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 72 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 GFZ.

How big was it?
Widely felt near the epicentre: rattling windows and objects. Significant damage is unlikely.
It released roughly the energy of 274 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 79 km this was a intermediate-depth earthquake, which spreads shaking over a wider area but less intensely.
M4.8 releases about 36× the energy of M3.8, and its waves are about 11× taller on a seismogram. Energy: 274 t of TNT vs 7.6 t of TNT.
Each square is the energy of one M3.8. Energy from log₁₀E = 1.5M + 4.8.
Aftershocks and nearby activity
No later earthquakes have been recorded within 33 km so far. Aftershock rates usually fall off roughly in proportion to 1/time.
