Shaking is an estimate from the intensity prediction equation of Allen, Wald & Worden (2012), not an observation. Local ground and buildings can change it by a level or more. Likely felt out to about 16 km.
Every agency's solution
Agencies locate earthquakes with their own stations and methods, so their numbers differ. We match reports of the same event by time, distance and magnitude and show them side by side. The headline uses USGS · PR, which has been reviewed by an analyst.

How big was it?
Often felt by people at rest close to the epicentre, rarely causes damage.
It released roughly the energy of 747 kg of TNT. Magnitude is logarithmic: each whole step means about 32 times more energy and 10 times larger waves on a seismogram. Depth matters too: at 8 km this was a shallow earthquake, which is felt more strongly at the surface than a deeper one of the same size.
M3.1 releases about 35× the energy of M2.1, and its waves are about 11× taller on a seismogram. Energy: 747 kg of TNT vs 21 kg of TNT.
Each square is the energy of one M2.1. Energy from log₁₀E = 1.5M + 4.8.
Aftershocks and nearby activity
1 later earthquake within 30 km; the largest was M3.0 1 h 16 min ago. Aftershock rates usually fall off roughly in proportion to 1/time.
Mainshock M3.1
1 later earthquake nearby. Aftershock rates typically fall off roughly as 1/time (Omori's law).
