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
