What the shaking was like

Shallow earthquakes release their energy close to the surface, so they are felt more strongly nearby than a deeper earthquake of the same magnitude.

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.
