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 1 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 · AV, which has been reviewed by an analyst.

How big was it?
Usually not felt. Recorded by nearby seismometers; thousands occur worldwide every day.
It released roughly the energy of 8 g 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 0 km this was a shallow earthquake, which is felt more strongly at the surface than a deeper one of the same size.
M1.0 releases about 63× the energy of M-0.2, and its waves are about 16× taller on a seismogram. Energy: 477 g of TNT vs 8 g of TNT.
Each square is the energy of one M-0.2. Energy from log₁₀E = 1.5M + 4.8.
Aftershocks and nearby activity
37 later earthquakes within 30 km; the largest was M3.1 21 h ago. 11 in the 7 days before. Aftershock rates usually fall off roughly in proportion to 1/time.
Mainshock M-0.2
37 later earthquakes nearby. Aftershock rates typically fall off roughly as 1/time (Omori's law).
