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 401 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?
Can cause damage over tens of kilometres, depending on depth, local ground and how buildings are built.
It released roughly the energy of 21 kt 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 116 km this was a intermediate-depth earthquake, which spreads shaking over a wider area but less intensely.
M6.1 releases about 32× the energy of M5.1, and its waves are about 10× taller on a seismogram. Energy: 21 kt of TNT vs 674 t of TNT.
Each square is the energy of one M5.1. Energy from log₁₀E = 1.5M + 4.8.
Aftershocks and nearby activity
No later earthquakes have been recorded within 142 km so far. 2 in the 7 days before. Aftershock rates usually fall off roughly in proportion to 1/time.
