No towns within 400 km. This is a remote area.

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, 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 15 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 473 km this was a deep earthquake, which spreads shaking over a wider area but less intensely.

M6.0 releases about 32× the energy of M5.0, and its waves are about 10× taller on a seismogram. Energy: 15 kt of TNT vs 477 t of TNT.

Each square is the energy of one M5.0. Energy from log₁₀E = 1.5M + 4.8.

Aftershocks and nearby activity

7 later earthquakes within 126 km; the largest was M7.0 19 days ago. 4 in the 7 days before. Aftershock rates usually fall off roughly in proportion to 1/time.
