Frequently Asked Questions

What people usually ask about a notice like this one.

What was the magnitude of this event?
A magnitude 3.8 earthquake occurred 95 km SSW of Nikolski, Alaska, at a depth of 24.9 km.
What does an M3.8 "Minor" reading actually indicate?
The USGS classifies M3.8 as "Minor" on its Earthquake Hazards Program scale. Events in this range are often felt near the epicenter and can cause minor damage to vulnerable structures, though widespread damage is uncommon.
Is this earthquake stronger or weaker than others in the archive?
This is the #980 strongest of the 1,740 earthquake reports in Areazine's archive by magnitude, stronger than 42% of them and weaker than 979 others.
Was Nikolski likely to feel this earthquake?
This event was centered 95 km SSW of Nikolski. 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.
