Ghanaians must prepare for a possible earthquake strike – Dr. Ahulu

Ghana must position itself through enforcement of its own codes and standards to deal with any destructive earthquake strike in the future in order not to be taken by surprise.

Accra, the nation’s capital lies on a fault-line and there is regular seismic activity in the country.

The combined effect of rapid development, industrialization, building of houses and roads, vehicular movement and even fufu pounding amongst others is leading to the grounds beneath us moving very rapidly.

This has the potential of triggering massive earthquakes which can be devastating if the quality of our buildings is not checked to make them earthquake resilient.

Dr. Sylvanus Tetteh Ahulu, an Associate of MaxConsolidated Lawyers and Architects and also former Head of Seismology & Earthquake Engineering Division at the Ghana Geological Survey Authority, said earthquakes by themselves don’t kill but weak structural elements which cannot withstand the strength of the vigorous shaking can lead to death.

This is especially so when they disintegrate and fall on people during the cause of a tremor or heavy shaking. Parts of Accra and its environs were struck by earth tremors in April, 2020 and there are expectations that there could be devastating ones in the future.

“There is still an alarming expectation of another destructive earthquake following this one in the very foreseeable future. This brings to bear the need for the country to position itself in addressing such an eventuality. It is not worthwhile for anybody to be taken by surprise,” .

A report, after the 1939 destructive earthquake in Ghana, stated that buildings in Accra in particular should not go up vertically beyond two storeys because of the inconsistent geology of Accra and the fact that Accra’s soil profile cannot withstand earthquakes with a high rise building regime.

However, with rapid urbanization, engineering solutions and population growth, buildings more than two storeys are springing up within the city.

“It is really worrying that these structures are right in the Centre of a well-known seismic zone. This therefore makes those buildings vulnerable to the disastrous seismic effect,”.
