dans le temps.
Choose a date range and minimum magnitude. See the global count, monthly trend and strongest events in the sample.
The chart displays at most 2,000 events; the untruncated total is queried separately.
The historical explorer is ready.
Choose a period and query the catalogue. Years of data are not loaded until you ask for them.

05 · How to read SeismoTotal
Données réelles.
Limites visibles.
The map reads official USGS GeoJSON feeds and refreshes every five minutes.
The explorer uses the USGS FDSN service. The total is not truncated; the chart caps its sample to keep the site responsive.
The Poisson model extrapolates a past rate. It explores frequency; it does not forecast when an earthquake will happen.
For construction, insurance or emergency planning, use geological studies, official maps, local codes and qualified professionals.
