The Nigerian Institution of Structural Engineers has raised concerns about Nigeria’s vulnerability to earthquake-related damage, warning that major cities including Lagos, Ibadan, Abeokuta and Benin City could face heightened risk due to weak structural preparedness.

A former president of the institution, Olushola Sanni, said many buildings across the country were constructed without adequate engineering oversight or consideration for seismic forces, increasing their vulnerability in the event of earth tremors.

He noted that although Nigeria is generally regarded as a low seismic-risk zone, it is not immune to earthquakes, cautioning that the absence of recent major tremors should not create a false sense of safety.

Sanni explained that seismic vibrations can travel hundreds of kilometres from their source, sometimes causing damage and panic in locations far from the epicentre.

He also pointed to recurring earthquake activity around Accra, warning that geological formations along the West African coastline extend across national borders and could transmit seismic energy into parts of southwestern Nigeria.

According to him, cities built on soft soil formations, including Lagos, Ibadan, Abeokuta and Benin City, may experience intensified ground shaking if seismic waves reach those areas.

To improve preparedness, Sanni disclosed that the institution will introduce new guidelines for earthquake-resistant building design in Lagos on April 16, 2026, aimed at aligning Nigeria’s construction practices with international safety standards.

“Earthquakes do not recognise geographical boundaries, and distance from the source does not guarantee protection,” he said, urging stakeholders in the construction sector to prioritise structural safety.

He added that the proposed framework would promote balanced structural designs, stronger connections and improved reinforcement detailing to enhance building resilience across the country.
