction.
It specifically pointed out key cities like Lagos, Ibadan, Abeokuta, and Benin City as possible areas at danger.
Olushola Sanni, erstwhile president of the institution made this disclosure, insisting that a significant number of buildings across the country were constructed without sufficient engineering oversight or consideration for seismic forces.
He cited recent global incidents to explain 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 said that even though Nigeria is classified as a low seismic-risk zone, it is not totally inoculated to earth tremors.
He admonished that the absence of key earthquakes in years past should not be taken for granted.
He further maintained that most structures in the country are not designed to repel seismic activity, thereby exposing residents to potential risk.
But to overcome the looming danger, he said the institution is set to introduce new guidelines for earthquake-resistant building design in Lagos on April 16, 2026, a framework which he
is intended to align Nigeria’s construction practices with global safety standards.
In his words, “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 cited that Ghana, a nearby country has experienced several earthquakes even 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 also opted for the adoption of earthquake-resistant construction practices, saying stakeholders should prioritise structural safety in building design and
provide simplified procedures for engineers while promoting international best practices.
