Frequently asked questions

How many earthquakes have occurred in Republic of the Congo?
The USGS catalog records 1 earthquakes of magnitude 4.0 or greater in Republic of the Congo since 2005, an average of about 0 per year. Separately, 0 significant (M6+) earthquakes are catalogued back to 1900.
What was the strongest earthquake in Republic of the Congo?
The strongest catalogued earthquake in Republic of the Congo measured magnitude 4.2. Across the full M4+ catalog the average magnitude is 4.2 - most earthquakes are moderate.
How seismically active is Republic of the Congo?

How deep are earthquakes in Republic of the Congo?
Across the 0 major (M6+) events on record, the average depth is N/A km. 0% 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.
