‘Ge­o­log­i­cal knowl­edge re­quired to avert earth­quake in Nige­ria’

THE Min­is­ter of Mines and Steel De­vel­op­ment, Olamilekan Adeg­bite, has said that there is a need for Nige­ri­ans to have knowl­edge of the na­tion’s ge­o­log­i­cal make-up in or­der to avert tre­mors and earth­quake.

He said this in Ibadan, the Oyo State cap­i­tal, dur­ing the 2019 Nige­rian Min­ing and Geo­science So­ci­ety and Nige­ria Ge­o­log­i­cal Sur­vey Agency Dis­course Se­ries on Earth Tre­mors in Nige­ria and the Role of Geo­sci­en­tist.

The Min­is­ter said that the re­cent se­ries of crustal dis­tur­bance which were ex­pe­ri­enced in Mpape, Katampe, Maitama and Gwarimpa, all in Abuja on the 5th to 7th Septem­ber and 2nd of Novem­ber, 2018 had no doubt sug­gested that Nige­ria could no longer be con­sid­ered to be in seis­mi­cally sta­ble re­gion of the world.

Adeg­bite who was rep­re­sented by a di­rec­tor in the min­istry, Davies Ola­pade, stated that there was a need to have knowl­edge of the ge­ol­ogy of Nige­ria and the origin of earth­quake.

He said, “Nige­ri­ans need to have clear un­der­stand­ing of the dis­as­ters. Study has shown that earthquake­s are waves of dis­tur­bance that are re­leased when a rock mass un­der stress rup­tures.”

The min­is­ter added that the earth tre­mor oc­cur­rence in Nige­ria had been re­ported in dif­fer­ent parts of the coun­try and it dated back to 1933.

He, how­ever, noted that the seis­mic event of July 28, 1984 which were no­tice­able around Ijebu-ode, which trig­gered a very sig­nif­i­cant in­ter­est in earth tre­mor.

He said, “Nige­ria lies within the in­traplate tec­tonic zone, the seis­mic ac­tiv­i­ties in such zone are ei­ther nat­u­ral like long ac­tive fault zones or hu­man-in­duced, be­cause Nige­ria is known to have ac­tive fault lines which are well pro­nounced in the air­borne mag­netic maps.

“Seis­mic­ity like earth tre­mor we are ex­pe­ri­enc­ing now could be hu­man- in­duced through hu­man ac­tiv­i­ties like blast­ing of quar­ries in sourc­ing for con­struc­tion ag­gre­gate ma­te­ri­als and ground wa­ter ex­trac­tions through bore holes.
