M6.3

M 6.3 - Bering Sea

Strong Earthquake · May 1, 2010 · Bering Sea

Key Insights

•This M6.3 strong earthquake ranks #108 out of 470 events in the database.
•At M6.3, this is 0.6 points above the database average of M5.7. Each whole magnitude point represents roughly 32x more energy released.
•At 14.9 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 611 places this among the 265 most impactful events tracked, based on magnitude, felt reports, and damage potential.

Frequently Asked Questions

How strong was the Bering Sea earthquake?

The Bering Sea earthquake had a magnitude of 6.3 mwc, classified as a "Strong" earthquake on the magnitude scale. Earthquakes of this size can cause serious damage to buildings and infrastructure over a wide area.

Where exactly did this earthquake occur and how deep was it?

This earthquake struck at coordinates 60.4780N, 177.6500W, at a depth of 14.9 km. Shallow earthquakes (under 20 km) tend to cause more surface damage than deeper events.

Did this earthquake trigger a tsunami warning?

No tsunami warning was issued for this earthquake. Earthquakes below magnitude 6.5 rarely generate dangerous tsunamis, though localized effects are possible in rare cases.

How many people felt this earthquake?

No felt reports were submitted to the USGS for this earthquake. This may indicate the earthquake occurred in a remote area with few nearby residents, or the shaking was too minor to be widely noticed.

When did this earthquake happen and how significant was it?

This earthquake occurred on May 1, 2010 at 08:16:28. The USGS assigned it a significance score of 611 out of a possible 3,000, which factors in magnitude, felt reports, and potential impact. This is a moderately significant seismic event.
