Its all points to one thing; Poor governance and leadership!... We are our own government.... We provide almost everything for ourselves..from water,electricity,roads,housing etc |

emmanuelpopson: I can see you are a Geologist. So lets talk Geology. It is true that we were taught that much of the African Plate is Seismically stable especially our part of the plate. Where are the seismically active zones? The Plate boundaries. Are we at or close to any major plate boundaries ? No. Now, I would personally use the word ''dormant'' to describe the Seismicity of much of Nigeria particularly where we have the basement complex. Why ''dormant''? There are strike slip faults that exist within the Ibadan Unit and North Central Basement complex. Faulting is an indication of seismic activities. It simply means those zones were once seismically active before gaining equilibrium. When something is dormant in this context it simply means it was once active in times past and can become active at any time in the future. We could be close to that future as we are already beginning to see indications from Ogun, Oyo (part of the Ibadan Unit) and Abuja and Kaduna (Part of North Central Basement Complex). The case of Bayelsa may just be due to human activities like Oil Exploration and exploitation. Now, on the issue of indiscriminate sinking of Bore-Holes as a remote cause. It is very possible but not likely a major cause. Bore-Holes no matter how Deep are too relatively shallow for the effect of ground water extraction to cause a major in-balance in the Earth's subsurface. These water are typically found in the interstitial spaces of acquifers. Mother nature has made it such that there is never vaccum. The draw down created by this water extraction will creat a pressure differetial that will allow water to migrate from other areas to fillup the void spaces created by the water being extracted and then also God has blessed us with plenty of Rains even in the Abuja and Kaduna area. This has ensured a continuous recharge of the acquifers either directly by infiltration or rise in water table occasioned by rise in River levels. So I Particularly find it disturbing that an agency such as that will put a major blame on bore Hole activities. And as for the Mpape area where there are quarries for granitic materials used for construction, the quarrying activities may have created an inbalance especially as there is a strike -slip fault passing below the area which could be respeonsible for tremors. By and large major Earth quakes are not expected in Nigeria. What we may have are low magnitude Earth-quakes or Tremors. Now what is your take? 2 Likes 1 Share |

We've never been ready for anything as nation.So,I'd like to see how we respond to the possibility of these seismi eruptions. |

Icon4s: Not sure I agree with your point on water from other part of aquifer migrating to an aquifer zone that water is being drawn from. Yes, we know that aquifer water also move by convection or other forms of transport from one point to another but when rate of water extraction exceed the rate of replenishment then the level of water table drops below original level leaving interstitial air-filled pore spaces that are devoid of water. That's the kind of situation the agency is referring to. It's not new. Sane way excessive oil extraction is linked to earthquakes in certain parts of the world. Let's use this analogy. Which is going to be easier to press down from top by compaction? A square shape sponge that is water soaked or same type of sponge with lot more air spaces? In a earthquake situation, I am assuming that seismic wave velocity will be faster in rocks with lot of air-spaces than in rocks that is fully saturated with water. Hope that make sense when you think of seismic waves from earthquake or earth tremors epicentre and how it affects areas that are far from the epicenter. |
Re: Major Earthquake Likely In Abuja, Kaduna, Ogun, Oyo, Bayelsa – NASRDA by Icon4s(m): 11:45am On Sep 28, 2018 |
ajl:. Firstly, if you go through my statement again you will see where I said it is possible but not likely. The report hinged more on Bore Hole Drilling as being the cause of the Tremors. Which I am not buying into. My opinion is it could be but chances are slim. Then, I see your analogy and so let us pick them one after the other. -How does the interstitial spaces in the rocks become air filled and devoid of water. Where is the air from? -And yes rate of water extraction can exceed rate of replenishment within the immediate locality and this is typical of the Dry season. But the Mpape incident took place at the peak of rainy season when water levels are highest. Remember also that water travels fast so the water level that was depleted in the last dry season has long been replenished. -And the second bolded which is a case of Earth quake due to Oil extraction. This is a very rare phenomenon even though it has happened in the past. What happens during Oil production? As the Oil leaves the reservoir the drive mechanism takes over and fill up the spaces left by the migrating Oil. This mechanism can be Water or the Gas Cap. This is a process called water coning and or Gas Cap expansion. No void or vacuum is left. So that analogy of empty Air space does not work here. -Then finally on your last bolded, let me assume the presence of air space in Rock layers as deep as 100-200ft which you have opined. One of the factors that affect the velocity of travel of waves in a medium is what? Bulk Density of the medium. What is Bulk density? Density of the rock matrix and the fluid content. So between a water baring rock and Air bearing rock which should have a higher Bulk Density? Water bearing Rock because water is more dense than Air. As Velocity is directly proportional to bulk density it simply implies that seismic waves have higher velocities in water bearing rocks than in Air bearing rocks. (hint; Speed of sound in Air=340m/s, speed of sound in water=1481m/s). Now over all get my point once again. Though it is possible for Bore Hole sinking to be responsible for the Tremors, it may not be the more likely reason. The natural tectonic setting IMHO may have more role to play than Bore Hole drilling. The Mpape incident could have been caused by disequilibrium created due to mining in the area and assisted by the strike-slip faults that run through the area. And not bore Holes. I would recommend an intensive, Geological investigation using the latest technology for much of our Basement Complex areas, expecially areas that have received these Tremors in the recent past (ie last 100 years). I will like to see your response. 1 Like |

110,000 boreholes yielding 330,000MT of water daily. That breaks down to 3MT or 3,000 cubic meters or 3,000,000 liters of water per borehole. Very suspicious data. 1 Like |
