Frequently asked questions

Does a high average magnitude mean more danger?

Not necessarily. A high average can simply mean only large events are detected due to sparse monitoring. The metric compares tectonic environments, not absolute risk.

Why the minimum-event filter?

A single large event would give a misleadingly high average. Requiring at least 10 catalogued events makes the figure statistically meaningful.

About this data

These rankings are computed directly from the USGS Comprehensive Earthquake Catalog (ComCat), the public-domain record maintained by the USGS Earthquake Hazards Program. Count-based leaderboards use the worldwide catalog of magnitude-4.0-and-above events from 2005 onward, the period over which the global seismograph network reliably detects and locates earthquakes everywhere, while magnitude leaderboards use the significant-event series of magnitude-6.0-and-above earthquakes stretching back to 1900. Magnitudes use the moment-magnitude scale (Mw), the modern standard that supersedes the older Richter scale; because the scale is logarithmic, each whole step up represents roughly thirty-two times more energy released. Remember that raw counts partly measure monitoring density, not only underlying seismicity, and that one historic outlier can anchor a high maximum magnitude, read each leaderboard alongside population exposure and building stock before drawing conclusions about real-world risk.
