The Sierra Leone Institution of Geoscientists (SLIG) has called for a scientific investigation into reports of earth tremors in parts of Freetown, urging residents to remain calm and avoid spreading unverified claims about a possible major earthquake.
In an advisory issued on Wednesday, the institution said reports of shaking had been received from several locations in central Freetown, including the Youyi Building, on Monday, October 13. The reports coincided with a magnitude 6.9 earthquake recorded along the Central Mid-Atlantic Ridge at approximately 12:23 UTC.
However, SLIG said the available information did not establish a direct link between the offshore earthquake and the reported tremors in Freetown. It stressed that further scientific assessment was needed to determine the cause, extent and potential effects of the reported shaking.
The institution cautioned against speculation about an imminent major earthquake, noting that current scientific methods cannot precisely predict the exact time, location and magnitude of an earthquake.
To establish what occurred, SLIG called for cooperation among government agencies, emergency responders, research institutions and other relevant stakeholders. It recommended reviewing international seismic records, available monitoring data and eyewitness accounts from affected areas.
The institution also highlighted the need to strengthen earthquake monitoring systems, improve geological hazard assessments and increase public awareness of seismic risks. It further called for earthquake hazards to be considered in infrastructure planning and development.
As part of its safety advice, SLIG urged residents to follow established protective measures if they experience shaking. These include dropping to their hands and knees, taking cover under sturdy furniture where available, protecting their heads and necks, and staying away from windows and objects that could fall.
After the shaking stops, residents should check for injuries, avoid entering damaged buildings and report emergencies or suspected structural damage to the relevant authorities.
SLIG also encouraged people who experienced the reported tremors to provide information about the approximate time, duration and location of the shaking, as well as any observed effects. Such details could help experts assess the reports and determine what happened.
The institution maintained that the information it had reviewed provided no scientific basis for declaring that a major earthquake was imminent near Sierra Leone. It nevertheless emphasised the importance of continued investigation, reliable public communication and preparedness in reducing risks associated with seismic activity.
