Strong Earthquake · October 22, 2010 · 97 km SSW of El Huitusi, Mexico

Key Insights

•This M6.7 event ranks #40 of 470 earthquakes by magnitude, stronger than 91% of recorded US events.
•At M6.7, this is 1 points above the database average of M5.7. Each whole magnitude point represents roughly 32x more energy released.
•At 13.0 km depth, this is classified as a shallow earthquake. Shallow quakes typically cause stronger ground shaking and more damage than deeper events (avg depth: 27 km).
•A USGS significance score of 776 places this among the 265 most impactful events tracked, based on magnitude, felt reports, and damage potential.
