The Nigerian Geological Survey Agency (NGSA) says there is no need for residents of the federal capital territory (FCT) to panic over recent earth tremors.
Residents of Mpape and Katampe communities in the FCT recently expressed fears following earth tremors that reportedly began on Saturday.
An earth tremor is a relatively small or short-lived movement of the earth’s surface. It is caused by the same forces that produce earthquakes.
In a statement on Wednesday, Olusegun Ige, NGSA director-general, said the agency monitored the tremors and found them to be low.
He added that the tremors do not pose any threats.
“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,” the statement reads.
“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.
“More than twenty events were recorded on the 16th of September. The intensity and frequency of the tremor appear to increase from the 13th to 16th September. There are a few weak events recorded today, 17th September.
“Preliminary analysis of the waveforms showed that the sources of the ground motions are less than 5 km away from the monitoring station.
“NGSA team also 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, the following conclusions were made:
“The tremors are a result of accumulated stress along the identified faults and released seismic energy, which may have traveled through associated fractures to areas where the tremors were felt around the FCT.
“There are multiple epicenters associated with the recent tremor. Most of the epicenters are located northeast of the NGSA-5 Seismic Station around Mpape axis, while a few are located southwest of the Station around 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 agency added that it is closely monitoring the situation.
“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 statement adds.
“The Agency is keeping a close monitoring of the situation and will provide updates as may become necessary.
“The general public should also be aware that the NGSA Seismic Stations are being monitored in real time to ensure prompt alerts on any major event.”
