Earthquakes in Zambia

Zambia has catalogued 62 M4+ earthquakes since 2005 (ranked 95th of 187 countries), with the strongest reaching magnitude M6.5.

Zambia ranks 95th of 187 countries by catalogued seismic activity - a country with limited but non-zero seismic activity, averaging about 3 M4+ events a year alongside 2 significant M6+ earthquakes since 1900. The M6+ record here is thin - 2 events in all, so a single quake moves every figure on this page.

Frequently asked questions

How many earthquakes have occurred in Zambia?
The USGS catalog records 62 earthquakes of magnitude 4.0 or greater in Zambia since 2005, an average of about 3 per year. Separately, 2 significant (M6+) earthquakes are catalogued back to 1900.
What was the strongest earthquake in Zambia?
The strongest catalogued earthquake in Zambia measured magnitude 6.5. Across the full M4+ catalog the average magnitude is 4.5 - most earthquakes are moderate.
How seismically active is Zambia?
By catalogued M4+ activity, Zambia ranks 95th of 187 countries worldwide - a country with limited but non-zero seismic activity. Its busiest year for major (M6+) events was 1919, with 1.
How deep are earthquakes in Zambia?
Across the 2 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 Zambia's numbers mean

Zambia ranks 95th of 187 countries tracked - a country with limited but non-zero seismic activity.

  • About 3 M4+ earthquakes strike Zambia per year on average, though major (M6+) activity is episodic - 1919 was the busiest year on record with 1 significant events. See the full country ranking
  • 100% of Zambia'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 M6.5. Compare against neighboring or similarly-ranked countries before drawing conclusions from magnitude alone. Compare strongest earthquakes
