Epicentre and nearby recent earthquakes

The highlighted circle is this earthquake. Smaller circles are other events recorded nearby in the last 30 days.

What the shaking was like

At this depth the energy spreads out before it reaches the surface, so shaking is usually weaker but felt over a wider area.

No intensity estimate was published for this event, which is usual for small earthquakes far from populated areas.

Felt it yourself? USGS collects first-hand reports through “Did You Feel It?”, and those reports are what produce the community intensity above.
