Earthquakes in Ghana

Ghana has catalogued 1 M4+ earthquakes since 2005 (ranked 173rd of 187 countries), with the strongest reaching magnitude M6.4.

Ghana ranks 173rd of 187 countries by catalogued seismic activity - a country with limited but non-zero seismic activity, averaging about 0 M4+ events a year alongside 1 significant M6+ earthquakes since 1900. The M6+ record here is a single event, so one quake sets every figure on this page.

Frequently asked questions

How many earthquakes have occurred in Ghana?
The USGS catalog records 1 earthquakes of magnitude 4.0 or greater in Ghana since 2005, an average of about 0 per year. Separately, 1 significant (M6+) earthquakes are catalogued back to 1900.
What was the strongest earthquake in Ghana?
The strongest catalogued earthquake in Ghana measured magnitude 6.4. Across the full M4+ catalog the average magnitude is 4.0 - most earthquakes are moderate.
How seismically active is Ghana?
By catalogued M4+ activity, Ghana ranks 173rd of 187 countries worldwide - a country with limited but non-zero seismic activity. Its busiest year for major (M6+) events was 1939, with 1.
How deep are earthquakes in Ghana?
Across the 1 major (M6+) events on record, the average depth is 15 km. 100% were shallow (under 70 km), where surface shaking is strongest at a given magnitude.
Where does this data come from?
Every figure is derived from the USGS Comprehensive Earthquake Catalog (ComCat). M4+ counts cover 2005 onward (the period of consistent global completeness); the significant-event series covers M6+ back to 1900. Nothing is modelled or estimated.

What Ghana's numbers mean

Ghana ranks 173rd of 187 countries tracked - a country with limited but non-zero seismic activity.

  • About 0 M4+ earthquakes strike Ghana per year on average, though major (M6+) activity is episodic - 1939 was the busiest year on record with 1 significant events. See the full country ranking
  • 100% of Ghana's catalogued major earthquakes are shallow (under 70km) - shallow events generally produce stronger surface shaking than deep ones of the same magnitude. How depth affects shaking
  • The strongest catalogued event reached M6.4. Compare against neighboring or similarly-ranked countries before drawing conclusions from magnitude alone. Compare strongest earthquakes
