Earthquakes in Federated States of Micronesia

Federated States of Micronesia has catalogued 59 M4+ earthquakes since 2005 (ranked 96th of 187 countries), with the strongest reaching magnitude M7.8.

Federated States of Micronesia ranks 96th of 187 countries by catalogued seismic activity - a country with limited but non-zero seismic activity, averaging about 3 M4+ events a year alongside 8 significant M6+ earthquakes since 1900. Severity outweighs frequency here: 25% of its M6+ record sits at M7 or above.
