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, 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 169 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 135 km this was a intermediate-depth earthquake, which spreads shaking over a wider area but less intensely.
M2.7 releases about 32× the energy of M1.7, and its waves are about 10× taller on a seismogram. Energy: 169 kg of TNT vs 5 kg of TNT.
Each square is the energy of one M1.7. Energy from log₁₀E = 1.5M + 4.8.
Aftershocks and nearby activity
18 later earthquakes within 30 km; the largest was M3.1 23 h ago. 1 in the 7 days before. Aftershock rates usually fall off roughly in proportion to 1/time.
Mainshock M2.7
18 later earthquakes nearby. Aftershock rates typically fall off roughly as 1/time (Omori's law).
