Common Questions

Common questions about this USGS earthquake report.

What magnitude was this earthquake? ▾
A magnitude 3.2 earthquake occurred 57 km ENE of Chenega, Alaska, at a depth of 16 km.
What does a magnitude 3.2 ("Minor") earthquake mean? ▾
The USGS classifies M3.2 as "Minor" on its Earthquake Hazards Program scale. Events in this range are rarely felt beyond the immediate epicenter and typically cause no damage; most are recorded only by seismographs.
Where does this event rank against Areazine's other recorded earthquakes? ▾
This is the #1,380 strongest of the 1,740 earthquake reports in Areazine's archive by magnitude, stronger than 14% of them and weaker than 1,379 others.
Was Chenega likely to feel this earthquake? ▾
This event was centered 57 km ENE of Chenega. Shaking intensity falls off sharply with distance from the epicenter and depends on depth and local geology, so check the USGS "Did You Feel It?" report for this event for real felt-shaking data rather than assuming from magnitude and distance alone.
