Frequently asked questions

How many earthquakes have occurred in Federated States of Micronesia?
The USGS catalog records 59 earthquakes of magnitude 4.0 or greater in Federated States of Micronesia since 2005, an average of about 3 per year. Separately, 8 significant (M6+) earthquakes are catalogued back to 1900.
What was the strongest earthquake in Federated States of Micronesia?
The strongest catalogued earthquake in Federated States of Micronesia measured magnitude 7.8. Across the full M4+ catalog the average magnitude is 4.8 - most earthquakes are moderate.
How seismically active is Federated States of Micronesia?
By catalogued M4+ activity, Federated States of Micronesia ranks 96th of 187 countries worldwide - a country with limited but non-zero seismic activity. Its busiest year for major (M6+) events was 2014, with 2.
How deep are earthquakes in Federated States of Micronesia?
Across the 8 major (M6+) events on record, the average depth is 20 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 Federated States of Micronesia's numbers mean

Federated States of Micronesia ranks 96th of 187 countries tracked - a country with limited but non-zero seismic activity.

  • About 3 M4+ earthquakes strike Federated States of Micronesia per year on average, though major (M6+) activity is episodic - 2014 was the busiest year on record with 2 significant events. See the full country ranking
  • 100% of Federated States of Micronesia'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 M7.8. Compare against neighboring or similarly-ranked countries before drawing conclusions from magnitude alone. Compare strongest earthquakes
