Frequently asked questions

What is the strongest earthquake ever recorded?

The M9.5 1960 Valdivia earthquake in Chile, the largest ever recorded by modern instruments. It ruptured roughly 1,000 km of fault and generated a Pacific-wide tsunami.

Can earthquakes exceed magnitude 10?

It is theoretically possible but extraordinarily unlikely, an M10 would require a fault rupture longer than any known fault (~10,000 km). The scale is logarithmic: M10 releases about 32× the energy of M9.5.

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.
