The Nigerian Geological Survey Agency has assured that it is in control of the earth tremor that rocked Mpape, located outskirts of Nigeria’s capital city, Abuja on the 5th of September.
Speaking to newsmen on Friday in Abuja, Alex Nwaegbu, director general of the Nigerian Geological Survey Agency, said the agency has since dispatched a team of geologists and geophysicist on a fact finding mission.
Giving further insight on the preliminary findings, the director general said,”analysis of regional airborne geophysical data has identified the area to have undergone series of tectonic activities leading to structural emplacement.
“Some of these structures are deeply seated,broad and extensive and could serve as good channels for stress dissipation,” he noted.
The preliminary investigations, the director general therefore associated the tremor to quarrying in the area which involve intense blasting that led to stress accumulation.
“The accumulated stress was then released as seismic energy triggering the ground shake,” The Geological Survey Agency’s helmsman said.
He noted further that the stress may have travelled through secondary fractures to other areas where the intensity of the tremore is estimated to be between 3 and 3.5 on the Modified Mercalli Scale since the investigating team did not observe any visible damage such as cracks,shuttering on windows or colouration in ground water.
The Nigerian Geological Survey Agency said it’s team of Engineers should keep a close monitoring team within the next 48 hours within which arrangement ought to have been concluded in the area involving reflection seismic and gravity measurement to fully unravel immediate and remote causes of the tremor.
It would be recalled that from the account of the preliminary findings by the Nigeria Geological Survey Agency team,”The vibration started around 2:30pm on 5th September,2018 which lasted about a second but reoccurred 3 hours later around 5:30pm. The vibration was again felt around 8.00pm which lasted for about 10 seconds.
The Federal government as a result of this development rolled out emergency numbers for calls in case of any tremor anywhere across the country to include:08035956056,08023154825,08037000623.
