NASRDA DG Presents Critical Insights on Earth Tremors and Flood Risks in Nigeria
During a recent ministerial press briefing, Dr Matthew Adepoju, the Director General of the National Space Research and Development Agency (NASRDA) provided a detailed presentation on the earth tremors that occurred in Mpape, Abuja, and the potential flood risks from the Lagdo Dam in Cameroon. Dr Adepoju demonstrated the crucial role of satellite imagery and data in monitoring these events. Additionally, he highlighted how this information can help prevent disasters if prompt action is taken.
The DG used satellite-based insights to explain the cause of the September 16, 2024, earth tremor, attributing it to gradual strain withdrawal and fault reactivation within the region. He stressed that NASRDA’s seismic data from its Centre for Geodesy and Geodynamics in Toro was instrumental in tracing the tremor’s exact cause. This allowed for more accurate predictions of potential future events. Additionally, he highlighted NASRDA’s efforts to strengthen seismic monitoring capabilities across Nigeria by deploying GNSS receivers. These receivers will be installed nationwide. They will complement existing seismic stations and provide a more comprehensive data set for predicting seismic events. Furthermore, Dr Adepoju reiterated the need for continuous monitoring and data analysis to develop early warning systems. He further stressed that proper funding is essential to expanding these capabilities.
Satellite Data for Flood Monitoring
At the same briefing, Dr Adepoju presented satellite imagery showing that the overflow of the Lagdo Dam had already affected approximately 137 hectares of land, heightening the flooding risk in southern Nigeria. He noted that while the flooding could have serious consequences, implementing the proper precautionary measures could prevent large-scale devastation. The data collected under the United Nations Space-based Information for Disaster Management and Emergency Response, hosted by NASRDA, was vital in identifying these risks.
In conclusion, Dr Adepoju thanked the federal government for supporting the building of seismic stations and urged continued investment to strengthen NASRDA’s disaster-prevention (and early warning) efforts. He assured that NASRDA remains fully committed to its mandate of enhancing national safety through space-based technology and data.
The Ministry of Innovation, Science, and Technology held this briefing to update the public on the detailed investigation into the recent earth tremors in Mpape and address the flooding concerns in some parts of Nigeria. In addition, they reassured the public that a team of experts from NASRDA and other relevant departments is working around the clock to study these issues and provide vital data to help manage such risks.
