A senior seismologist at the Geological Survey Authority (GSA), Nicholas Opoku, has revealed that per his outfit’s observations, there is an earthquake bound to happen in Accra following the earth tremor of March 2, 2019.
Speaking on the radio show Atinka AM Drive, the seismologist stated that earthquakes do not happen in a vacuum. He noted that looming earthquakes usually give caution which usually manifest in tremors.
The March 2 tremor measured 3.9 on Richter scale and was experienced in such places as Gbawe, Sowutuom, Old Kasoa Barrier, New Bortianor, Awoshie, Abelemkpe and McCarthy Hill.
A similar earth tremor occurred in late December 2018 around Weija and Gbawe in the Ga South municipality.
According to Opoku, these frequent tremors are indications that fault lines are active. A good amount of Accra has already been identified as geological fault lines.
Opoku noted that: “For instance, the earthquake that occurred in the 1980s, gave warning signals ahead for about 40 years before it finally occurred.”
He, however, expressed worry over the fact that the GSA currently has only one Seismology station located near the Ghana Institute of Management and Public Administration (GIMPA) in Accra.
He used the opportunity to plead for government’s investment into helping track and monitor these incidents.
Ghana has not had any major earthquake since 1939 but it is an area prone to earth tremors, some of which have been described as minor earthquakes.
