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 · AK.

How big was it?
Usually not felt. Recorded by nearby seismometers; thousands occur worldwide every day.
It released roughly the energy of 11 kg 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 90 km this was a intermediate-depth earthquake, which spreads shaking over a wider area but less intensely.
M1.9 releases about 22× the energy of M1.0, and its waves are about 7.9× taller on a seismogram. Energy: 11 kg of TNT vs 477 g of TNT.
Each square is the energy of one M1.0. Energy from log₁₀E = 1.5M + 4.8.
Aftershocks and nearby activity
2 later earthquakes within 30 km; the largest was M1.8 1 day ago. 5 in the 7 days before. Aftershock rates usually fall off roughly in proportion to 1/time.
Mainshock M1.9
2 later earthquakes nearby. Aftershock rates typically fall off roughly as 1/time (Omori's law).
| Time after mainshock (hours) | Magnitude | Depth (km) |
|---|---|---|
| 4.42 | 1.8 | 86 |
| 31.57 | 1.2 | 18 |
