Une année de séismes forts
Chaque pointe est un séisme de magnitude 5,5 ou plus des douze derniers mois (USGS ComCat) ; sa hauteur suit la magnitude, sa couleur la profondeur. Les anneaux signalent les plus forts. Les séismes dessinent les limites des plaques.
- < 70 km (superficiel)
- 70–300 km (intermédiaire)
- > 300 km (profond)

Le catalogue USGS ComCat (ANSS) est lu par le service web FDSN, une requête par année civile depuis 1900 pour les magnitudes ≥ 4,5 ; les deux dernières années sont relues à chaque mise à jour car les solutions sont révisées. Les magnitudes sont celles publiées (mb, Ms, Mw, ml…) et ne sont pas converties ; la profondeur est celle de l’hypocentre en km.
Les comptes annuels sont calculés sur le serveur à partir des événements importés de type « earthquake » (les explosions et autres types sont conservés mais exclus des comptes). Les séismes historiques et leurs bilans viennent de la base NCEI/WDS des séismes significatifs, datés à l’année quand le jour est inconnu.
