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 VI (Strong): Felt by all; furniture moves and some plaster and weak chimneys break.
People who reported it described intensity VI (Strong): Felt by all; furniture moves and some plaster and weak chimneys break.
