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.
Estimated instrumental shaking III (Weak): Felt indoors; hanging objects swing, like a passing truck.
People who reported it described intensity III (Weak): Felt indoors; hanging objects swing, like a passing truck.
