The verdict
Guinea is relatively quiet seismically compared to most places tracked here, with 8 M4+ earthquakes logged since 2005 and 1 major M6+ events since 1900, the strongest reaching magnitude 6.3.
- 1983
- busiest year (1 major events)
- 11 km
- average recorded event depth
- 100%
- of events are shallow (<70 km, the most damaging kind)
Average catalogued magnitude is 4.5 - most events are moderate M4-5 tremors that are felt but rarely cause damage. On the M4+ activity ladder Germany sits immediately above at 9 events and Hungary sits immediately below at 7.
Where Guinea sits in the catalog
Rank 146th of 187 tracked countries (21th percentile by M4+ count since 2005). On the M4+ activity ladder Germany sits immediately above at 9 events and Hungary sits immediately below at 7.
Same M4+ count, broken by peak magnitude
2 tracked countries share Guinea's exact count of 8 M4+ events since 2005. Among that cohort, Guinea ranks 1st of 2 by strongest recorded magnitude (M5.0).
| Country | M4+ count | Strongest |
|---|---|---|
| Guinea (this page) | 8 | M5.0 |
| French Polynesia | 8 | M4.8 |
0 of 8 catalogued M4+ events since 2005 reached M6.0 or higher.

What Guinea's numbers mean
Guinea ranks 146th of 187 countries tracked - a country with limited but non-zero seismic activity.
- About 0 M4+ earthquakes strike Guinea per year on average, though major (M6+) activity is episodic - 1983 was the busiest year on record with 1 significant events. See the full country ranking
- 100% of Guinea'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 M6.3. Compare against neighboring or similarly-ranked countries before drawing conclusions from magnitude alone. Compare strongest earthquakes
