EARTH TREMOR IN NIGERIA: WHAT IF IT IS THE SIGN OF AN IMPENDING MASSIVE EARTHQUAKE?



For so long we have been told or made to believe that Nigeria is far out of reach of the seismic region. To so many of us we may never have witnessed an earth tremor (a small earthquake of low intensity resulting from underground movement along a fault plane from volcanic activity). Except for imaginary Hollywood blockbuster movies which may readily come to our sub-consciousness, I doubt if any one will ever wish to feel the devastating impact of an earthquake.

Recently the make believe syndrome of a safe-haven Nigeria devoid of seismic waves has been blown away by the wind of reality. Persistent earth tremors in Nigeria in recent times have come to stay. All appropriate agencies of the three tiers of government must be ready to face the unforeseen earthquake phenomenon in no too distant future. The national president (Building Collapse Prevention Guild), Kunle Awobodu few months ago revealed that through a geophysical and geological study, a fault zone that connects with the Atlantic fracture exists along Ifewara in Osun state and Zungeru in Niger state.  Could this be the reasons why areas such as Saki and neighboring towns in Oyo state, some communities which comprises of akenfa, akinma, igbogene in Bayelsa state and Ikara L.G.A in Kaduna state have been witnessing tremor in recent times.? It has been widely reported via various print media that another earth tremor struck Koi town in Jaba local government area of Kaduna state on 11th September, 2016, though no life was lost. Isn’t this enough reason to stir appropriate organs of government to carry out research and investigation on Awobodu’s assertion?



The report of Dr.Adepelumi.A.Abraham, a geologist in the department of geology of Obafemi Awolowo University, Ile-Ife titled “PRELIMINARY ASSESSMENT OF EARTH TREMOR OCCURRENCE IN SHAKI AREA, SHAKI WEST LOCAL GOVERNMENT IN OYO STATE” dated 9th June, 2016 addressed to the Speaker of the green chamber by the member representing Saki-West/Saki-East and Atisbi LGA of Oyo state. Has it been thoroughly examined by the national assembly for necessary implementation or thrown into the dust bin as a matter of no significant importance? It is noteworthy that Abraham’s assertion in his report of a possible earthquake before 2020 with a risk of 91.1percent is a revelation which must put us as Nigerians at the edge of our seat.

How equipped is the Centre for geodesy and geodynamics (CGG) situated in Toro, Nigeria and in coordination with the 4 seismographic network stations located in Kaduna, Nsukka, Ile-Ife and Awka ? Reports have it that the 4 network stations are equipped with a 24-bit-4channel recorders and broadband 30-seconds seismometers. The salient question that needs answer is if a seismographic station exists in Kaduna state with modern facilities, why couldn’t officials of the network station be able to inform the citizens of Kaduna state and its environs of an impending tremor? Same for seismographic network station in Ile-Ife which could not detect the warning signs of tremor in Saki, Oyo state. Earth tremor don’t just occur, there would have been movement and vibration underground for so long. 


The need for collaboration between the National Earthquake Information Centre (NEIC) located in Colorado, USA and Centre for Geodesy and Geodynamics (CGG) with the 4 operational seismographic stations in Nigeria is important for real time updates. One of the primary duties of NEIC is to determine as rapidly and as accurately as possible, the location, size of all significant earthquakes that occurs worldwide, it also disseminates this information immediately to concerned national and international agencies. Early detection is crucial as it will be the saving grace if there is a massive earthquake to prepare us to reduce the loss to the barest minimum possible. Again if the Nigerian government is not satisfied with the research and report of Dr.Abraham on Saki’s earth tremor, it could be submitted to NEIC which also serves as a National data center and archive for earthquake information where further research could be conducted. In all appropriate policies would be recommended to the Nigerian government for implementation.


How prepared is our emergency relief agencies if peradventure Nigeria is hit by an earthquake which I pray God forbids? What will be the average response time? How will the necessary personnel cope during such daunting responsibilities? What orientation do we have as Nigerians concerning earth tremor and earthquake? There are so many questions begging to be answered. In all superintending organs of government should be prepared by simulating earthquake like situations to train those who needs to be trained. Finally I am not a prophet of doom but a patriotic Nigerian worried about the ever changing course of nature. No one will have ever imagined that terrorism and kidnapping will be the order of the day in Nigeria 30 years ago but today it is an ugly menace we were never prepared for. GOD BLESS NIGERIAN MY COUNTRY.
