Methodology
Understand what the catalogue includes, how places are assigned and how source corrections reach this website.
Data sources
The historical archive includes USGS M6+ events from 1900, M4.5+ from 1970 and observations retained since 29 October 2026. The recent 90-day window additionally imports available smaller events. Thresholds follow the source’s preferred magnitude. Small-event detection and historical coverage are uneven; a zero count is not proof that no earthquake occurred.
Understand these data
Country membership uses the reported epicentre and Natural Earth polygons. An offshore reference country is separate from a position inside a country. GeoNames supplies reference settlements and attested names. Distances are approximate geographic context. Place searches offer 25, 50, 100 or 250 km radii; historical map days use UTC, while local-day views name their time zone.
Source revision
Stable UUIDs preserve event links when measurements change. Original source identifiers and revisions remain distinguishable. Trusted exact identities may refer to the same event; proximity alone does not merge records or prove an aftershock. Withdrawn or reclassified reports are removed from active lists. Update times identify the available publication, not a guarantee of instant delivery.
