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.
How does this compare with other earthquakes Areazine has reported? ▾

Was Cobb likely to feel this earthquake? ▾
This event was centered 10 km WNW of Cobb. 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.
