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 798 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 169 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 10 km this was a shallow earthquake, which is felt more strongly at the surface than a deeper one of the same size.

Compare M6.7 with M5.7

M6.7 releases about 32× the energy of M5.7, and its waves are about 10× taller on a seismogram. Energy: 169 kt of TNT vs 5.4 kt of TNT.

Each square is the energy of one M5.7. Energy from log₁₀E = 1.5M + 4.8.

Aftershocks and nearby activity

69 later earthquakes within 283 km; the largest was M5.5 21 days ago. 1 in the 7 days before. Aftershock rates usually fall off roughly in proportion to 1/time.
