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.
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.
