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 129 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, which has been reviewed by an analyst.

How big was it?
Felt by most people over a wide area. Can damage poorly built structures close to the epicentre.
It released roughly the energy of 951 t 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 92 km this was a intermediate-depth earthquake, which spreads shaking over a wider area but less intensely.
M5.2 releases about 32× the energy of M4.2, and its waves are about 10× taller on a seismogram. Energy: 951 t of TNT vs 30 t of TNT.
Each square is the energy of one M4.2. Energy from log₁₀E = 1.5M + 4.8.
Aftershocks and nearby activity
No later earthquakes have been recorded within 50 km so far. Aftershock rates usually fall off roughly in proportion to 1/time.
