Common Questions

What people usually ask about a notice like this one.

What magnitude was this earthquake? ▾
A magnitude 3.1 ml earthquake struck 59 km WNW of Aleneva, Alaska at a depth of 66.7 km.
How should a magnitude 3.1 ("Minor") event be understood? ▾
The USGS classifies M3.1 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 #1,530 strongest of the 1,782 earthquake reports in Areazine's archive by magnitude, stronger than 8% of them and weaker than 1,529 others.
Was Aleneva likely to feel this earthquake? ▾
This event was centered 59 km WNW of Aleneva. 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.
