GLOBAL SEISMIC CATALOG / ICDO MEMBER STATE REPORTS
Earthquake Activity
Instrumental earthquake observations from USGS and EMSC/FDSN, with a separate view of reported incidents in ICDO Member States.
The seismic catalog covers the whole world, not only ICDO Member States. Magnitudes and epicentres are from USGS/EMSC. Country-specific incident reports are a separate source and are not counted as instrumental observations.
01 / INSTRUMENTAL SEISMICITY · WORLDWIDE
Earthquake epicentres
Recent USGS/EMSC locations, symbolized by actual magnitude.
Showing 1000 prioritized epicentres from 3626 global observations. USGS and EMSC detections are deduplicated using conservative time, location and magnitude matching; some uncertain matches remain separate.
02 / GLOBAL SEISMIC CATALOG
Strongest observed earthquakes
Highest magnitudes in the selected period · USGS / EMSC.
03 / ICDO MEMBER STATES · INCIDENT REPORTS
Reported impacts
Distinct source-reported incidents; not matched to seismic observations.
03 / GLOBAL OBSERVATION FREQUENCY
Earthquakes by UTC day
Daily counts include only seismic events with a recorded magnitude and valid epicentre. They describe observed activity, not reported humanitarian impact.
04 / MEMBER STATE INCIDENT REPORTING
Source reports by Member State
These are incident registry reports, not counts of earthquakes located within each country's boundaries. Unmatched country labels are excluded.
