Common Questions

What people usually ask about a notice like this one.

What magnitude was this earthquake? ▾

What does a magnitude 3.1 ("Minor") earthquake mean? ▾
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.
Is this earthquake stronger or weaker than others in the archive? ▾
This is the #1,569 strongest of the 1,834 earthquake reports in Areazine's archive by magnitude, stronger than 8% of them and weaker than 1,568 others.
Was Honaunau-Napoopoo likely to feel this earthquake? ▾
This event was centered 4 km SSW of Honaunau-Napoopoo. 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.
