Recent earthquakes have been reported in parts of Abuja, raising fears among residents for their safety.
A few weeks ago, the director general of the National Geological Survey Agency (NGSA), Alex Nsegbu, said Nigeria was not on the verge of earthquakes, but a new report from the National Agency Space Research and Development (NASRDA). ) identified communities in four states and Abuja as places where a major earthquake could occur in the country.[irp]
NASRDA’s general manager, Professor Seidu Mohammed, revealed this on the sidelines of the second engineer. Brig. General M.O Agu (rtd) Annual Conference in Abuja Thursday.
Professor Mohammed, who was also chairman of the Presidential Committee on the Abuja Tremor, said that Mpape in Abuja, Kwoi in Kaduna, Ijebu-Ode in Ogun, Shaki in Oyo and Igbogene in Bayelsa would probably be the main earthquakes. not taken.
The old system of inactive faults in the country is becoming active, he said, “what makes the earthquake likely now” in and around the country. According to him, a number of incidents in these places also indicate that a great disaster may occur, calling on the federal government to do something quickly to avoid it.
He said the analysis of the nearly 100-year-old data by members of the Presidential Committee on the Abuja Tremor showed that Mpape in Abuja is a hotspot that is very sensitive to earthquakes and other earthquakes .
“This means that we need an in-depth study across the country to identify these hotspots so we can continually monitor them from satellite systems and spatial data,” he said.
He added that the high volume of water taken from more than 110,000 wells dug in Abuja further aggravates the situation in the capital. “More than 330 tons of water collected daily in Abuja cause a vacuum; puts the earth to the test, “he said.
He urged the FG to look into the indiscriminate drilling of boreholes, calling for comprehensive regulations on the drilling of the earth. He also stated that engineers should now be aware of the likely earthquakes in the design and construction of buildings.
Last week, the Presidential Committee on Abuja Tremor said Nigeria was now exposed to seismic risks, which make the earthquake a potential disaster for the country.
The committee revealed it when the report of its findings was presented to the Minister of Science and Technology, Dr Ogbonnaya Onu. “Nigeria is now exposed to seismic hazards as a result of recent earthquakes in 2016 in Kwoi, Kaduna State, Saki, Oyo State and Iggs in Bayelsa State.
He said, however, that “these earthquakes may have been small, it is now certain that earthquakes have become a potential danger to the nation”.
The committee referred to Julius Berger’s report on the geological, hydrological and geotechnical study in Abuja, which identified Mpape as a weak shear zone with several fracture and fault systems.
He added that water extraction and recharge imbalance in the aquifer cause hydrological instability along fractures. The existence of 110,000 boreholes in the metropolis of Abuja, with about 330,000 metric tons of water drilled every day, is not appropriate, the statement added.
In view of the difficulties which hinder the effectiveness of the prediction, detection and monitoring of earthquakes in Nigeria, the Committee recommended the acquisition and installation of more seismometers and GPS sensors / equipment for the enlargement and networking of the national network of seismographic stations in Nigeria.
The committee also recommended a detailed seismotectonic study using state-of-the-art equipment in the region and throughout the country.
