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.
Estimated instrumental shaking IV (Light): Felt indoors by many; dishes and windows rattle and parked cars rock.
People who reported it described intensity III (Weak): Felt indoors; hanging objects swing, like a passing truck.
Felt it yourself? USGS collects first-hand reports through “Did You Feel It?”, and those reports are what produce the community intensity above.
