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.

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 · CI, which has been reviewed by an analyst.

How big was it?

Usually not felt. Recorded by nearby seismometers; thousands occur worldwide every day.

It released roughly the energy of 256 g 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 19 km this was a shallow earthquake, which is felt more strongly at the surface than a deeper one of the same size.

M1.0 releases about 1.9× the energy of M0.8, and its waves are about 1.5× taller on a seismogram. Energy: 477 g of TNT vs 256 g of TNT.

Each square is the energy of one M0.8. Energy from log₁₀E = 1.5M + 4.8.

Aftershocks and nearby activity

112 later earthquakes within 30 km; the largest was M2.8 28 days ago. 29 in the 7 days before. Aftershock rates usually fall off roughly in proportion to 1/time.
