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 1103 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 serious damage over large areas. Roughly 15 such earthquakes occur worldwide each year.
It released roughly the energy of 477 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 18 km this was a shallow earthquake, which is felt more strongly at the surface than a deeper one of the same size.
M7.0 releases about 32× the energy of M6.0, and its waves are about 10× taller on a seismogram. Energy: 477 kt of TNT vs 15 kt of TNT.
Each square is the energy of one M6.0. Energy from log₁₀E = 1.5M + 4.8.
Aftershocks and nearby activity
3 later earthquakes within 300 km; the largest was M5.2 2 h ago. Aftershock rates usually fall off roughly in proportion to 1/time.
Mainshock M7.0
3 later earthquakes nearby. Aftershock rates typically fall off roughly as 1/time (Omori's law).
| Time after mainshock (hours) | Magnitude | Depth (km) |
|---|---|---|
| 0.64 | 5.2 | 10 |
| 1.80 | 4.6 | 10 |
| 2.19 | 4.7 | 10 |
