How we check forecasts

All our current forecasts, with the period each one covers and the report it is based on.

Important: These are our own estimates, not official warnings. We do not predict exactly when an earthquake will strike. We check each forecast only against real harm or damage, reported by an independent source after the forecast was made.

How we check a forecast

Timing
The harm or damage must happen during the forecast period.
Place
It must happen in the area we named when we recorded the forecast.
Cause
The hazard must happen in the way we forecast.
Real harm
A warning or report that already existed does not count as a correct forecast on its own. The harm or damage must be reported by an independent source, and it must be serious enough to matter.
Result
We mark each forecast correct, partly correct, wrong or cannot be checked. We keep the evidence from our sources.
