Earthquakes in Spain

Spain has catalogued 88 M4+ earthquakes since 2005 (ranked 83rd of 187 countries), with the strongest reaching magnitude M6.4.

Spain ranks 83rd of 187 countries by catalogued seismic activity - a country with limited but non-zero seismic activity, averaging about 4 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.

The verdict

Spain is moderately seismically active, above the global median, with 88 M4+ earthquakes logged since 2005 and 2 major M6+ events since 1900, the strongest reaching magnitude 6.4.

Average catalogued magnitude is 4.3 - most events are moderate M4-5 tremors that are felt but rarely cause damage. On the M4+ activity ladder Eritrea sits immediately above at 93 events and Palau sits immediately below at 84.

Where Spain sits in the catalog

Rank 83rd of 187 tracked countries (55th percentile by M4+ count since 2005). On the M4+ activity ladder Eritrea sits immediately above at 93 events and Palau sits immediately below at 84.

  • Eritrea - next more active (93 M4+)
  • Palau - next less active (84 M4+)

Same M4+ count, broken by peak magnitude

2 tracked countries share Spain's exact count of 88 M4+ events since 2005. Among that cohort, Spain ranks 1st of 2 by strongest recorded magnitude (M6.3).

Frequently asked questions

How many earthquakes have occurred in Spain?
The USGS catalog records 88 earthquakes of magnitude 4.0 or greater in Spain since 2005, an average of about 4 per year. Separately, 2 significant (M6+) earthquakes are catalogued back to 1900.
What was the strongest earthquake in Spain?
The strongest catalogued earthquake in Spain measured magnitude 6.4. Across the full M4+ catalog the average magnitude is 4.3 - most earthquakes are moderate.
How seismically active is Spain?
By catalogued M4+ activity, Spain ranks 83rd of 187 countries worldwide - a country with limited but non-zero seismic activity. Its busiest year for major (M6+) events was 1910, with 1.
How deep are earthquakes in Spain?
Across the 2 major (M6+) events on record, the average depth is 312 km. 50% 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 Spain's numbers mean

Spain ranks 83rd of 187 countries tracked - a country with limited but non-zero seismic activity.

  • About 4 M4+ earthquakes strike Spain per year on average, though major (M6+) activity is episodic - 1910 was the busiest year on record with 1 significant events. See the full country ranking
  • 50% of Spain'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
