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 143 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?

Felt by most people over a wide area. Can damage poorly built structures close to the epicentre.

It released roughly the energy of 697 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 10 km this was a shallow earthquake, which is felt more strongly at the surface than a deeper one of the same size.

M5.1 releases about 33× the energy of M4.1, and its waves are about 10× taller on a seismogram. Energy: 697 t of TNT vs 21 t of TNT.

Each square is the energy of one M4.1. Energy from log₁₀E = 1.5M + 4.8.

Aftershocks and nearby activity

4 later earthquakes within 45 km; the largest was M5.3 17 h ago. 25 in the 7 days before. Aftershock rates usually fall off roughly in proportion to 1/time.

Aftershocks
