03 · Historical catalogue

Travel back
in time.

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.

04 · Local statistics

Place a point.
Read its history.

Calculate the frequency of recorded earthquakes within a radius and the mathematical probability of at least one event in a future horizon, assuming the historical rate remains stable.

Coordinates

One-time search with OpenStreetMap/Nominatim. It does not run while you type.

Examples:
This is not an earthquake prediction. It is a descriptive statistical extrapolation. It does not replace official hazard maps, fault studies, geotechnics or building codes.

Your point is still empty.

Enter coordinates or try an example. The calculation only runs when you press the button.

05 · How to read SeismoTotal

Real data.
Visible limits.

Live

The map reads official USGS GeoJSON feeds and refreshes every five minutes.

History

The explorer uses the USGS FDSN service. The total is not truncated; the chart caps its sample to keep the site responsive.

Estimate

The Poisson model extrapolates a past rate. It explores frequency; it does not forecast when an earthquake will happen.

Actual hazard

For construction, insurance or emergency planning, use geological studies, official maps, local codes and qualified professionals.
