The Nigerian Institution of Structural Engineers has raised fresh concerns over Nigeria’s vulnerability to earthquake-related damage, identifying major cities such as Lagos, Ibadan, Abeokuta, and Benin City as potentially at risk.
The warning was issued by former president of the institution, Olushola Sanni, who noted that many buildings across the country were constructed without proper engineering oversight or consideration for seismic forces.
Sanni explained that while Nigeria is generally regarded as a low seismic-risk zone, it is not entirely immune to earth tremors, cautioning against complacency due to the absence of major earthquakes in recent years.
“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,” he said.
He referenced recent global incidents to illustrate how earthquake vibrations can travel hundreds of kilometres, causing damage even in areas far from the epicentre.
According to him, most structures in Nigeria are not designed to withstand seismic activity, exposing residents to potential danger, especially in cities built on soft soil formations.
He also pointed to seismic activity in neighbouring Ghana, particularly around Accra, noting that geological formations along the West African coastline cut across national borders and could transmit seismic energy into parts of southwestern Nigeria.
To address the risks, Sanni disclosed that the institution plans to introduce new guidelines for earthquake-resistant building design in Lagos on April 16, 2026.
The proposed framework aims to align Nigeria’s construction practices with global safety standards and promote the adoption of safer building techniques, including balanced designs, stronger structural connections, and proper reinforcement detailing.
He urged stakeholders in the construction sector to prioritise structural safety, stressing that proactive measures are critical to reducing potential damage and safeguarding lives.
