Frequently asked questions

How many earthquakes have occurred in Chad?
The USGS catalog records 2 earthquakes of magnitude 4.0 or greater in Chad 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 Chad?
The strongest catalogued earthquake in Chad measured magnitude 4.4. Across the full M4+ catalog the average magnitude is 4.4 - most earthquakes are moderate.
How seismically active is Chad?
By catalogued M4+ activity, Chad ranks 166th of 187 countries worldwide - a country with limited but non-zero seismic activity.
How deep are earthquakes in Chad?
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.

What Chad's numbers mean

Chad ranks 166th of 187 countries tracked - a country with limited but non-zero seismic activity.

  • About 0 M4+ earthquakes strike Chad per year on average. See the full country ranking
  • 0% of Chad'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 M4.4. Compare against neighboring or similarly-ranked countries before drawing conclusions from magnitude alone. Compare strongest earthquakes
