NIGERIAN GEOLOGICAL SURVEY AGENCY ALLAYS FEARS OVER TREMORS IN ABUJA, SAYS IT IS LOW LEVEL THREAT 

The Director-General of the Nigerian Geological Survey Agency (NGSA), has revealed that the Agency had closely monitored the recent tremors in the Federal Capital Territory and observed that it was low level, consequently posing no significant thereat.

In a statement released on Wednesday by the Agency, Prof. Olusegun Ige, Director-General of the NGSA, disclosed that the Agency had closely monitored the seismic activity and confirmed that the tremors were low in magnitude.

He emphasised that there was no evidence to suggest that the tremors posed any significant threat to the safety of the environment or its inhabitants.

The statement read, “The Monitoring Station (NGSA-5) at Katampe has been capturing several significant ground motions with high moment magnitudes (Mw) in the past five days, beginning from September 13, 2024, till date. Only one mild event was recorded on September 13th. Six of these events were captured on the 14th of September, while over 21 events were captured on the 15th with higher intensities."

Ige explained that more than 20 events were recorded on the 16th of September.

The intensity and frequency of the tremor appear to increase from the 13th to 16th of September.

He noted that, preliminary analysis of the waveforms showed that the sources of the ground motions were less than 5 km away from the monitoring station.

Ige added that his team visited the affected areas for on-the-spot assessments of the events.

From the accounts of the residents of the affected areas, the observations by the NGSA team, and findings from earlier interpretations of the airborne geophysical data over the area and adjoining areas, it said the following conclusions were made:

He said the tremors are a result of accumulated stress along the identified faults and released seismic energy, which may have travelled through associated fractures to areas where the tremors were felt around the FCT.

"There are multiple epicentres associated with the recent tremor. Most of the epicentres are located northeast of the NGSA-5 Seismic Station around the Mpape axis, while a few are located southwest of the Station around the Katampe axis.

"The intensities of the tremors are weak to light, ranging from III-IV on the Modified Mercalli Scale, and pose a very low level threat.

"The residents of Mpape, Katampe, Maitama, and other areas where the tremors were felt are advised not to panic as the tremors can be generally described as low. The agency is keeping a close monitoring of the situation and will provide updates as may become necessary."

He added that the general public be in the know, that the NGSA Seismic Stations are being monitored in real-time to ensure prompt alerts on any major event.
