Top 12 countries by m6+ events

Countries ranked by number of significant (M6+) earthquakes catalogued.

Value

What this shows Significant (M6+) earthquakes are the ones that cause real damage. Countries topping this list combine high seismic activity with proximity to subduction zones. The count reflects how often a country faces genuinely dangerous shaking, not just how many small tremors it records.

Frequently asked questions

What makes an earthquake significant here?

On PlainQuake, "significant" means magnitude 6.0 and above, the threshold at which structural damage becomes likely in populated areas.

Why do some countries with fewer total earthquakes rank high here?

Because this counts only the damaging M6+ band. A country can record many small tremors but few large ones, or vice-versa, depending on its tectonic setting.

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.
