Ghana is not located in an earthquake-prone area but it has had its fair share of earthquakes and tremors over the years. The history of recorded earthquakes and tremors in Ghana date as far back as 1615. Most of the earthquakes and tremors have been around the magnitude of 4 on the Richter scale. Earthquakes and tremors that normally cause damage to property have a magnitude of 5.5 and upwards.

History of Earthquakes and Tremors in Ghana

Information was gathered from a research publication and a news article.

The most recent earth tremor was recorded on 24 June, 2020 at 10:53 pm just 7 km from Gbawe. But it was felt in Accra and some parts of Cape Coast. You can report what you felt to help gather information on the event.

Building Earthquake Resistant Buildings

When earthquakes or earth tremors strike, the most damaged structures are normally buildings. Real estate developers should have their buildings retrofitted to withstand earthquakes and tremors. There are two major fault zones in Ghana at Akwapim and the coastal boundary. These areas are prone to seismic activity so it is advisable to build highly earthquake-resistant buildings within these areas. Developers are advised to perform a geotechnical evaluation on their properties.

This will provide information on the physical properties of soil, earthworks and foundations for structures to help identify and repair distress to earthworks and structures caused by subsurface conditions.

Earthquakes are natural phenomena we don’t have much control over but we can take some measures, such as those listed above, to help reduce the damage caused by earthquakes in Ghana and thereby preserve and protect lives and property or real estate.
