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

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

People who reported it described intensity II (Weak): Felt by a few people at rest, mostly on upper floors.

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